I quit using rotella in my duramax diesel, For various reasons that I will not go into detail. Oil analysis reports a lot and I'm tempted to do it with my yz. I would be interested to see how they hold up through various hour intervals and perform comparisons between different oils. We do soap samples on aircraft engines very very frequently, and the results are pretty wild and intriguing. A little overkill? Probably. But these are the technical details I like and enjoy.
This thread was not to be confused with a "what kind of oil should I use" topic. I was hoping someone had interpreted the label the same as I had, and throwing up a flag.
It's very simple, the Amsoil label is misleading, atleast for me it was. When someone recommends their product for certain applications... It makes one wonder why. However, After some clarification from Amsoil, it is basically mis-printed and is meant as a recommendation, in addition to.
Otherwise, one could very easily assume it's recommended for 2strokes and the transmission side of dual sump systems.
Anyways, moving on. Again, I value each persons response, on this useless thread.
