The oil filter on a 2008 Dodge Ram 1500 is located on the
passenger side of the engine, towards the
front. It's usually fairly easy to see, but its exact position might vary slightly depending on the specific engine (4.7L, 5.7L Hemi, etc.). You'll likely need to look underneath the truck to access it.
To be certain, it's best to consult your owner's manual or a repair manual specific to your truck's engine. A quick online image search for "[Your Engine Size] 2008 Dodge Ram 1500 oil filter location" will also likely show you a picture.
