>Lead in fuel has no appreciable effect on normally operated engines other than to slowly poison us and our neighbors. I beg to differ on that point, as it has been shown many times that older iron block and head engines DO need the lead (or a suitable substitute) to prevent valve seat wear. This may not apply to vehicles in the US where you have had UL fuel for many years and motors will have had hardened seats fitted, but try running an old British car such as an MG on UL and watch those valves close up before your very eyes. And I'm not just talking about cars which get thrashed flat-out all day, just ones that get used normally. What is true, though, is that assuming the octane is high enough to stop pinking (pinging) then the car will run fine without the lead. Until the valves burn out. I suppose we had it easy over in Europe in the sixties. A Jag E-type is meant to use what used to be called 5-star fuel which was 100 octane. Just try running that on your Wyoming 87 octane with ethanol! Sorry that wasn't strictly T3 related, but it has to be said. ------------------------------------------------------------------- Pitch in! Send your pledge of support! mailto:support@vwtype3.org
