I recently gota 96 Z28 camaro if u saw my last thread, but i was wondering what gas i should be running in it.. the guy i bought it from said lately because of prices hes been running 87 octane in it.. ive heard before that you should be running 89 or 91 ... what are the opinions on this and what are the facts i guess im asking =).. idont want to screw it up, so i need to know what gas is best to run in it, and if i can get off by just getting 87

run 91 or higher due to your compression ratio.

you can run 87 octane as others have done it. although you will experience knock retard due to the lower octane levels.

I ran 87 for about a month, then switched to 93 and experienced a huge change it power, response and just overall. Running regular won't do anything to your car, just isn't recommended. Also, try and search next time, i think they're a thread on this with like over a hundred replies or something.

I'm not sure what the last owner was putting in it, but I put in 87 for the first few times I filled it up.......just switched over to 93 (right in line with the increase in prices, lucky me) and I'm happy with the results. It'll be 93 from here on out.

Read your owners manual, it says to use 91 octane or greater "for best performance."

Hit up the local mnop and buy some 100 no lead and mix it with 92 octane the cars run awsome with it

the lower the octane you run, the easier you probably need to drive it. some bad low octane gases can cause so much knock that you'll get ping regardless of the retard under high load/low rpm's especially. but, you should be able to run 87 with no problems with an easy foot, which will also force you to get better mileage.
