If you don't ping with 87 octane, use it [burnout]

what does ping sound like?
 
Posted by st5150 (Member # 51) on :
 
Hard to describe. Sort of like crinkling up a plastic bag or sheet of aluminum foil. It usually happens around the RPM you make peak torque at.

best description that I have heard for the sound of pinging/detonation is marbles in a tin can.

as far as the question goes, I use premium because I'm just like that... plus I have my timing pretty advanced at the moment.

91 octane with a little toluene to bump up the octane a little.

Im testing out the different gasolines. I went from arco 87 to 76's 91 and noticed a big difference, currently im testing out 76's 89 octane.

i heard arco has very watery gas [Confused] probably not enough to notice im guessing

I use nothing but 76 in both of my cars. The mustang 91, the Tahoe 89. It's the cleanest...........plus NASCAR usues it so it has to be good [Big Grin]
