What grade of gas to put in 4.7 V8 on 06 dodge ram?
The 2006 Dodge Ram 1500 with the 4.7L V8 engine calls for regular unleaded gasoline (87 octane). The owner's manual will explicitly state this. While using higher octane fuel won't hurt the engine, it's unnecessary and a waste of money as the engine isn't designed to take advantage of it.
