I am in the process of tearing down my 1995 Ford Ranger with 270,000 miles on it. I have used M1 10W30 since 75,000 miles when I bought the truck. I run 10,000 miles between oil changes. A bolt fell through the intake and cracked a piston is the reason I am tearing it down.
Does this have any value to see a high mileage engine as opposed to looking at oil analysis? So far the cam looks good and the cross hatch on the cylinder is still visible with little wear. The valve stems show almost no wear. If there is an interest, I can document in more detail as I progress through the tear down process. The engine is run hard at high RPM's going 80-85 MPH on the way to work everyday. I was impressed with the lack of wear. I have had the truck since about the year 2000.
