I'm one of the lucky ones and was able to squeeze out 45K miles from the factory Continental ProContact TX tires. Honestly, they should have been replace a little sooner, but here I am. Alive. Posting this update.
Anyways, I posted a detailed fuel economy review for the past two years here...
I guess I'll add my first two years of ownership to this forum. I really don't have much to add to what's already been said, but I did keep somewhat meticulous notes on my fuel economy the past two years; so I may or may not have that going for me on this post.
I had my truck delivered to me...
I had a 2012 F150 with 3.5L Eco. Around 175,000 miles I finally started to get the infamous rattle at start up which was common on the those very early 3.5. I had been on the road and wasn't keeping up with the service as best as I should.
Next got a 2016 F150 with 2.7L Eco. Great engine...
