Does a Lexus Need Premium Gas?

Gas Pump Leaded vs unleaded

If you're the proud owner of a Lexus, congratulations are in order. You've made an excellent choice for a luxurious, high-performance vehicle. One of the first things you'll notice when you're behind the wheel is your Lexus's superior performance. From the IS to the LX, you have plenty of vigor at your fingertips when you drive a Lexus. Not only do you get outstanding performance, but you also enjoy impressive fuel efficiency on your drives all around El Monte, California. That's thanks to the advanced engineering and technology infused into every Lexus.

But before you hit the road, there is one crucial question that every Lexus driver should know the answer to: Does your Lexus need premium-grade gasoline? If you want to continue reaping the benefits of driving a Lexus, you should use the recommended fuel type for your vehicle. Some Lexus models require premium gasoline while others don't, so it's essential to know the kind of fuel your Lexus needs. Reference your owner's manual for precise fuel type requirements. Here at Longo Lexus, we've broken down the facts to help you better understand which fuel grade is best for your Lexus. 

Premium vs. Regular Gas Explained

So, you might be wondering about the differences between regular and premium gasoline. To help you understand the distinction, we figured we'd help to explain the two varieties. Your automobile requires small, carefully timed combustions to run optimally. Consequently, the octane rating of your fuel plays a significant role in the quality of these combustions.

Regular gasoline, also called "regular unleaded" or simply "unleaded," is the most common fuel for cars. This type of gasoline has an octane rating of 87 and is the cheapest option at the pump. Regular gasoline works just fine for most vehicles on the road; however, some vehicles require a higher-octane fuel.

Premium gasoline, also called "premium unleaded," has an octane rating of 91 or higher. When your car needs a higher-octane gasoline, it means that the fuel can better resist the unwanted combustions that happen when the air and fuel mix in your engine. If you have a higher-performance vehicle, like a Lexus NX, premium gasoline is typically recommended since the engine is specifically designed for it.

In short, premium gasoline is the way to go if your car requires higher-octane fuel. However, if your vehicle doesn't need it, you may not get any extra benefits from using it. So, when choosing which fuel to use for your vehicle, double-check the recommendations of your car's manufacturer. That way, you can ensure your Lexus gets the best performance possible.

Lexus Models That Require Premium Gas

Not all Lexus vehicles require premium gasoline, but a few do. If you drive any of the following 2023 Lexus models, you should fill up with premium fuel:

Lexus SUVs

Lexus Sedans

  • Lexus GS.
  • Lexus LS Hybrid.
  • Lexus IS.
  • Lexus LS.

Lexus Coupes

If you've misplaced the owners manual for your vehicle or just want to double-check with a professional, you can visit your local Longo Lexus dealership. Our knowledgeable and certified technicians will be able to answer any questions you may have about which type of gasoline is best for your Lexus. Also, don't forget to ask about any other essential services your vehicle may need, such as an oil change or tire rotation.

Advantages of Using Premium Gas

While premium gas may be slightly more expensive at the pump, there are many advantages to using this premium-grade fuel in your Lexus, especially if your car requires it. Here's a look at some of the main benefits you can enjoy when you use the correct type of fuel in your Lexus:

  • Better performance: Using premium gas in your engine can reduce knocking and pinging caused by the air-fuel mixture detonating prematurely in the engine. Premium gas also helps to keep your engine running smoother, improving overall performance.
  • Increased fuel economy: Premium gas has a higher octane rating, which means it burns cleaner and more efficiently. This leads to improved fuel economy as the engine won't have to work as hard and won't waste energy.
  • Improved engine life: Premium gasoline helps keep your engine clean, reducing the amount of dirt and grime buildup. This allows the engine to run better for longer and helps prevent major repairs due to engine wear and tear.
  • Cleaner emissions: As the name suggests, premium fuel has a cleaner burn compared to regular gasoline. As a result, it produces fewer emissions and reduces wear on vital motor components such as spark plugs and piston rings.

What Happens if I Don't Use Premium Gas in My Lexus?

Using premium gas as specified in your owners manual is essential if you own a Lexus model that requires it. While saving money by using regular gas at the pump may seem like a good idea, you may end up paying for it down the line. There are two big reasons why you shouldn't use regular gas when premium is recommended.

