I responded to your last post about this. What makes you think the lube was the culprit? You always hear about failures from bad lubes and every time it ends up being metal fatigue in a part or parts, improper assembly, or something else. Lube-related failures seem to be an urban legend other than the seemingly increasing cam failures do to low-zinc oils. If there was an actual problem with a batch of lube it would not be just one person who had problems, it would be hundreds, if not thousands of customers. Before I switched to Amsoil I spent tons of time checking them out and I found tons of positive reviews of their stuff and not one complaint. That is why I switched, not because of anything Amsoil had to say. Obviously, I do not know your situation but it seems to me that if they put out a bad batch of product, contaminated or whatever, you would see complaints all over the place. Yours is the only one I have ever seen. I don't mean to challenge you, it just doesn't make sense. If any company did put out lubes that trashed engines or trannys they would be put out of business because the word would get out and no one would buy their stuff. It just seems that when you have thousands of people buying and using the same product and only one of them has a problem the probability that their problem was caused by the product is just about zero.
