Sample from my 2013 F150. This run had a 1400 mile high speed (80 mph, legal in WY), high altitude (2500' - 6000') round trip, and an additional 1500 miles towing a 5500# trailer at legal speeds up to 75mph. (Please save me the scolding for towing fast, the trailer was loaded correctly, stable, and well under the truck's maximum)
I'm really impressed with the UOA, the Schaeffer showed very low wear and held up well. I'll be interested in comparing to Amsoil on the next run.
Lastly this is part of my thick vs thin test, so there will also be 0w40 and 5w20 runs...stay tuned for those threads as they happen.
