Someone who will remained unnamed accidentlly picked up the wrong oil for me. I asked them to pick up 5 qts of Mobil 1 Synthetic Oil 10w30. Here's my problem, this person got me Mobil 1 Synthetic 0w30( yes that's right 0w30 ). It says it is an extreme formula that protects from 400 F to 50 F below freezing. Do you think this is worth trying in the engine or should I take it back and get 10w30?? VERY VERY CURIOUS!!!
