Ive got some 2007 vintage mobil 1 5w30 quarts in an outdoor shed that have turned kinda red like old transmission fluid. The old caravan hasnt complained
"anotheroldguy" hasn't been back on for over four years, hopefully he figured it out by now.Old oil is fine, but it may have a plastic taste from the bottle leaching out.
I would have asked Pens, if its ok to tell everyone that their oil go's bad in four years. and what exactly has gone bad in the oil??
Total BS on there part(Imo).
