I used this in my kubota m7040 tractor and I'm very pleased with the product. Usually after runnning regular oil in it, after just a couple of hours it will already turn black, but after running 40 hours on the AMSOIL, it is still very clean.

I am a long time user of many Amsoil products and am very happy with all of them. I never worry about wear in my Duramax with Amsoil Max-Duty Synthetic. I was convinced that Amsoil was a far superior lubricant after reading about Amsoil's initial development. This was high-tech before high-tech was common outside of military applications. It took real vision and perseverance to develop synthetic lubricants that are truly affordable.
