I was wondering if i should put 93 in it or if 87 is good? Anyone know which is better?

87, no need for anything higher in an N/A. They run better on lower octane gas.

87 octane is what I run. I ran 93 octane once and it didn't really do anything other than put a dent in my wallet

87 lower ocatane performs better in NA's

I was told that lower octane is more volatile, is that true? Also, that higher compression engines use higher octane, because they ignite at a higher temperature. So, that would mean that, unless you have a high-performance, high-compression machine, lower octane is actually better, right? Am I close?

I put 87 in mine.. only put premium in it once, to pass smog..

I guess the question is how low can you go? Someone told me that they once put 80 in theirs, but they were probably bullshitting me. Nothin but 87 for me.

always 87



sometimes higher when its the only pump avail. or when i make a mistake

What about premix? We decided that premixing lowers the octane about 1 point, was it ever decide that 86 was good enough, or should you switch to 89 if you premix (giving a working octane of 88)?

where did he find 80?
