- Hey guys, this question has been asked alot, and im a young truck enthusiast, at 25 ive only had a couple, but to be honest ive been a chevy guy a while and its time to put my old 1500 5.3 to rest. That said i have a good family friend with a 2011 f150 4x4 ecoboost with only 30,000 miles on it. The guys willing to sell it to me for 12k witch to me is a steal, but iv read so much bad **** goin on with these engines and this beimg one of the first ecoboost made makes me concerned, have alot of you really had that many issues with these? Even with stellar maintence? I change my oil every 3000 miles, i always try to overkill it, cause i can break anything haha.
