So, silicon appears to have increased and the trending is going up for this 2nd UOA. Long-tube headers were put on during this interval. This is API SL rated Royal Purple. He may try Amsoil XL 5w-30 next time. This truck is used to haul a lot of various supplies to construction jobs, heavy tile, etc. Steady diet of E-85 fuel still as well.
