No. I use the Pennzoil high mileage oil, chnage it by the odometer every 3, 333 miles. I've been wondering if I can find someone local (Springfield, Va) who does oil analysis. Never done it before, but I'd assume they'd be able to tell me pretty easily if I've got coolant in there. Google hasn't really helped me find something...
