Glad she was able to get the DEF filled. I topped mine off yesterday. Purchased two 2.5 gallon jugs from Sam's for $10.94 each. It took about 4 gallons to fill the tank with 3,800 miles on the clock. Neat little plastic nozzle included. Didn't spill a drop. I can't find a pump at any truck stop within 40 miles from my home. We have truck stops everywhere and each one has 50 video poker machines but no DEF pump. They have the 2.5 gallon jugs for $14.99 each.

 

Try the national chains, they usually have them at the pumps. I don't remember where you are, but there's a Love's in Vinton, Iowa, Duson, Shreveport, and Port Allen, T/A in Lafayette, Shreveport, Pilot in Breaux Bridge, Hammond, Rayville, Flying J in Shreveport, Petro in Hammond.

 

Whoa, did the dealer fill it to the brim when you bought it? Good she hit a truck stop; however I see auto parts stores carry it too, although it is cheaper at truck stops.

 

Yes the dealer filled it right before i left the lot. It has never been back to the dealer though. So no computer update or anything done. Im wondering if that may play a part.

 

Thanks for your service!

 

As long as the DEF doesn't hit zero we're good. I have had mine down to 50 miles left before filling. I did this on purpose to replace the DEF left from the summer. DEF has a very short shelf life in hot weather (above 90 F). As soon as warm temps come again (and not soon enough), I fill the DEF tank to no more than half. This way it won't go bad.

 

Q. What is the shelf life of DEF?
A. The shelf life of DEF is directly related to the ambient storage temperature. DEF will degrade over time depending on temperature and exposure to sun light. If stored between 10 and 90 deg F, shelf life will easily be one year. However, if the maximum temperature does not exceed approximately 75 deg F for an extended period of time, the shelf life will be two years.

 

I'm letting mine run down just to see what happens. Truck stop 5 miles away has it at the pump. My buddy just bought a Duramax and I was reading up on his system. It gives a warning at 1000 miles and another at 300. When empty it limits you to 55mph and the longer you drive it will keep reducing that speed down to 35mph. the truck will continue to run on empty but once shut off it will not restart.
Anyone know the what the Eco does?

 

Regarding def nozzles at the pump:

The one I used was a perfect fit for our trucks. It seems as though the nozzles at various locations/pumps are inconsistent. This was at the "real" truck lane.

 

I am just East of Morgan City. I appreciate the truck stop locations you listed. I am in Hammond, Breaux Bridge, and Lafayette pretty often. I will include these in the notes on my Iphone. Thanks again Ziggy and be safe.

 

Interdasting. I'll be delivering in the Gibson area tomorrow morning. Bayou Black to be exact...
