Good, dad's and i's cars call 4 5w20 (mom's does 2 but because high milage i run 5w30). Prob should shake the bottle i think it's been in the garage for about a yr.
How old is the mobil 1 leftover? Is it the trisynthetic formula? That is REAL synthetic. Most everything else made today they are fibbing about it being "synthetic" ('ceptin the RDS stuff).
