This was my first analysis for my new-to-me 1995 F250 7.3L Powerstroke. The truck had 70K miles on it when I got it last December. Changed the oil at 75K miles. Analysis by Blackstone.

"It looks like the Tractor Supply Traveller All-Fleet 15W/40 oil is working quite well inside your 7.3L
Power Stroke at 76,000 engine miles. There was, however, 2.0% fuel dilution in the oil, which likely caused
the viscosity to read a little low. This is a borderline acceptable amount of fuel, so watch for increased oil on
your dipstick. If you oil level increases, you may have a fuel system problem. Universal averages for this
type of diesel are based on about 5,500 miles on the oil. Your engine wear looks good after 5,000 miles on
the oil. Try 6,000 miles next and we'll watch for fuel."
I'll be doing my 2nd oil change and analysis later this week. I will be paying particular attention to the fuel%.
