Questions about fuel grades.
I've been running 87 octane in my 98 Z28 with no problems. Now, I have a 2000 SS, and inside the fuel door is a sticker that says "PREMIUM Unleaded recommended". my questions are:
Was the same sticker on my 98, and it's missing now?
Is the sticker on the fuel door of my SS only on the SS's?
Or, is the sticker on certain years?
Premium unleaded around here is 89 octane. Is that good enough? Or is the Super unleaded 93 octane what they mean by Premium?JIGGER RACIN'

You should be running only Premium in your car. At least 91

It's always been recommended to run at least 91 in the LS1-even the 1998's. I have a sticker on my Z28, but it was in the owner's manual for all LS1's. The knock sensor will allow lower octane-but you will lose performance. I have found a station that sells the 93 octane for $.10 over the lowest stuff. But even if you pay $.20 more a gallon that is less than $3.00 a tank for better performance. I will pay the $1.50 extra myself to take better care of the motor. If you think about how much some people will shell out for performance parts compared to the extra cost of premium gas-it's cheap.

if anything the 98 would need the premium the most due to more aggressive timing tables than the 99+ but either way you should run it on all LS1's
