Mine is a 16 3.5L eco, and average around 12 L/100km.... thats around 19 - 20 mph combined city/hwy. I should point out that I rarely ever speed beyond 105 kph and majority is hwy with very little city as I live close to a hwy. Pic says the rest. My head will explode from seeing such numbers as truck is still new. My hemi 5.7 ram barely got 15 mpg with same conditions. I will be doing more accurate test using full tank, drive 100 km, fill again and calculate, for me to believe it.

 

Is that a 4wd? Which engine and gear ratio?

 

4wd, 3.5L ecoboost, 3.55

 

You bought a truck wanting better fuel milage.
Ya put bigger tires v on b wanting better fuel milage.
Why.
That is what cars are for.

 

Not sure who you are replying to. The 20 inch wheels and kankook tires are factory installed.

 

 

Still looking for what to expect if I buy this truck. Constructive answers would be best.

 

my apologies, I should add that my numbers are based on 22" oem wheels... not sure how much that will differ with 20" wheels that you are looking to get. Hope that helps.

 

OK my truck (see sig) weighs about 6,000 lb empty and on the highway gets near 20 mpg at 65. At 75 more like 17. Gets about 16-17 around town. I tow very little so don't have an good idea of towing mpg. It would depend highly on what you are towing and how fast. I live in the DFW area so near sea level and pretty flat. I have the 3.73 LSD.

 

When anybody is talking about fuel milage on vehicles.
Has anybody looked at rolling resistance on tires..less rolling resistance helps fuel milage to a small extent.
