Hi

We have about 80,000 miles on the Montana and all but about 3,000 of that on G614s.

The truck was new when we change to the G614 and still getting 6 to 7 miles to the gallon. At about 30,000 on the truck our mileage started improving rapidly.

We now average 12 MPG on the highway with the Montana at 60 MPH and 18 MPG on the highway bobtail at 75 MPH.

I haven’t found any difference in mileage between winter diesel and summer diesel. The Cetaine in diesel doesn’t change like the Octane in winter gasoline.

I find this compares closely with most of the folks here on the forum.
