been running svo for nearly two years now (Veggiestroke - Classic Series) ...this is my latest report from Blackstone...oil is changed every 5K.
"
Wear is as good as we've been seeing so there were no changes this time that would suggest any new problems for
this 7.3L Power Stroke in your F-250. Wear metals are slowly creeping up from what we were seeing back
in 2007, but at this rate, your engine is still on track to have a very long life. "How long?" you may ask. We
would not be surprised to see it easily last 300,000 miles and possibly a lot longer than that. Still no
anti-freeze or excess soot present. Nice report."
