Just ran across this. We've all debated about this engine and now it looks promising from an MPG standpoint. This is in the Lincoln MKS but I wonder how it will do in the trucks. I guess time will tell.

Ford details how EcoBoost will be more powerful, eco-friendly than competition

 

It'll take a lot of time to tell how they *really* do, like when we have 15 year old EcoBoost trucks being run on the cheapest gas possible, overloaded, low on oil, etc, by lawn crews.

I just don't think there will be a long-term payoff in total cost of ownership on the EcoBoost once the cost of repairs is figured in. I don't see these as 200k-300k mile engines, which I consider the modular motors to be without much trouble at all.

I don't see any of Fords engine being 200 or 300 K engines other than a diesel.

 

the 5.4 is easily a 200K+ motor....

 

I have a buddy with a limo company running stretched and regular Town Cars up well over that regularly. Look at all the cop cars in the world, recycled into taxicabs after their police duty.

There are certainly a small number of any engine that die prematurely, but I'd say the mod motors in general are as long-lived as most anything out there.

25mpg in a MKS. I am actually a little disappointed by that. Because, if it gets 25 in a car, I would think you will be lucky to get 21-22 in a F-150. The 4.6 3v can do that. Hopefully it will do better than I am thinking. Maybe there will be a significant difference in city fuel mileage.

 

So this engine will require premium correct? And if it does then I just can't see why anyone would choose this engine over the 4.6l 3v that runs on regular.

 

Nope...regular unleaded.....and i'd be happy with 22 in a 4wd F-150.....

 

Really!? That surprises me, you'd think it would need premium since it runs a little cooler and these engines I imagine create a lot of heat. Well thats good then! Maybe this engine will be a hit after all.

 

I think that was a main design feature of them....that they ran on regular...

 

still...it's a small motor running a decent amount of boost in a 5,000 to 6,000 lb truck...and it will be severely taxed with towing/hauling


I cannot see the ecoboost being a good option for the F-150. I can foresee it being an option for 1-2 yrs, then getting dumped once the reliability issues come to light as it is used as a TRUCK ENGINE...and not a MPG gimmick

 

Thing is the EB won't feel underpowered compared to the the 4.6L. so not a fair comparison.

 

Cylinder displacement has nothing to do with structural integrity of the engine and its components. If it's an 8L made of aluminum, it's not going to be as tough as a 500cc engine made of titanium.

 

OK, Which engines on the road do you consider 200-300K engines? If you don't think a Ford gasser will make that lofty goal, then why are shopping for a Ford truck?

Not crackin' yer onions, just curious.

Talking about MPG's, the Ford website says the Flex with the 3.5L EB is rated at 22mpg's HWY. Lots of power, not great mileage.

It's exactly the same as a Flex AWD with 3.5 with no EcoBoost. Constant AWD sucks up a bit of that juice, just look at the Durango, that you can't switch to 2wd. It's worse than the larger Expedition.
