I'm Awesome
Well, a quart every 3 thousand miles with 300,000 miles ain't exactly awful. Sounds like he followed a good maintenance routine with the vehicle. The dino oil sure did the job, no question. On the other hand, the synthetic is obviously either going down the valve guides, or past the rings, not unusual after 300,000 miles. Maybe, the lube is getting to the right places?
Finally, wondering why he changed lubes after such a good result.
