So I just spotted Mobil 1 0w30 and 0w-40 in walmart for $20. Im thinking its what Ill be doing my next oil change with.
I've got a 2007 volvo s40 and the manual recommends castrol 0w-30, Id imagine that is only because it would meet euro specifications.
I have never seen GC in my area, so im thinking the Mobil 1 0w-40 would be good enough (as its also euro formula). However the 0w30 would most likely save some gas and the car is speced for it.
Would 0w30 be a better idea?
