Does Lexus Require Premium Gas|Lexus rx 350 Regular or Premium Gas
A premium fuel is usually any fuel that has a high octane rating like 91 or higher than that. Any Lexus with this kind of requirement is said to be using the premium gasoline.
Regular fuel on the other hand, is the one that has an octane rating of 87 or lower. If this is the requirement of your vehicle, then it does not need the premium gas.

What kind of gas does a Lexus ES 350 take?
If you are asking yourself the type of gasoline the Lexus ES 350 takes, then there is no need to keep asking that question.
The vehicle uses a regular gasoline which means that it requires fuel of about 87octane rating and not higher than this.
You need to be aware of the kind of fuel your vehicle needs. Putting a premium fuel in the ES 350 may greatly affect the engine.
It can cause a metallic-knocking noise in the engine which could in turn, affect the optimum performance of the engine.
The worst thing that may also happen is that it can damage the engine, and this could require a lot of cost for repair.
So, it is advisable you use the correct type of fuel for your Lexus ES 350.
Does the 2015 Lexus RX 350 require premium gas?
My response to this is No. The 2015 Lexus RX 350 vehicle, does not require a premium gas and that is because, every model of the Lexus RX 350 from 2012 to the newer ones require a regular gasoline of around 87octane rating and not 91.
What this means is that the gas you need to fuel the vehicle should have at most 87octane rating for a regular gas and a 91 octane rating for premium gas.
Pouring a premium gas or any other gas in your Lexus RX 350 can ruin the car’s engine. This is something you want to avoid, as a car owner.
What happens if you don’t put premium gas in a Lexus?
This question is common among Lexus car owners because their vehicles are known for being luxurious.
So, it is expected that they use premium fuel. However, what you should know is that every model of Lexus requires unleaded fuel.
Note that the octane rating of every model varies mostly by year. This is the one reason why some models of Lexus require the use of premium gasoline, while others require the regular gasoline.
The vehicles that use the premium fuel have the fuel requirement of 91octane rating, while the ones that use regular gasoline have a fuel requirement of 87octane rating.
You should ensure you fuel your Lexus with the required fuel so that you do not knock your engine. When you do not adhere to the requirements, you risk damaging the engine.
What happens if you mix premium and regular gas?
Mixing a regular gas and premium gas is disastrous and not advisable. You should know the required fuel for your vehicle and ensure you stick to it.
A mixture of regular and premium gas can cause a loud metallic noise in your engine. You may also hear a severe and constant pinging noise from the engine.
Engine detonation may also occur if you mix regular gas and premium gas. The worst thing that may happen is that the probability of your engine getting damaged is high.
You may end up damaging the engine which could cause you to spend a lot of money to repair it. Mixing a regular and premium gasoline will void your warranty even if your Lexus is new.
Vehicles that use premium gasoline are usually of high performance, while the ones that use low premium engine are of low performance ones.
High performance engines usually have higher compression ratios than the other cars that can work fine on lower octane gas.
Always ensure to use the required octane ratio of your vehicle. Doing the opposite will not benefit you but may only cause you more damages.
Can I switch from premium to regular gas?
Every vehicle has the required type of fuel it needs. The type of fuel every vehicle needs is usually written in the manual of a car.
Most vehicles that use premium gas can also use lower grade gasoline. This is due to the fact the premium gas might sometimes be scarce to get in some areas, so lower gasoline can be managed.
However, you will have to switch back to premium gas once you start hearing some knocking or pinging symptoms.
So, it is important to use the right type of fuel or gas in order to prevent damage of your vehicle. Premium gasoline is usually used by cars with high performance, while regular gas is used by vehicles with low performance.
The octane rating of vehicles can be different. This means that they use different type of vehicle. Premium gas has a higher rate than regular gas, and this makes it produce more power. It is usually useful to vehicles that have a powerful and large engine.
