when I had my LT1 and continuing with my LS1 always 93 and always either Exxon/Mobil or Shell.. I dont ever go to Chevron or Texaco.. Just dont like them (and I have no reason for it.. just feeling i get when I see them..)

I also have almost every single gas reciept..
sad..
hehe
My psychotic display of my cars gas usage..

 

other!!! - 93

 

91 9 times out of 10. Ocasionally 93.

 

always premium which is 93-94 around here. Also an occasional shot of VP Red 116 for the track

 

93 here.
i seriously don't understand why people would put lower octane cuz of price. what do u save? .10 per gallon,,,so u save 1.50 $ for a FULL fill up ...i guess i don't understand cuz i don't watch pennies.
if you guys budget yourselves that closely,,u bought the wrong car !

 

another vote for the 93

 

i have only used 87 a few times, but i notice that when i use it i usually waste more gas with 87 than with 93. i travel about 200+miles a week and 93 just last a little longer, not to mention it has a more tolerant smell. i put 87 when i had LT's and a cutout and it smelled horible, but with 93 it was a little better.

 

94 is highest around here... and my baby likes it as much as i like rum and coke...

i never go lower than 93...

 

93 all the way for me.

 

91 and some STP octane booster 91 is all you can get out here in Southern CA and it is damn expensive.

 

I use 93 but voted for 94 cause you don't have it. My car is tuned to run 91 or higher, and if I go less, I will not take full advantage of the power tune

 

92 or 93, anything less and it runs a little crappy.

 

I voted other since I run 93...I have no choice...but even if I did I still only ran 93 before my tune

 

91 best they sell here...
