I'm about to change the oil in my truck, bought some Royal Purple as Wal-Mart was out of 5-quart jugs of Mobil1. I also bought a Supertech filter as those and Fram are the only ones carried by the chain now. I heard some good stuff about Supertech awhile back and know they are better than Fram. That said, I'm about to go buy a funnel, so I think I will invest in a Mobil1 or other filter. No sense putting over $30 worth of oil into the truck with a $2.50 filter.
