Let me start by saying, yes, we *DO* own a Lexus in our family. And yes, the average joe car owner is NOT a tuner so he doesn't know much about cars.

But I've been reading a Lexus forum and it makes me ashamed to own one. Keep in mind this is a thead in the General Maintenance forum and some Lexus's require 91 and some (like mine) just 87.

Check this out, especially starting on page 5, a thread about which octane to use:

Some choice quotes:


-any one that tells you that it does not matter what fuel of octaine is a complete jerk off, its plain and simple the better octaine the better proformance, dont every go lower, your car will feel sluggish,

- PINGING MEANS IT IS TIME TO DOWNSHIFT.

- remember that we have LUXURY cars meaning that we shoud spend a little extra money on things that we normaly wouldnt need to on a economy car like gas. so just put in the 91

- Hey, do you know what that pinging is?
It's the sound of the cylinder walls vibrating like a bell! ....Ouch.
Real detonation is not the same as pinging, and can destroy an engine. Modern knock sensors keep that from happening.

- Use premo ONLY in your car. Regular gas creates a lot of carbon buildup as well. Regular gas gives you less gas mileage than premo and I have a noticable less amount of power. I step on it a lot and I do notice the difference in gas. The increased gas mileage with premo just about washes out the extra money spent. Plus your engine runs better and cleaner.

- Well actually, if the ECU is designed to run on regular, and you run premium you're causing as many problems as if its designed to run premium and you run regular. The timing and combustion is set for one grade of gasoline, use what it says to use, no more, no less. High test in a regular motor causes pinging, carbon deposits, and robbed fuel mileage too.

- if you use higher ocane then recommended your seals will get burned as well due to higher combustion temepratures. it means blue smoke and $$ to waste
