Well almost B100, I did put a few gallons of petrodiesel in this winter. The distributor who took the sample and sent me the report said he would come down next week and go over it with me. Whoever did the report at AMSOIL told him that we make some good fuel, that made me feel good.

He suspects there may have been some leftover residue from the previous oil, not sure what that was but it was a diesel oil. He said to change the filter and go another 5K or so and he will pull another sample

Using AMSOIL Synthetic Blend 15W-40 Heavy Duty Motor Oil (PCO)

Any comments on these results? I use Mann filters
