Re: 2011 Dmax fuel economy
New update on the 2011 duramaxes that we are using for work: #2(purchased about a month ago) has a shade under 2k miles on it. #1 is, believe it or not, sniffing 10k! I didnt realize we'd gone that far in it already. Today when I showed up for work neither of them were there. The one 06(spare), the 07(hooked up to a tandem axle,16' enclosed trailer), and one of the guys personal 07 dodge 6.7 were enlisted for todays job. The 2011's were both froze up. We were blaming the fuel but they were all fueled up the same place the day before. We arent sure if the urea catalyst froze or the diesel gelled. My guess is numero uno. Frozen catalyst. Its freezing point is 17*. Bosch said the fords have an insulated tank that they draw the urea into upon shutdown or if the fluid reaches a certain temp to avoid freezing. They couldnt give any info about the gm.
Anybody feel free to chime in! Four dmax's were filled up with at least 20gal of diesel from the same station, same pump and two identical ones gelled the older ones did not.
I did blame and verbally place blame on the guys running the trucks even though none of the four trucks were given additives. I told them a month ago, several times, to quit running bio and buy the 100% petrol from the sister station in town. Laziness prevailed and the trucks wouldnt run.
Anybody seen anything similar? I know the older trucks we had did wax/clog filters but again you cant rely on the service station to provide fuel that wont wax. Even though they should. Kerosene works well for that....
