EcoBoost Full Test

[Z71_Silvy]

Another fantastic test by pickuptrucks.com

I'll save everyone the searching. These figures are for a 3.55 equipped truck, crew cab, and 2WD. One had a 9K pound trailer attached.

Unloaded MPG - 20.80
Loaded MPG - 8.3

For a loose comparison's sake, here are the figures from the test of the 5.0...which had shorter rear gears, and a heavier curb weight. Trailer weight stayed the same.

Unloaded - 13-18MPG (in the LA area)
Loaded - 9.42MPG

Full article is a great read:

figures the mpg would suck. good find though

Wow that is interesting that they are that low during tow. Really not too surprised though.

thats what i was thinking under tow it's acting just like a regular v6 and being the turbo is probably producing a good bit of psi the whole time

Levine noted what I experienced on the second page, "noticeable turbo lag when unloaded". The engine hits max torque at 2500 rpm but it seems to take a second longer than normal to get there.

The comments people are tearing him apart for only running the test with 87 octane when ford's user manual recommends premium for heavy duty or hot towing applications. His response was Ford told him to use 87 and that he didn't have a user manual in the vehicle to find this information.

I wonder if it's a 'torque management' type of thing...

I doubt that would have any difference at all. Certainly not one big enough to write about...

I thought the 5.0 felt held back more by torque management than the eco.

Regarding the regular vs premium thing while towing - Levine mentions in the comments that he believes the ecoboost was running rich intentionally. This was done during the hot climbs to keep the engine cool. This would be minimized running higher octane.

I suppose. Either way, he is doing what Ford told him to...I can't fault him...his tests are in a league of their own.

I should have an eco-boost this week and can post my results too
