That's the same TEL used in all leaded gas, although aviation fuel does have more. Even the low lead aviation fuel has significanly more lead than was typically used even in high octane car fuel. Even so, I'm skeptical that this would bea significant factor considering the mileage and indoor storage many of these trucks get.
I have also heard that the formulation of aviation fuel is such that it burns significantly slower than car gas, thus exhaust valves tend to run hotter. This was told to me by an old hot rodder, so it may be a wives tale. Anyone have any data to back this up?
