I have a work truck I drive that has 255k on its 5.4 ...untouched so far except normal maint.
This was a HUGE deciding factor when I chose an Expedition over a Suburban. I do think the 350 Chevy engine will run 200k miles but those 95-99 versions I was looking at usually need a tranny right on cue at 100k miles. The 4r100 behind the 5.4 in my 99 Expy is similar to the ones behind the Super Duty trucks. I definately have more drivetrain than I need, I like it that way.

177K on an 04 4.6 E250, 172K on a 00 5.4 Expy. They both run extremely well. No major problems and routine maintenance. I run Max Life oil and change every 5K. They run like they day they were new. Honestly. Gas mileage has not changed. I have replaced the plugs in the 5.4 but that's it. I think I will do the 4.6 plugs this winter. No plans to get anything new. Just keep driving them. Great friggin motors.

What motor oil are you using? While mine was under warranty I let the dealership do the oil changes, and of course they use the Motorcraft semi-syn. I used (not leaked) about a quart per interval then. Now that it is out of warranty, my trusty old mechanic does all the maintenance. He keeps conventional Chevron Supreme or Havoline on the shelf and usually uses the Chevron. Since then the oil level shows on the dipstick at the same level throughout the entire oil change interval.

And let me throw this out there for everyone to answer (Yes, I am bashing Chevy/GMC). How many GM trucks w/350CI V-8s have you seen with around 100,000 miles (or more) on the odometer for sale...and one of the "selling points" is a new engine or tranny was recently dropped in? That tells me all I need to know about those trucks, as well as my own personal experience when I jumped on the Z-71 bandwagon a few years ago and had some issues with the "almighty 350".
I bought this '10 Ford to replace my '86 Chevrolet P/U with 230K miles, original engine and transmission without rebuild and ran fine. I sold it because the cab was falling apart because of rust. I'm a Chevy guy. The only reason I bought a Ford was because Ford offered a manual transmission and I wanted to shift my own gears, having a blast double clutching while downshifting like the old big rigs. I'm counting on the rest of the truck to hold up like my Chevys do.
