Right about 82k on my '05. Car still feels and sounds like new. Running a CAI with a Diablo Tune. Been using Amsoil right now have 0W-20 Mobil 1 in it. I'm also an avid believer in an additive, "Tufoil" which I've been using for a good twenty-five to thirty years. Been keeping the fuel filter and 5 Speed ATF changed out on schedule. Other than that have had no issues. I did have the pinion seal replaced, and the fuel pump was changed under warranty.

As of last Friday, 3-9-2018, 323,000 miles on the2006 GT, 4.6, then, later in the day it appears she spun a rod bearing on number 2 cylinder. Hopefully we can confirm it later this week and make a decision on a new engine. When we pulled off the valve covers to check out the cams, chains and roller followers, everything was still super clean. Oil and filter changes every 2500 to 3000 miles with Motorcraft oil and filter. She just got tired. But, we'll get her back on the road. At age 70, swapping engines is a little tougher, but my son will carry most of the load this time.

08 GT auto with 87K and a remanufacturered transmission with about 2K on it. Regular oil changes at 5K with full synthetic starting at 30K, replaced the crap two piece plugs at 10K (and on my second set of one-piece now) and regular fluid and filter changes.
Zero leaks.

Had an '06 GT and it had 186k on it when I traded it in a couple years ago. Ran like new, no oil burning. Only issues were changing plugs(easily remedied by Lisle tool) and leather on doors coming unglued after 8 years, simple fix. Regular maintenance of oil/filter changes at 5k miles, 2 or 3 air filter changes, throttle body cleaned at 50k intervals, etc. By far, the best car in my 50 years of driving that I have bought new. Miss that car, was a fun car to drive.
