Since we're on the subject of gas.....
I've had to use 110 octane leaded CAM2 or Sunoco race gas in the twin cam
with its 13.5 :1 compression ratio. But it does get expensive!!
I was convinced to try Aviation Gas this summer up in Seattle, which seemed
to work fine...no detonation or performance issues. And it was 50% or less
of the cost of race gas.
Recently, I tried to buy more Av gas here in CA, but found a) that no one
would sell it to me in a jug...would only dispense it into a plane, and b) I
find that they now only sell "low lead" Av gas with an octane rating of 100.
I've heard that the "low lead" Av gas @ 100 octane is REALLY equivalent to a
higher octane automotive fuel, which I'd tend to believe since it worked so
well.
Does anyone out there have any definitive answers on using Av gas in race
engines? I hear stories pro and con about it. I would tend to agree that Av
gas comes under higher scrutiny and quality control than race gas..but is
there a downside?
Inquiring minds want to know???
