Premium Or Regular?


Recommended Posts

How many Lexus owners out there use regular?

I heard premium was a scam and regular wouldn't hurt your vehicle if you start off using regular from the beginning.

Is this true or is someone just feeding me BS!

I use premium as well. I will admit that I have used mid-grade in a pinch and suffered no problem. Our cars can adjust to lower grades, but I feel they are premium vehicles and they deserve premium fuel. Different grades of fuel ignite at different temperatures and compressions. By using the appropriate grade of fuel, the ECU can adjust properly for any engine load. By using the wrong grade, the window of adjustment becomes smaller and optimum fuel economy and power output can suffer.

Also IMHO, it makes no difference whatsoever what grade you start out with. I personally have never seen any data supporting that theory.

There is a large thread with every question asked already answered.

I know it is a long read but another thread is even longer to add to the list.

Please look in the general Maintenance section for it.

thanks
