I'm thinking about running a 4,000 mile interval of BradPenn 5w-30 in my GF's Mercury Mountaineer. This oil is cheap so I'll do a "Patman Flush" of dumping the oil, filling it with Brad Penn, running it for a few minutes, dumping it again, and refilling it. I was gonna switch her over to Bobzoil, but have been interested in this locally manufactured oil for a while. If anybody else wants to see it, I'll do a VOA & a UOA @ 4,000 miles before going to Schaeffer's. If nobody is interested I'll just go with Schaeffer's.