First, using too low of a grade of gas can lead to engine knocking, which can cause long-term damage to your engine. And second, using regular gas when you should use premium could void your warranty, meaning you would have to pay for any costly repairs out of your own pocket.

Although premium gas is more expensive per gallon than regular gasoline, the small savings you get from choosing regular gas isn't worth it in the long run. The cost of repairs and damage to your engine could end up being much more expensive than the extra cents per gallon you would save. Therefore, it's best to use premium gas when required to protect your vehicle.

Everything to Know About Lexus Warranty in 2026

Buying a luxury vehicle means investing in quality that lasts. When you purchase a new or Certified Pre-Owned Lexus from us at Longo Lexus, understanding exactly what your warranty covers protects that investment and gives you confidence behind the wheel. We're proud to offer Lexus warranty coverage that provides multiple layers of protection designed to keep your vehicle running at peak performance while minimizing unexpected repair costs. Explore our new Lexus inventory to find the perfect vehicle backed by comprehensive warranty protection. more Understanding Your Complete Lexus Warranty Coverage Every new Lexus comes with comprehensive factory protection that covers you from the moment you drive off our lot. The Lexus factory warranty includes several distinct coverage types that work together to protect different aspects of your vehicle. Your basic warranty shields you against manufacturing defects in materials and workmanship, while specialized coverage extends protection to critical systems like your powertrain and hybrid components. Here's how Lexus warranty coverage actually works in practice. Components that face the most stress receive extended protection periods. This layered approach means you're covered for what matters most, when it matters most. Understanding each coverage tier helps you make smart decisions about maintenance and future protection needs. New Vehicle Warranty Protection The Lexus new car warranty establishes the foundation of your vehicle's protection. Purchase a new Lexus from us and you'll receive bumper-to-bumper coverage for four years or 50,000 miles, whichever comes first. This comprehensive protection addresses virtually every component of your vehicle, from the advanced infotainment system to the climate control and beyond. Your powertrain gets separate, extended coverage lasting six years or 70,000 miles. This protects the engine, transmission, and drivetrain components that keep your Lexus moving smoothly. Hybrid owners benefit from even longer protection for their specialized systems. These overlapping coverage periods create a safety net that adapts to how different vehicle systems age and function. Bumper-to-Bumper Coverage The basic warranty covers repairs needed due to defects in materials or workmanship across nearly all vehicle systems. Your Lexus is protected against issues with the audio system, navigation, safety features, electrical components, and countless other parts. This coverage addresses the widest range of potential concerns during your first years of ownership. Some items fall outside this coverage. Regular maintenance items like oil changes, brake pads, and wiper blades that wear naturally through normal use aren't included. Damage from accidents, environmental factors, or improper maintenance also isn't covered. The warranty focuses specifically on manufacturing defects rather than wear items or external damage. Powertrain Warranty Protection Your powertrain warranty protects the heart of your vehicle. The engine block, cylinder heads, and internal parts receive coverage against defects. Your transmission, including the case, internal parts, and torque converter, falls under this protection. The drivetrain components that transfer power to your wheels are also covered, ensuring your Lexus delivers the performance you expect. This extended coverage period makes sense when you consider powertrain components represent the most significant potential repair costs. Having protection that extends beyond the basic warranty provides peace of mind during the critical years when your vehicle establishes its long-term reliability pattern. Hybrid System Warranty Benefits Lexus hybrid owners receive specialized protection for their advanced technology. The hybrid system warranty covers components unique to hybrid vehicles: the hybrid battery, battery control module, hybrid control module, and inverter with converter. For 2026 models and recent years, this coverage extends to eight years or 100,000 miles on the hybrid battery. Some newer Lexus hybrid models receive even more extensive protection, with battery coverage extending to 10 years or 150,000 miles. This demonstrates Lexus's confidence in hybrid technology and commitment to owners who choose environmentally conscious luxury. Additional Warranty Benefits Included with Every Lexus Beyond the core warranty protection, every new Lexus includes valuable additional benefits that enhance ownership. These supplementary coverages address specific concerns and provide services that keep your