What grade do you use for your 1998 - 2005 GS4?
The owner's manual recommends "Premium", but what is considered "premium"? I personally always put in 93. Is 89 considered premium? If so, I think I will save a few pennies and switch to 89.

Sometimes price difference of $.10 is not a big deal between 89 and 93. I fill it up every 2 weeks so it doesn't make too much of a difference for me.
I usually put the highest they have.

Wait, so they have 92? I've never seen 92 before.
I am currently using 93 and will continue to use 93. I do not plan to use 89. I didn't know what "premium" was. So, I played it safe by using 93.
I know here in NYC we have 87, 89, 93 & 94.
I know in some states, you guys have 86.
How about 91 & 92? Are those available to some of you? I'm just curious.

So basically if you live in SoCal & Vegas, you can't get "premium" fuel (which is recommended)?

91 is Premium for us. It use to be 92 but for some reason they brought it down to 91 about 4-5 Years ago.
This is how it goes.
87 - Regular
89 - Plus
91 - Premium
I guess it's because of the Strict Emissions we have here in California

But, when Lexus says "Premium" what do they mean? I think it would be more specific if they gave it an Octane number instead of vaguely stating "Premium".
