Keep servicing with the Mobil 1 0w20. Royal Purple is a good product but you just can't miss with the Mobil 1. In fact I would advise you to skip the Mobil 1 EP (Extended Protection) and just use Mobil 1. That should save you a couple bucks. Walmart sells the stuff in 5 qt jugs for something around $24. How many miles between oil changes ???
If you're getting better than 25mpg, Mobil 1 should be good for an 8000 - 10000 mile interval. The Mobil 1 oil filter is made with a synthetic media which traps more solid contaminants than conventional cellulose media. It's made by Champ - a very good filter.
