I recently became a dealer and changed all my truck fluids over to AMSoil. Differentials, transmission, engine oil and coolant. Brake fluid is next.

My Kawasaki Ninja 650r has had the oil changed to AMSoil for some time now.

Then it's off to my wifes car and the lawn care equipment. I'll see if I can remember to post any findings I have, here in my Blog.
