My daily driver is a 1988 F-150 with an unknown # of miles on it.

If it has the 4.9L inline 6 you could get half a million miles or more. That was the best internal combustion engine ever conceived by man.

I had a F-250 with an inline 6 that I bought brand new in 1988 and sold it 10 years ago with over 185,000 miles on it. I third owner is still driving it.

I would say the Ford 170-200 ci inline 6 from the mid 1960’s is the second best.
