Not bad. I know there is definitely a break-in period on these trucks. It was the same with my 08 Daytona.. I am at 4000km and still getting just 14L/100km (16.8mpg).. I have swapped my PCM and installed a diablosport tune.. so that 14L/100km is on 87 octane fuel though.. I expect that once break-in is completed I will see somewhere around 12L/100km (~ 20mpg)..I was averaging 15.7 my first 3k miles. I'm now averaging 17.8. Went up a bit. I live on the edge of a small town, some town and some country driving.
I did a road trip this week. Got 21mpg on country roads with semi-frequent stops and avg speed limits of 45.
It's not about mpgs, it's about getting the advertised mpgs, as you said. The mpgs on the V8 Rebels are generally lower than the other 1500s despite the same advertised range, and for obvious reasons (LT tires, lift). Plenty of threads about this, but not much anyone can do.Yes I understand. I had an 05 f150 lariat v8 and full economy was not great and when i raised it and stacked it with wheels as we have on our Rebels. The mpg when south real fast. I was hitting 9 mpg so i can understand that, however, RAM is advertising different numbers with this setup and I am not seeing it so that is what i find confusing. Perhaps the motor still needs to break-in. Let us see what happens.
