94. . . why ??

TravWS6

i'v ran everything and anything.. i stick wit chevron.. sometimes she runs like sh*t with low octane.. but i also got a HPP3.. that requires 92 i think. o well

hi

Chevron 94 octane since day one.

depends on what gas is at. if its reeally high i run 92 otherwise i usually run 94 both from chevron "you're town pump"

mr_muff

chevron premium 94 only

but you can run them on 92

NiteRider

Interesting feedback, I figure only the two Mikes should be runniing 94, mike p and mike s, I thought you guys would be running 89 when the prices are really high and 92 when there not so high.

Damn, you guys pamper those engines to much.

Good god... 89??? Never. Chevron 94 always. The car is not recomended for less than 91 (not that the manufacturer's recommendations are a big deal), and with a ported MAF, like i have, it is very common to get detonation with 91. Hence, 94. 92 is likely to have no noticeable negative effect, but I like the good stuff.

If you drive like a granny, then you might use cheaper gas and never know the difference - but who drives like that? In the whole scheme of things, the cost savings is COMLETELY insignificant in my opinion.

Some LS1 years are better too than other years for handling different octanes (at least it SEEMS to be that way), depending on the programming from the factory. Later years are supposedly not as good with lower octane. But, I've never seen this firsthand.

Honestly, I don't know how much of a diff it would make on the dyno or mileage - but if you have any form of a ported intake, or anything else that advances the timing, then 94 is a safe choice.

haha i argee wit u niterider!! i only run 89.. 94 when the big checks come in... y do it if ya don't have to right?

TravWS6

u got a good point there Chris.. personaly i listen to the motor.. put the gas in.. if it makes noises and doesn't run well i steep up the octane.. but ya for sure if im out to have some fun i put good stuff in!
