Re: Maruti Eeco Engine oil Dilemma.
1100? out here in mumbai you get 0w40 for 800 without bill and rs 950with bill from their dealers.
you also can get 5w30 in mobil1 I've been trying to find that but audi takes it up.
you could also give mobil 10w30 a try its a great oil.
however if maruti has been filling a "x" w30 oil in your engine all this while i think you should stay with the with that cause if you move up to a 0w40/5w40 fuel economy will give down, depending on the engine very tiny bit to a fair bit.
my engine has recommendations for a 5w20/5w30 for fuel economy.
by the way api-sn is the current standard go in for that its way better mobil1 has api-sn
