I tried all sorts of oils in the 300CD.
Mobil1 5w-40 delvac 1
mobil1 15w-40 delvac 1300
Kendall 15w-40 (from the dealer)
Castrol 15W-40 (from the dealer)
didnt notice a single difference...
in the E420.. since it's had Castrol GTX (20W-50/10W-40) all its life.. it gets that...
the Celica gets whatever Jiffy Lube put in it (Pennzoil 5w-30).. ill change the oil myself this winter and throw in Castrol GTX/Mobil1 (10W-30) since they are easily available.
