When I had my Ram 1500 with the 4.7L gas engine... I noticed that Kroger fuel typically provided me with the best MPG. (I log my fuel economy religiously with a spreadsheet).
Well, I've been filling the CRD at the local Murphy USA spot in town (Walmart) for the past several tanks and my mileage has consistently been 23-24 MPG. I'm consistently showing around 210 miles when I get to the half-tank mark (with GDE tune).
This past weekend, I found a Kroger that actually sold diesel fuel, so I stopped and filled up there. Yesterday, I hit the half-way mark on the fuel guage and I had 240 miles so far! This tank is on pace for at least 25 MPG.
Apparently, Kroger gas and diesel fuel is awesome stuff. I don't know who their supplier is...but wow! If you happen to be in KY or a surrounding state that has Kroger stores...stop and get some fuel.
