GMCers,
My dad has a 62' Chrysler Imperial that is experiencing vapor lock and other boiling/hot gas issues we sometimes do in our GMC's. A mechanic is his area of the East TX hill country (that works on antique Detroit iron) has recommended that he put about a quart of diesel fuel in a tank of gas to help alleviate/solve that issue (told to me second hand by my mom.) I think he needs to address other issues first, but I thought I'd ask this community if anyone has heard of this "solution" before and if it would work for our coaches. It sounds too simple to be effective; a bit like the "add a few ounces of acetone to your gas to increase your gas mileage." But then again who would think that allowing a duck or goose to stuff itself on corn or millet would ultimately give you something as yummy as foie gras?
Regards,
Rick

These things certainly do have a habit of recycling on the GMCnet.
About 2 years ago (July 2008) this subject came up.
I found my reply:

> They claim it does reduce the vapor pressure of the mixture and therefore helps prevent vapor lock.

> However, I have also read warnings that oil (Diesel fuel is oil) mixed into the gasoline can harm some of the gaskets and seals in the fuel system. That makes sense as oils will cause rubber swell in most elastomers (synthetic rubber compounds commonly found in fuel pumps and carbs, etc.
