Hard to believe that in only 2 years and 8 months, I have managed to roll 100,000 miles on my FX4, but here we are. A few thoughts about the first 100K:
It has had 116 quarts of oil run through the 5.4L engine with 68% of it being synthetic (Pennzoil Ultra 5W-20) and 32% of conventional (Mobil Super 5000 5W-20). It has only had 5W-20 in it as designed by the Ford engineers, 5W-20 has caused ZERO issues with the engine even when towing in 100+ heat for extended times and the UOAs reflect stellar performance. It has had 16 Motorcraft, FL-820s oil filters installed as well as 2 Motorcraft and 1 Napa Gold air filters. It has averaged 16.8MPG which equates to 5,952 gallons of fuel with 92% of it being E10 (87 octane) and 8% being E85 (106 octane).
It has towed at least 45,000 of the 100K miles meaning that it has been used as a truck about 45% of the time and is likely more than many of the trucks on the road today average. The transmission, transfer case, front and rear axles have had their fluid (and filter where applicable) changed two times and the power steering and brake fluid has been changed once. It has had two sets of tires; the OEM Pirelli Scorpions which lasted about 51,000 miles and Michelin LTX MS/2 which now have 49,000 on them and appear to have nearly 65% more life in them.
It has had a set of brakes installed (front only), but a problem with the driver’s front caused the Wagner TQs to wear out and thus a new set of Ford rotors and pads were installed. The rear brakes still have plenty of pad material left and the brakes have very good stopping power.
Mechanically, the only issues have been the rear main seal had to be changed at about 16,600 miles as it was installed incorrectly at the factory. The other thing that failed was a fan relay at about 98,500 miles. Other than that, nothing else has caused any problems. The sparkplugs, serpentine belt, and coolant will all be changed shortly.
All in all for this first 100,000 miles, it has been a great truck and am looking forward to the next 100K (and well beyond that).
