<< An interesting byproduct of lead is the buildup of a cushioning effect on the seats that helps prevent seat brcoming recessed... >> That's what I always thought myself- thing is, the information available on TEL does not bear this out. Matter of fact, it directly contradicts the idea that TEL builds up. The scavengers that are/were designed into the additives are there to remove the lead. To quote the previous post "They then had to remove the lead, which would otherwise accumulate and coat the engine and exhaust system with lead. They discovered and developed the halogenated lead scavengers that are still used in leaded fuels. The scavengers, (ethylene dibromide and ethylene dichloride), function by providing halogen atoms that react with the lead to form volatile lead halide salts that can escape out the exhaust." So who do I believe? The engineers or the good ole boys? So far the engineers have a pretty strong case, but I have an open mind- Where is a chemical engineer when you need one? Dan NAA60512
