What happens if I don’t fill up my Lexus with premium fuel?
Your Lexus’s performance and power may suffer if you don’t fill it up with premium gas. This can eventually result in engine damage. Lower-octane fuel won’t directly harm the engine, but it can make the engine make knocking and pinging noises as the air/fuel mixture ignites too quickly in the cylinders.
Fortunately, not every Lexus car needs premium fuel. The more entry-level Lexus cars typically don’t need premium fuel.
To be absolutely certain, you can always examine the owner’s manual or your nearby Lexus dealer.
What happens if 87 gasoline is placed in a 91 vehicle?
When a vehicle manufacturer specifies premium fuel, it’s because the fuel system of that specific vehicle is built to function best with higher octane fuel. In an engine that needs premium fuel, using normal petrol could violate your warranty. That is most likely to occur if repeated use results in severe engine knocking or pinging (premature fuel ignition, also known as detonation), which harms the pistons or other engine components. Other issues, such as worsened engine performance and poorer fuel economy, may result from using the incorrect gasoline.
As an illustration, the following is what GM states about the matter in the owner’s guide for a car that needs premium:
91 or higher posted octane premium unleaded gasoline should be used. If the octane level is below 91, you risk damaging the engine and voiding the warranty on your car. When using gasoline with an octane rating of 91 or above, the engine requires maintenance if loud banging is observed.
Keep in mind that this only applies to engines that demand premium gas. Although some manufacturers advise using premium gas, you can also use standard or mid-grade gas. Usually, they mention that using gas with a lower octane rating could affect performance and fuel efficiency. They advise using premium when that starts to become noticeable, or if engine knock starts to happen.
Does my Lexus RX 350 suffer from ordinary gas?
Only unleaded fuel with an octane level of 87 or higher is permitted in the RX. As the premium octane rating is 91 or higher, the Lexus RX does not require premium fuel. Of course, you are welcome to fill up your Lexus RX with premium fuel if you want better performance, but it is not necessary.
What occurs if I put unleaded in a high-end vehicle?
According to 11Alive, drivers should avoid using regular gas in a vehicle that only accepts premium since the lower octane levels in unleaded gas could result in “knocking that destroys the car’s motor.” Your warranty could also be voided.

87 normal gas is it?
Any type of gasoline with an octane level of 91 or higher is commonly referred to as premium gasoline, with 91 octane and 93 octane being the most popular brands sold at gas stations in the United States (93 octane gasoline may be called “ultra or “super-premium in some cases). Most gas stations designate gasoline with an octane level of 89 as “midgrade,” whereas gasoline with an octane level of 87 is known as “regular.”
Does 93 octane make a difference?
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 cases, using gasoline with a higher octane rating than your owner’s manual suggests offers 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 regular 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
