I ran mine with Mobil 1, 10W-30 and it's now at 260,000 miles, running perfectly. Company trucks had the same engine, and some made it 900,000 miles of delivery work. 4 transmissions, one engine!
Model years?
My buddy had what i think was a 2009 or 2010 F150 i forget, but it had pull like my former GF's 2003 Suburban.
Both of these vehicles had power for days. And both could power out of turns like you wouldnt believe, if you got on the throttle.
