Joe,
Thanks for the link. That was very interesting about the teflon, I was one of the people who bought slick 50 years ago to put in a gas engine. I never had any problems with it, but more experience with fleet trucks has shown me that it is totally unnescessary. The last company where I worked ran hundreds of s-10 pickups, mostly with the v-6s, and mostly stop and go city driving. We changed the oil every 3000-5000 miles with the regular jiffy lube kind of stuff. We never had any problems that were wear related in the engine before at least 150,000 miles were on the trucks. When I left, I had a truck with 130,000 miles that ran like new because I kept the oil changed.
Last week at the VA state Samboree, I met a guy who has been working and rebuilding diesels for 30 years, mostly tractor trailers. He has never used additives, and says they are totally unnecessary if you just keep the oil changed. He said that your main problem is with the fuel. He has used many different fuel additives and recommends FPPF as the best when it comes to pump lubrication and water dispersion. He also talked about fuel bottoms that are sold from the bottom of large fuel storage tanks that sell really cheap to the lesser known dealers. He said also to watch for the big filter on the side of pumps, that is a good sign that you are getting good fuel, some places don't even filter the fuel. He has a shop in PA, if I can find his card (I think it's out in the trailer) I will post it.
