Trail Boss MPG Competition

[ShamrockShooter]

 

Alright who can do better than this for 100 mile trip or longer? No cheating by coasting down a mountain with the wind at your back.

 

Why? Because it makes perfect sense to have an MPG Competition with a lifted truck running mud tires.

My best 50 mile average is 23.5mpg

These numbers are pretty good for a Trail Boss setup. Especially considering your truck's powertrain is still breaking in. It should continue to improve as time goes on.

It would be more impressive it this were hand calculated averages instead 'happy' ECU numbers. Right?

Not a Trailboss, and not lifted, but when my 2016 5.3 Max tow got less than 20 for a tank average I was disappointed. 

Of course when towing it was a much different story.

Great mpg, what was your average speed, 65?

[UGADawgs]

I do 65 in my driveway ???

Usually go about 67 to 68 cruise, knocked it back to 65 for traffic right before I got off. Concrete expressway. 50 degrees, 10 mph crosswind.

That included 5 minutes in the drive thru at Dunkin or it would have been over 22 mpg for 100 mile trip.

My first two tanks have been hand calc within 0.1 mpg of computer. This truck is dead on so far.

The 19’s seem to be pretty much dead on as compared to the K2’s.

I've been using the fuelly app to record fill ups since I purchased the truck, interesting to look at the graphs it provides. Lifetime is sitting at around 20. Interestingly, the guess-o-meter in the truck is about the same.

[ShamrockShooter]

I use the TFL truck method. Fill till it clicks, wait 15 to 30 seconds then fill it till it clicks a second time. If this truck keeps being dead on with the meter after a few more I won't bother hand calc anymore.

Wrong, not “happy” numbers at all. I’ve hand calculated a number of tanks on this rig, biggest disparity was still less than 2% off. Last tank I did, the DIC was actually reporting a tenth LOWER than the truck got.

 

This is exactly the same as what I’ve heard from every single other 2019 owner who has compared the MPGs on the DIC to “real life”.

I've done better but this is the only picture I have. Stock trail boss with the 18" duratracs.
