Lmfao ! No tricks ...fair ?s but I run the apu as much as I ever have and at 21000 hours now it has been on allied 15w40 oil since new .
Nothing has changed including my very conservative drain intervals always before 800 hours .
I'am not real familiar with those small kubota motors .. I know their real good motors .. I've work on the bigger motors the 50 & 100 hp ones just rebilt 1 a couple mths ago in a Bobcat skidloader ..
To be honest I'am not familiar with APU in general.. I just idle my old truck when is cold and get me a large size lot lizzard to keep warm
I can't afford a APU.. cause I spend alot of my money on hookers & blow
I just ordered my buddy a 12v electric blanket cause he was telling how his co-driver didn't wanta get out of the bunk the other morning cause it was cold
I got him a red & black checked patterned 1 so they could play a game of checkers before they get horizontal
