I feel like BMW probably has something to say about that. And Nissan.The 4.0L and the 4.9L Ford 300 I6 are probably the two best I6's ever built IMO.
Slash hit it right on the money. The Jeep I6 is the best NA I6 of all time. Reliability and usable torque around town. It's a tank that will survive a nuclear holocaust. It won't need to be babied like those Euro I6s. FPV's final version of the Barra 4.0 Turbo I6 is the best turbocharged I6 of all time and the best keep secret when it comes to engines. BMW, Nissan and Toyota can screw off compared to that engine.
Service is so subjective so I take that with a grain of salt. I guess it never had an oil change in about 2 years? It never had spark plugs changed? Then again if you don't drive it at all then I suppose you might get away with it. I made a habit repairing Euro engines. A Jeep AMC I6 will go 400k miles while being abused. It's the perfect car for the not mechanically inclined person. They will abuse it and not give it its proper service yet still run. The Euro will not do that on the whole. They aren't meant to so it isn't their fault. BMW is reliable for a European engine and a great performer but I'm far too aware of what they need. You have to baby them on the whole. It's the price you pay for the performance.Yeah cause the 2.5 litre six in my 24 year old car that had done 225k miles and hadn't been serviced in about 2 years really needed to be babied.
Same as our 2.5 litre 16 year old car with 175k on it and didn't go near a spanner in the entire time we owned it. Though we had to top the coolant up every 2 weeks.Yeah cause the 2.5 litre six in my 24 year old car that had done 225k miles and hadn't been serviced in about 2 years really needed to be babied.
The OP is wrong so there. We have that straightened out.It says turbo on the OP so that's why I thought.

They probably should have turbocharged it then - it'd only have 110hp crawling up Pikes Peak.From the lowest of sea levels to the highest. Climbing on mountains
So what you're saying is that despite it being rough as a bear's arse and getting terrible gas mileage, the engine's ability to survive crap maintenance and owners with no mechanical sympathy makes it the best I6 ever? Gotcha.That motor isn't turbocharged besides it is tuned for torque. AMC could not be arsed about horsepower. It was a work engine so it actually is a very stressed engine because it required reliability for a VERY long period of time under extreme conditions. From the hottest climates to the coldest. From the lowest of sea levels to the highest. Climbing on mountains to wading the sand. Jeep (well Wranglers and old school Cherokee) owners typically put their motors through more crap than any other vehicle's owners.
It won't need to be babied like those Euro I6s.
A poor attempt to beat the Land Rover Discovery.
I used to own a BMW E36 M3 Euro-spec (great car btw). Big whoop. I also owned a BMW E39 528i and it was a POS engine wise. The heat and salt where I live killed it. I replaced too many parts on it. The Vanos rattle to atrocious oil consumption. It didn't leak but burned it to hell. The hoses blew and the spark plugs went. Then finally the head gasket blew and the head was warped. I'm willing to say that mine was perhaps a dud though being a dealer car with proper inspection and paperwork. However, I worked on plenty of BMW I6s again that engine alone gave me a decent living. So YMMV. I've owned plenty of BMWs and they are my favorite European brand. However, you are quite lost at least on the Jeep if I'm honest.I used to own a BMW 328ci. I had it for three years, more than two of which it sat untouched, parked outside and subjected to Scottish wind, rain, snow and sub-zero temperatures. When I tried to start it after all that time, the only thing wrong was a flat battery. Other than that, it ran perfectly.
It also had three more bhp than that Jeep can muster from an engine 1207cc larger, and - I'm going out on a limb here - is more economical, too. I should make it clear that by no means is the 2.8 M52 engine the best I6 BMW has produced.
Those Euro I6s definitely need to be babied..
Thank goodness for torque.They probably should have turbocharged it then - it'd only have 110hp crawling up Pikes Peak.
Yes because I always wanted to have a vehicle which didn't require anything off schedule even topping the oil off. Just a beater to abuse and neglect without consequence. Oh wait I did in fact I owned a couple like that. It was my old hand me down Jeep Wrangler. I sold it to some kid after 353k miles (and I owned it after it just turned 101k). It never leaked or burned oil. It never smelled and the hoses never exploded or cracked even after its life as an off roader. The gaskets never blew and I upgraded the clutch for my personal preference. It was my shop's everyday get around. It also took long trips.So what you're saying is that despite it being rough as a bear's arse and getting terrible gas mileage, the engine's ability to survive crap maintenance and owners with no mechanical sympathy makes it the best I6 ever? Gotcha.
Sorry, I'll take the tuneful, powerful BMW unit and suffer the absolute anguish and pain having to... erm... top up the oil now and then.
Wait, that doesn't sound that bad at all.
And people have taken 300 I6's to 750k on nothing but oil changes and hard miles including drowning it under water. They put them in everything from trucks to UPS trucks to dump trucks because reliabiilty and low RPM torque. The AMC engine here is the same and the 225 /6 is high on the list as well. All are widely considered the best ever built when it comes to reliabilit and various ther attributes. Its not really disputed. Its not made to go fast.Yeah cause the 2.5 litre six in my 24 year old car that had done 225k miles and hadn't been serviced in about 2 years really needed to be babied.
