I just got a full size dodge, with a 4.7 liter engine. It doesn't do too bad in the mileage department for a full size (quad cab, 8 foot bed) , seems to get 12.5 -13 combined.
I was wondering what oil I should use? is there any that would be safe and give me better mileage? what about Amsoil 0-something? I am not discouraged by the cost, if I can really leave it in 25000 miles.
Would I need to change it sooner if I towed the Cobra with it?
