[FWDLK] Correct Octane Gas for Our Cars

[Ron Waters <ronbo97@xxxxxxxxxxx>]

Hi Gang -

I've always used mid-grade octane gasoline for my 58 Plymouth with a 318. 
Here on the east coast, mid-grade is 89 octane. I was told recently that 87 
octane would be fine for this engine. When I questioned this in comparison 
to the old 89 octane leaded gas that we used to put in our cars, I was told 
that octane is now calculated differently and, again, the 87 octane would be 
fine.

What do most folks use for small blocks engines like the 318 ?

Thanks,

Ron