vehicle in optimal condition. Corrosion Perforation Protection Your Lexus includes protection against rust-through of body sheet metal for six years with unlimited mileage. This corrosion perforation warranty covers holes that develop from the inside out due to manufacturing defects in materials or workmanship. Surface rust or cosmetic corrosion isn't covered, but structural integrity is protected. This coverage proves particularly valuable in regions with harsh winters where road salt accelerates corrosion. The unlimited mileage aspect means high-mileage drivers receive the same protection as those who drive less frequently. LexusCare Complimentary Maintenance and 24/7 Roadside Assistance New Lexus vehicles include LexusCare complimentary maintenance covering your first two services. Your first service at six months or 5,000 miles and second service at 12 months or 10,000 miles include oil changes and multi-point inspections. Staying current with these services at our El Monte location helps maintain your warranty coverage and keeps your vehicle running optimally. Round-the-clock roadside assistance provides support for four years with unlimited mileage. Experience a flat tire, dead battery, lockout situation, or run out of fuel? Help is just a phone call away. Towing to the nearest Lexus dealership is included if your vehicle can't be driven. This service adds a layer of security that makes every drive more confident, whether you're commuting around Southern California or traveling cross-country. Lexus Certified Pre-Owned Warranty Benefits The Certified Pre-Owned Lexus warranty extends substantial protection to pre-owned vehicle buyers. Every Lexus Certified Pre-Owned vehicle undergoes a rigorous 161-point inspection performed by factory-trained technicians. Only vehicles under six model years old with fewer than 75,000 miles that meet strict condition standards qualify for the program. We provide bumper-to-bumper coverage for two years with unlimited mileage from the date of certified purchase. This coverage comes in addition to any remaining factory warranty on the vehicle. Your powertrain receives protection for six years or 70,000 miles from the original in-service date. Explore our Certified Pre-owned inventory to find quality vehicles backed by comprehensive warranty protection at exceptional value. CPO vehicles also include complimentary maintenance covering four factory-recommended services for two years or 20,000 miles, plus one year of roadside assistance. This comprehensive package makes Certified Pre-Owned Lexus vehicles an attractive option for buyers seeking luxury and reliability without the new car price tag. Extending Your Coverage with Lexus Vehicle Service Agreements When your factory warranty approaches expiration, Lexus Vehicle Service Agreements offer the opportunity to extend your protection. These plans allow you to maintain comprehensive coverage beyond the standard warranty period. Several plan levels are available, ranging from Powertrain Protection covering engine, transmission, and axle assemblies to Platinum Protection offering the most comprehensive coverage across multiple systems. Lexus Vehicle Service Agreements are designed specifically for Lexus vehicles and administered by the manufacturer. This means claims are handled through the same system as your original warranty, providing consistency and reliability. Coverage can extend up to 10 years or 125,000 miles from your vehicle's original in-service date. Purchasing a Vehicle Service Agreement before your factory warranty expires is typically more cost-effective than buying after coverage lapses. For owners planning to keep their Lexus long-term, these agreements provide budget protection against unexpected repair costs while maintaining the quality of authorized dealership service. Warranty Transferability Adds Long-Term Value The transferable nature of Lexus warranties significantly enhances your vehicle's resale value. Sell your Lexus before the warranty expires and the remaining coverage automatically transfers to the new owner at no charge. This benefit makes your vehicle more attractive to potential buyers compared to vehicles without transferable warranties or those from brands requiring transfer fees. Both the basic warranty and powertrain warranty transfer seamlessly. Even the hybrid system warranty transfers with the vehicle. This policy demonstrates Lexus's confidence in their vehicles' long-term reliability and commitment to all owners, not just the original purchaser. The transfer process is automatic and requires no special paperwork or fees. When ownership changes, the new owner simply needs to register with Lexus using the vehicle identification number to access warranty information and services. This simplicity, combined with the valuable coverage being transferred, often justifies a higher asking price when you're ready to sell or trade your vehicle. Experience Premium Warranty Service at Longo Lexus When you need warranty service, the expertise of your service provider matters as much as the coverage itself. We've maintained Elite of Lexus status since 1992, recognizing excellence in sales, service, and guest experience.

Lexus Battery

Which Battery is Right for My Lexus?

When it comes to keeping your Lexus running smoothly, understanding the type of battery your vehicle uses is crucial. Whether you drive a luxurious ES 350 or a versatile RX 350, the battery plays a vital role in performance and reliability. In this article, our team at Longo Lexus will explore the different batteries Lexus uses, outline how to identify when it's time for a replacement, and provide a handy guide for replacing your battery, ensuring your Lexus continues to perform at its best. more What Kind of Batteries Does Lexus Use? Lexus vehicles use various battery types, tailored to meet the specific needs of its diverse lineup. Learning about these batteries can help you make informed decisions regarding maintenance and replacement. Lead-Acid Batteries Lead-acid batteries have been the standard for conventional vehicles for decades. Lexus uses these batteries primarily in its gasoline-engine models. They provide reliable starting power and are relatively inexpensive compared to other battery types. Lead-acid batteries come in two main varieties: flooded and sealed. Flooded lead-acid batteries require regular maintenance, while sealed batteries offer more convenience with minimal upkeep. Both types effectively power your Lexus and keep it running smoothly. Nickel-Metal Hydride Batteries For hybrid models, such as the Lexus RX 450h, you'll find nickel-metal hydride (NiMH) batteries. These batteries store energy generated during braking and use it to assist the gasoline engine, improving fuel efficiency and reducing emissions. NiMH batteries have a longer life span compared to traditional lead-acid batteries, making them an excellent choice for hybrid vehicles. Their ability to handle deep discharges and recharge efficiently contributes to the overall performance of Lexus hybrids. Lithium-Ion Batteries Lexus has also started incorporating lithium-ion batteries in some of its newer hybrid models. These batteries offer greater energy density, meaning they can store more energy in a smaller and lighter package. This characteristic enhances performance and efficiency, making them ideal for today's advanced hybrid technologies. Additionally, lithium-ion batteries have a longer life span and require less maintenance, making them a popular choice among automakers looking to push the boundaries of electric and hybrid vehicle performance. How To Determine When It's Time for a New Lexus Battery Knowing when to replace your Lexus battery helps you avoid unexpected breakdowns. Below are seven signs that it's time for a new battery. Warning Lights If your dashboard's battery warning light turns on, it's time to investigate. Ignoring this warning can lead to more severe issues down the road, so we recommend visiting us to get a thorough diagnosis. Slow Engine Crank If the engine is slow to crank when you turn the key or push the start button, it could mean your battery is weak. You might notice this on cold mornings or after your car has been idle for a while. A sluggish start means your Lexus may need a new battery. Electrical Issues If you experience problems with your lights, power windows, or other electrical components, your battery might be failing. A weak battery can't supply enough power to run these systems effectively, leading to frustrating malfunctions. Age of the Battery Most batteries last between three and five years. If your Lexus battery is older, consider getting it tested. Even if it seems to work fine, age can affect performance, especially in extreme weather conditions. Corrosion Check the battery terminals for any signs of corrosion. If you see a white, chalky substance, it indicates a chemical reaction that can hinder performance. While cleaning the terminals can temporarily help, it might be a sign that you need a replacement. Unusual Smells If you notice a rotten egg smell coming from your battery, your battery could be leaking. This situation can be dangerous and requires immediate attention. Don't hesitate to bring your Lexus to us for a thorough inspection. Swelling or Bulging A swollen battery case often indicates internal damage or overheating. If you see any physical deformities, stop using the battery and reach out for assistance. Safety comes first. Step-By-Step Guide to Replacing a Lexus Battery If you need to replace your Lexus battery, here's a handy step-by-step guide to help you through the process. Remember, if you're unsure or uncomfortable, we're always here to assist. Gather the necessary tools: You'll need a wrench, gloves, safety goggles, and a replacement battery designed for your specific Lexus model. Turn off your vehicle: Turn your Lexus off completely and park it on a level surface. Engage the parking brake to keep the vehicle from moving during the replacement. Locate the battery: Open the hood and find the battery. It's usually situated near the front of the engine bay. Disconnect the negative terminal: Use your wrench to loosen the nut on the negative terminal (marked with a minus sign). Remove the cable and tuck it away from the battery. Disconnect the positive terminal: Repeat the process for the positive terminal (marked with a plus sign). Always disconnect the negative terminal first to avoid sparks. Remove the old battery: If your Lexus has a hold-down clamp, remove it to free the battery. Carefully lift the old battery out of the tray. Install the new battery: Place the new battery into the tray, ensuring it sits securely. Reattach the hold-down clamp if applicable. Reconnect the positive terminal: Attach the positive terminal first and tighten the nut securely. Reconnect the negative terminal: Finally, attach the negative terminal and ensure it's tight. Close the hood and test: Close the hood and start your vehicle. Check that all electronics function properly, indicating a successful installation.

