104k miles on my lowly 5.4L F250. First truck I’ve owned in a long time that I’m not itching to trade off.
I have had three 5.4l's . One 2 valve and 2 3 valve engines. Combined 500,000 on the three trucks and very few problems with them. A much better engine than the internet scholars would have you believe....
My understanding is the 3 valve with the cam phaser requires clean oil for longevity. I have a 06 Ford 5.4 with the cam phasers. The other thing is keeping the coolant changed so the dissimilar metals don't start eating away.
On FTE there are quite a few people with a lot of miles on the 5.4 engine.
