I'm sure it's hard to prove an oil failure Deron,. but with that said your above post shows a bad design with the positioning of egr valve which cooked the oil away causing the problem, not from the breakdown of the oil or bad filtering. Like I said before these oil threads are always enlighting. Now whats Whistle using metzler 10w40 or michelins 20w50?