Lexus Major Service

What Is Included in Lexus Major Service?

Owning a Lexus is synonymous with luxury, reliability, and top-tier performance. But like any vehicle, your Lexus requires routine maintenance to keep it running at its best. While minor services such as oil changes and tire rotations are crucial, more comprehensive care is sometimes necessary. That's where Lexus major service comes in. This essential service includes several detailed inspections, replacements, and adjustments to ensure your vehicle continues to deliver the performance you expect. Below, we'll explore what's included in a Lexus major service to help you understand its importance. more Understanding Lexus Major Service Lexus major service typically takes place every 15,000 miles, alternating with the regular 5,000-mile interval services.  It helps prolong the life of your Lexus, prevent breakdowns, and ensure optimal performance. Lexus also offers personalized maintenance schedules for your specific model. Oil and Filter Change Changing the engine oil and oil filter is critical to any service. In a major service, our Lexus technicians drain and replace the oil with high-quality synthetic or standard oil, depending on your vehicle's requirements. They also change the oil filter to ensure no dirt or debris affects the engine's performance. Oil lubricates moving parts in the engine, prolonging engine life and keeping your Lexus running smoothly. Neglecting regular oil changes can lead to costly engine damage down the road. Brake System Check and Brake Fluid Replacement Over time, brake components wear down, and brake fluid absorbs moisture, which can reduce braking performance. Our team thoroughly inspects the entire brake system during a Lexus major service. This includes checking the brake pads, rotors, and calipers for wear and tear, ensuring you can brake safely and reliably. Tire Rotation and Wheel Alignment An important part of a major service is rotating the tires, which helps maintain even tread wear, prolonging their life span. We also inspect the wheel alignment to ensure that your Lexus travels in a straight line, preventing uneven tire wear and enhancing overall handling. Air Conditioner Filter and Engine Air Filter Replacement We replace the engine and cabin air filters at every major service interval. The engine air filter ensures that clean air flows into the engine for combustion, while the air conditioner filter improves air quality, saves energy, and prevents your air conditioner from malfunctioning. Spark Plug Replacement Spark plugs play a crucial role in the combustion process, igniting the air-fuel mixture in the engine. Worn spark plugs can cause misfires, reduce fuel efficiency, and affect engine performance. Replacing them at the correct interval ensures peak performance. A spark plug change is usually recommended at the 100,000-mile mark, but a spark plug could be the issue if you're having trouble starting your car or hear an unusual sound. In that case, a thorough check and a possible replacement are recommended. Fluids Replacement and Top-Up Our major service includes inspecting and replacing several essential fluids to keep your vehicle running smoothly: Transmission fluid: It ensures the smooth operation of the transmission system, preventing wear on internal components. Coolant: It maintains optimal engine temperature and prevents overheating. Differential fluid: It lubricates the gears in the differential. If not changed on time, the differential becomes noisy and can eventually fail, seizing the gears. Windshield washer fluid: Ensures that you have clear visibility at all times. Our service technicians will inspect, top up, or replace these fluids as necessary. Comprehensive Vehicle Inspection A major service includes a detailed inspection of your vehicle's core systems. These include the following: Exhaust system: Checking for leaks or damage that could affect performance and fuel consumption. Suspension system: Inspecting components such as shocks, struts, and springs for wear or damage. Battery health: Ensuring the battery is fully functional and testing its charge to prevent starting issues. Lights: Making sure all headlights, taillights, and interior lights are working properly. This comprehensive inspection aims to identify potential problems before they become serious and keep your Lexus in top condition. Lexus Service Professionals Our Lexus-certified technicians are trained specifically to work on Lexus vehicles and use genuine Lexus parts so everything works perfectly. They also follow detailed service checklists, thoroughly inspecting and servicing every part of your car. This ensures that your vehicle will continue to perform optimally, reducing the risk of breakdowns and maintaining resale value.
