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.
