Assuming the vehicle doesnt use synthetic oil what type motor oil should I use for a 04 Mercury Presidential?

what it says in your owner's manual, in the glovebox


seriously, doesn't anyone read this thing?Assuming the vehicle doesnt use synthetic oil what type motor oil should I use for a 04 Mercury Presidential?
5-W-30 just like the book says.Assuming the vehicle doesnt use synthetic oil what type motor oil should I use for a 04 Mercury Presidential?
manual will tell you but probably 5w-20
most new fords/ mercury vehicles require 5w20 motor oil. check on your oil fill cap, under the hood. it will tell u what oil weight to use. as far as brand, that is mostly a matter of preference. I prefer castrol.
i like 10 w 30 castrol oile

say yes
