    2018 Big Horn thoughts at 30,000kms.

    I picked my truck up last October and it just rolled 30,000kms. The truck is super smooth and quiet. I put the GDE hot tune in at 1,800kms and I have never seen anything above 8L/100kms even in the winter. I usually get around 7.2- 7.3l/100 in the summer. I have had to add 4 jugs of DEF fluid in the 30,000kms. I bought this truck for the mileage as I own a pest control company and I drive a lot. I just completed my route today which consists of mostly back roads with 25kms of highway and the evic is showing 6.5l/100kms which is 36mpg us or 43 imperial. I've had zero issues with the truck. I'm going to send my next oil change out for analysis just for peace of mind. I'm super happy with my purchase, thanks to all who post in this forum. Without you I probably would have just bought a Hemi.

    ...and you were smart. You did the GDE tune and are running clean.

    Thanks for posting about such a wonderful experience.

    And consider the GDE Tranny tune sooner than later. I waited till I had 183000kms on mine and wished I'd done it sooner.

    Must be 3.55 gears to achieve that fuel mielage. Also must be driven in flat terrain. Still impressive.

    Realistically there's only about 1mpg difference between 3.55 and 3.92. The ratios are closer together than you might think.

    I just completed a trip from IL to NC and back. Some of my best mileage was in the mountains of WV.

    My trip was the opposite direction of yours. NC to Iowa and back. Best mileage I got was on flat state and county roads keeping the speed between 60 and 65. South Bend, IN to Columbus, OH. Hit 27 mpg on that tank. Next best tank was last year from Lexington to Charlotte. In and out of the mountains got me 26.8. 3.92 gearing and all stock.

    Those are exceptional numbers Chiaj.
    What part of Ontario are you driving? I can't get near those numbers around the GTA.

    the EVIC also says the average speed for that " 6.5 L/100Km stretch " was 53 kmh , ( 32.9327 MPH )
    no wind resistence at those speeds , gotta love the economy , I often see 5L/100KM on EVIC
    doing 103KMH on highway ( 64 MPH ) , in the summer , --> tuned .

    Chiaj144, is that hand calculated? Or straight from the optimistic trip computer?
