I have good results running a high percentage of wmo. Running it through simple filters and into the truck. I try to keep one tank with mostly diesel and the other is mostly oil. Too strong on the oil and it bogs down (starves for fuel) and will stall, but switching teams several times mixes the fuel between tanks enough to run well on it.
