I have a RAM 1500 on factory order, expected to arrive in a month or 2. The truck will have the 3 liter hurricane. Thinking of dumping the factory fill at about 1000 miles and filling with PUP or mobil 1 ESP in the 0w-20 variety. Plan on using the truck's OLM to determine drain interval. I saw that my Walmart has Mopar filters so maybe they stock one that fits the hurricane I need to read up on filters before committing to one.
