Re: [FWDLK] Old cars and new gas?



In my 56 Plym with the stock 6cyl, I run whatever the high test is at the
station I pull into. Usually 92 or 93 octane and I don't use lead additive.
I always here it will damage the valves and then others say it's bullshit.
I figure with the little I drive if it's a problem down the road, I'll
rebuild.

But I've gone about 15,000 so far on high test unleaded.

Hello all,
I have a question about how you all handle new fuel in your older cars.  Of
course there is the problem of lead vs. unleaded, but I am also wondering
about
octane levels.  I know that for some of the hotter engines in the fin cars
the
engine compression ratio was very high.  (Like 11:1 and more)  In Colorado
premium pump fuel is 91 octane, hardly correct for 11:1 comp.  What do you
guys
do?  Is there lead/octane additives that you like?  Does anyone know if
altitude
has an effect on this as well?  Am I wrong, and 11:1 does fine on 91?   Just
curious,
Peter
