Exhaust Cleaning Bites
By RH on
2008 Ford F-250 Super Duty XL 4dr Crew Cab SB (5.4L 8cyl 6M)
I do a lot of pulling and highway miles. I love the power the 6.4 has, but I am not a fan of the exhaust cleaning. Drags your MPG down. If you regulate your speed by the turbo, (less than 10 psi), you will maximize MPG. At 50,000 miles, average highway is running at 16.2 pulling around 8,000 lbs.
Trailer brakes, navigation, 6.4 twins
Seats could be better, No exhaust cleaning cycle, 38 gallon tank on SB
