Re: Vapor lock poll

Brian, I'm sure you know you need quite higher compression ratios, 16 to 1 and generally much higher, to efficiently extract the power from diesel or kero. So if you add enough diesel to your gasoline to notice the effects, you'll have less power, more visible (black) smoke, a tendency to foul plugs and valve stems, perhaps carbon-up piston tops and rings, etc.

But a fair # of old car owners have reported using it in amounts of about 1 gallon or so per 20 gallons of gasoline without difficulties. Whether they used it long enough for such problems to manifest themselves, or even if they would, is not known to me. Still, my suggestion was just to use it confirm that you have a vapor lock situation, and not as a cure. Having never had a vapor lock problem, I have no first-hand experience with it - just what I've heard and read.
