E85 will get worse mileage than gas. All it's good for is less pollution and a tiny bit more power

 

exactly what makes me question if there's something wrong. 4wd should use more gas too, but it doesn't.

E85 I just reset the display though, didnt do a full tank so didnt hand calculate.

 

my dash says 11.4 right now. Leveled with 34.5" tires but still even when I was stock I think it was around this, maybe a single MPG better. I do drive it like a racecar though so yeahhh. No issues so far, love the truck to death!

 

yeah im pretty heavy on the peddle too lol. Probably the main cause of it, since everything else is stock.

 

My late build 2013 FX4 5.0 had a cold engine knock at 25,000 miles, the engine was rebuilt. Cylinder #8 was oblong and caused piston slap, fairly common concern with some being more severe than others. Mine was severe enough to cause low compression on cylinder #8.

 

Same as his but mine was cly #6 and it wqs short block at 25.5k miles. Herd ot was maily 3&4 cly. But thats been skewed now

 

My truck has 52,000 the pulleys sound like one is worn out
has a small oil leak from some where
timing chain sounds like it is going to fly out when I crank it in the morning
and I can here some what of a knock I can hear when I'm beside something

 

Leaking 3rd brake light
Leaking moon roof
Engine knock
shattering rear window when defrost used
squealing brakes
Slip bump clunk-re grease drive line
Orings leak anti freeze from y hose - degas bottle leak

 

Are you saying the knocking was not there at normal operating temp? Ive had a cold knock since new that goes away and turns into a perfect sounding purr when its up to temp. I was told the steel/aluminum tolerances are shifting during the warmup phase and it resolves itself when fully up to temp, and there's no problem. Mine runs great at 40k now and I've had no issues with it.

 

Only issue I’ve had is fuel pump fuse #27 had to be relocated. Other than that no issues 82,000 miles
