So, what is the consensus on this stuff? I have 114K on my SVT and have never run synthetic(When I bought it at 87K it was on dino and I didn't want to switch then). I have no leaks or any other problems, but would it be worth it use this stuff anyway given the mileage, or is it risky/pointless if there are no apparent problems? Also, no one has discussed the cost/benefits of using it on your tranny/diff...Any opinions? I am tempted to buy some, and I figure if I do I might as well give my tranny the treatment also. The website is pretty good, but of course they will not give any negative info, so what are everybody's honest KNOWLEDGABLE thoughts?
