Diesel MPG and fuel additives
I recently purchased a RAM 3500 DRW with a 3.73 rear and ASIAN transmission. I am not using any fuel additive at this time. I only get about 14-15 MPG not towing at 65 on level ground and about 7-8 MP...

First, read the owners manual. I'll bet there's a spot in there where they say not to use any additives in the fuel.
Second, I will never believe that adding anything to your fuel will boost mpg enough to pay for the additive - snake oil.
Lastly, the 850 lbs-ft of the tq the new diesels make, and the emissions garbage they are saddled with decrease their mpg. The 5.9L Cummins won't be matched for it's mpg and power combination with the power war and new emissions laws the new diesel engines have to deal with. It is what it is. JMHO.
Actually, there is a "spot" in the fords manual that says"Diesel fuel conditioner
Additives that will improve fuel cetane numbers may be used to
verify/enhance fuel quality. Use Motorcraft or an equivalent cetane
booster & performance improver as listed in the Maintenance product
specifications and capacities section in this chapter."
The OP owns a Cummins not a Ford. There is a difference in maintenance, operating costs and recommendations like I mentioned in another thread. All diesels are not the same.
