LT1's happy with 89 octane gas?
 

When I first purchased my car I ran 87 which basically made it run like crap. I then switched to 93 and now with the HPP+ program installed running 93 is a must (do not turn this into a HPP+ bashing thread). Due to continue rape of gas prices I'm considering removing the program and switching to 89 octane fuel, will their be a problem with running this level of fuel? I know most people (including me) like treating their F-Bodys to the best of everything but my wallet is getting kind of thin here. If worst comes to worst I could always run a little octane booster and pick up like half a point lol.

Right before I started having my tranny problems, I ran a tank of 89 through it. It is much better than the 87, but it still pinged and ran like ****. I also just recently installed my new PCMforless PCM, so that might have had something to do with it too. Brian told me that it wouldn't like anything but 93.

I would never run anything but 93 in mine.

LT1 kinda need premium(93). it even says it in the owners manual i think. could u drive it easy with 87/89, yes, but even under slight acceleration it will prolly ping. fork over the dollars or dont play. thats all there is to it. i guess the best answer is have a fuel efficient car for a DD and camaro for cruising and weekend things.

93 octane for me two its programed for it now so i wont chance it

93+ is all i run in my car.. its a ls1 but still... its sittin with a full tank in my garage with the tranny cooked i might stick a hose in her tomarrow...

Thanks for the feed back guys, I'm just going to bite the bullet and run 93+. I figure if I can afford to run Royal Purple I can afford the good gas.:) And BTW if anyone wants cheap octane booster I found some O'Reillys, if you buy over 3 bottles you only pay a dollar bottle but I doubt this stuff has any real strength. On a different note I find it funny when I was young and stupid (senior in HS) all I did was run 87 in my car. I remember when I ran my tank down real low and filled it up with 93, even the tone in exhaust changed. :eek:
