Well fall is here so I needed to get another winter/hunting rig. I ended up with a 2002 Ram Quad Cab that's clean for it's age. Overall I'm happy with it, except it has the notorious chrysler 4.7L power tech. Truck has a 160K and runs great other than being underpowered. Coming off a 5.3L Suburban it just feels underpowered, but it's fine for my needs. Anyway, given this engines reputation for all sorts of bad can someone point me to a good oil and a reasonable interval? I always thought it was a decent engine until I read up on it.
