Hey all, I just picked up a 1997 e350 short bus with a reman 2001 7.3. I've heard that the oil pressure gauge is an "idiot light" but that it usually registers dead center when there is any oil pressure. My gauge is topped out from the moment I start the engine 'til I shut it down. Any clues on...

Does anyone know about the John Deere Plus II 15w40 engine oil!? Is it cheap? Does it work well in summer/winter? Runs good? How many miles before you have to change!? Anyone know? Thanks! :icon_ford: :woot:
