What type of fuel?

[mtcs]

What kind of fuel..(ie: 87,89) should I use on my 1988 camaro? It is a 2.8 V6.

Ive been using 89...but can I use 87 without losing any power..or any drawbacks.

Thanks

your owners manual tells you what the minimum grade you can run is.

I do not have the owners manual for the camaro. I just bought the car.

i'm pretty sure it's 87 then, my 91's manual says 87.

i'm pretty sure its 87, almost all cars are recomended to run 87, the only ones that i know arent are cadilacs, they run 90+
