I run a
Pure Power one pass
oil filter. which means that the
oil is filter in one pass through the filter media instead of flowing along the side of a paper filter into the plastic by pass. Anyone that is running the cheap five dollar
oil filter on their $20,000 or more FE is crazy in my opinion. Its amazing the stuff the filter trapped, and I was extremely careful during the engine assembly process.
I also run Rotella T in the Cobra and the Yamaha FJR1300
