Hello, I have a 2022 2500 with a 6.4. I'm chasing my fuel milage all over the place from 14 to 21MPG. It doesn't matter what grade of fuel I run in it 87 or 93, I feel no engine miss or stumble in it, it gets up and runs down the highway and tows our 34' travel trailer 10 MPG at 60 MPH with no issues. I only have 10,000 miles on it, any help would be greatly appreciated.
