Hi guys, curious what you guys are getting with our gas in our conditions. I put a new motor in my truck and although it runs great, I'm getting terrible fuel economy especially on the higbway - 16.5L/100km at 105km/h cruising. This is on 91 shell. I'm driving it less just due to the excessive fuel consumption. What are you guys getting? My truck is levelled on 285/60/20 duratracs and has pocket ported heads on the new forged shortblock.

Ecoboost crewcab/5.5ft box with 4x4 and 3.55 rear end.
Did a run up to the cabin about a month ago in SK (500km round trip) and averaged about 14L/100km at between 110 and 120 km/h using Shell 87. Temperature was around -15*C
Same drive this past summer netted me about 12L/100km just for comparison sake.

Mine is a first gen 2012, you guys too?

UnkLeRaRa

First gen? If it's a 2012 it's a 12th gen, lol.

I have an '18 (13th gen) with the 2.7

Is yours a 5.0 or a 3.5 EB?

It's a 1st gen EcoBoost.

So pretty bad, like mine. I'm levelled with bigger tires though.

When it was brand new and bone stock I could get 11-12l/100km at 115km/h in the summer.

Best ive ever seen is 12.3/100
taller and heavier tires hurt, so does winter gas..usually in the 13's in summer with stock tires

18 5.0 10speed 331 4x4 screw, mid to high 11's in summer low 13's/100km for winter blend. Life time average of 12.4L/100km wich includes burnouts, donuts and the few times she's seen the speed limiter lol . Truck only has about 7000km on so far tho. Basically bone stock except for AEM dry flow drop in filter. I do however remote start and idel for atleast 10 min 2X a day mon to fri during winter which might explain the bigger gap from summer to winter gas. Also 90% city driving dont help.
