To be absolutely certain, you can always examine the owner’s manual or your nearby Lexus dealer.

Premium Gas Offers Better Performance
This myth is partially true and partially false. The majority of automobiles operate at the same level of performance whether you use standard or premium petrol. You’ll only notice a noticeable difference between the two with particular car models and engine types.
You Need to Use Premium Gas if It’s in Your Car Manual
This myth also rests on circumstantial evidence. Many automakers, like GMC, Ram trucks, and the works, will indicate in the owner’s manual for some of their cars whether they advise or demand the use of premium gasoline. What counts is how these two terms differ from one another.
There are certain advantages to using premium gas when the manual advises against it, but using regular gas won’t hurt your car. It won’t void your warranty in this situation either. Premium gas could potentially improve the performance of these vehicles.
But if the owner’s handbook specifies premium fuel, it signifies the engine does really require higher octane levels to operate properly. Using conventional fuel in these vehicles could potentially harm the engine, and your warranty won’t cover these damages.
Make sure you carefully study your owner’s manual before buying a new or used automobile to make the best decision. Save yourself the money if it’s not necessary.

Since the higher octane levels are what set them apart, the only true advantage is a decreased risk of engine knocking, which poses no danger with most contemporary fuel systems.
Premium Gas Cleans Your Engine

Is premium fuel actually worthwhile?
Why spend a lot of money on something you don’t require? Premium petrol costs around 50 cents more per gallon than regular gas and doesn’t affect vehicles that can’t use it in any way. The Federal Trade Commission warns consumers that, “In most circumstances, using gasoline with a higher octane rating than your owner’s manual suggests delivers absolutely no benefit. It won’t improve the efficiency, performance, speed, or mileage of your vehicle.
In order to clean your engine and improve performance, the detergent additives in your gasoline are significantly more significant than the octane rating. Every shop offers a unique mixture of additives that are applied to all grades. For instance, Chevron’s Techron is available in both their normal and premium gas.
Some people hold themselves to a higher standard when it comes to additives. The Top Tier Gasoline standard, which requires a higher-percentage of detergent additive than the EPA minimum criteria, was developed with the assistance of BMW, General Motors, Honda, Toyota, Volkswagen, and Audi. They contend that lesser detergent additive concentrations may cause greater deposits to form on engine parts like the intake valves and fuel injectors. As a result, emissions may rise and engine performance may be affected. j
