i have 5 quarts of the following 3 oils, all possible choices for my Auto-Rx rinse phase:
Quaker State
Mobil Clean 5000
Exxon Superflo
i just want to know which one is best for cold weather. the car previously had Lubro-Moly 5W-40 synthetic in it, then i dumped it and put in mobil clean 5000 5W-30 + Auto-Rx for the cleaning phase. since then, the car has felt alot crappier, i must say. the plan is to get this Auto-Rx thing done with, so i can get the car back on a synthetic. probably syntec 0W-30 or mobil1 5W-30. at this point i just wanna know which of the 3 dinos i have in stock to use for my rinse phase.
