mobil delvac 15 40 diesel oil and wix filters! it was fine in oil consumption until that night when it started puking oil thru breather dump tube! I mean it pukes it and it pukes it a lot. I would say a qt in 20 seconds of half to full throttle. its bad, something is wrong and im afraid it might be the worst case!
last time I started it I have it some throttle and something started to make noise, like a machine gun fire type of racket! I shut it off, looked at huge puddle of oil and left it like that.
