Many car owners are oblivious to the fact that their cars require a specific grade of gasoline for them to, not just get the best performance out of the car, but also prevent their car’s engine from getting damaged.

Unfortunately, whether you know it or not, it doesn’t matter. Filling your car up regularly with the wrong type of gas will eventually damage the engine of your car.

What’s Type Of Gas Does The Lexus IS 250 Require?

The Lexus IS 250 requires premium gas. This is the recommended type of fuel by the manufacturer.

What Are The Different Types Of Gas Used By Cars?

We have different types of engines in cars: standard and high-performance engines; that require different grades of fuel to achieve optimal performance.

There are three different types of gases: Regular, Mid-Grade, and Premium Gas.

The difference between these three types of fuel is their level of octane.

The level of octane in the gas will determine how the gas is burnt by the engine, and the lower the octane level, the faster it ignites and burns.

Regular gas has an octane level of 87, mid-grade has an octane level of 89, and premium gas has an octane level of 91.

The way cars work, once you turn your ignition switch, a spark is sent into the engine’s cylinder, which then comes in contact with the fuel and air in the cylinder, and ignites a kind of small explosion, which starts the car.

Unlike regular and mid-range gas, premium gas will not ignite and combust as fast, which allows fuel economy and is used mostly in luxury cars with high-performance engines.

Cars with standard engines mostly make use of regular or mid-range gas because their engines do not require gas with high octane value or premium gas.

However, most luxury cars require premium gas because of their high-performance engine requirement. Luxury car manufacturers would usually recommend premium gas.

You don’t want to fill a car with a high-performance engine with regular gas because regular gas burns quickly and won’t maximize your car’s speed and performance.

Using the type of gas your car’s manufacturer recommends will help you get the best out of your car.

These fuels combust at different rates so, they affect the performance of your car.

Why Does The Lexus IS 250 Require Premium Gas?

The Lexus IS 250 uses a high-performance engine, therefore, it requires premium gas with high octane levels so that it can function efficiently.

Using fuel with a lower octane level in this car will lead to pre-ignition and cause the fuel to combust too fast for the engine which will reduce the car’s efficiency, and fuel economy, and create knocking which will damage the car’s engine.
