I have a 2011 5.4 3v that’s approaching 180k miles with no indication that it needs a timing job either. I followed FordTechMakuloco‘s advice and switched to 5w 30 full synthetic at about the 90k mileage mark
Yeah I was hoping to go a little more on them but it might be something to consider. But at the same time like I said it runs great. Idles smooth and acceleration hasn’t changed at all so I’m not sure
2011 XLT current mileage 173,000
I purchased my 2011 five years ago with 90,000 miles on it. Ever since then my MPG consistently sat around 17 with my daily mix highway/in town driving. In the last month I’ve seen a decline in mpg to 15.8 with no change in driving patterns . Air filter is clean...
2011 with 162k miles with original parts and no noise. Purchased at 89k and use 5w30 full synthetic at 3,500 intervals ever since. Original owner did 5k oil change intervals and was using motorcraft 5w20 blend.
