Rick- Sorta took over this thread didn't we? RE: diesels vs gas wear on engines when all things are equal. Missed the boat on this one old freind. None of the stuff above (well maybe a little of some of them) has a major part of the wear formula. That is determined by the FUEL you use more than anything else. More specifically the by products you get from the combustion process. Those by products dictate wear more than anything else because they show up as contaminates in the
oil at both a micrscopic level and as corrosives in their chemistry. That's also why oils have additive packages, to counter the chemistry peice of this problem. Remember above I said "It's by far more important to change
oil every 3000K miles?" That's why I said it, the oils additive package breaks down. But of course the
oil itself remains stable. Scientific tests on this subject matter verify this wear relationship, and are out there on most of the internet oil companys web sites. In short, it's the fuel. Todays engines last in large part longer than than our 60's counterparts because the gas has less stuff in it to begin with. Together with better materials such as mollys, infused metal processing methods, etc. together with new techologys and today we have engines that last longer. In short, garbage in, garbage out.
