2013/ 5.0

1300 miles getting 19.7 on pretty flat highways runs in Texas

 

To the tetra meth dick I get 11 mpg with my 12 ecoboost. 373,fx4, 35x12.5x17. And that's driving mildly

 

Damn man, i don't feel bad averaging 13.5 the last 10k miles in my 2013 5.0 driving mildly.

 

Been doing a bit more hwy the past month




2011 Eco, 3:31

 

Drove 132.4 miles today in 1:57 minutes and used 6.9 gallons. I believe that equates to what, 88 mph give or take some change? I avg. 18.9 at the end of the trip according to the computer, but the calculator comes up with 19.18.

Had to go through a few small towns whereminhad to slow down. Also, went through a couple wining steep canyon passes that slowed me a bit. Gained about 2,500ft in elevation. And lastly, I do have to go through a pretty strong windy corridor.

I drive this twice every weekend.

Pretty sure I did the math right on this, but feel free to correc me if I am wrong. Math isn't my best subject.

2013 XLT Supercrew ecoboost, 4x4, 3.73, stock wheels/tires w/ approx 6,300 miles total miles on the engine and no performance mods to date.

Life time mpg is not as good, but neither was my mpg period to start with. I feel the engine is really breaking in now and beginning to see the better mpg. I also was hitting WOT a lot when I first got it. I justified it by claiming I was breaking her in properly, but we all know it was cause the turbos just beg to be ran hard lol.

 

I believe you better check your watch!!!!

 

I know the miles, time, and gallons used are correct. Did I go wrong somewhere else with my math? I really am bad at it lol.

 

67,000 miles never been to the shop except for oil changes

Most trips I average 21 to 22 mpg. 1 trip of a 1,000 miles (Wichita ks to Atlanta Ga) 23.8 mpg.

Trip from Wichita, Ks to Detroit, Mi 23.8 mpg

3.15 gear ratio with Hankook P235-75r17 nitrogen filled tires.

A friend bought new rims and tires for his 4X4 SCB XLT so since my tires had 65,000 and look like I could get another 10 out them I decided to buy his rims and tires.

P275-65r18 no nitrogen

 

I went the dual muffler route (got it free but that is another story)....... No change in sound to mention, no increase in mileage. No noticeable difference except they look good. Don't waste your money ($800) and you won't see any return.

 

I set a new short run record tonight !

Top of the Cochrane hill to Panorama Hills (Calgary) - run of 32 km, drove it 90km/hr the whole way in medium rain. Zero'd my Scan gauge and Truck MPG - result :
*not sure if the cooler air was a little more dense and helped the motor. Also - his tank has been a 91 octane tank - the truck REALLY likes the rich stuff.
