I remember reading an editorial in a motorcycle magazine about 4 cylinder bike pistons typically travel about 1/5 of the distance in the bore of the odometer reading. I figured I'd ask Grok to do the same calculation for my 2016 5.0 F150: 242,500 miles, 6721 engine hours, 1277 idle hours, stock height tires, and 3.55:1 gears. It said 65,000-66,000 linear miles on each piston (7.3" every stroke). It also figured 629 revolutions per mile, almost 600,000,000 total engine revolutions, and 300,000,000 valve openings/closings on each valve. Each piston has likely traveled about 1/4 of the distance the truck has. I'm hoping to get another 25,000 miles on the pistons of this truck.
