DEF message

[TinStarArabs]

I just got home from a long trip in my 2015 Winnebago ERA. The DEF warning came on during the last leg of the trip. I have been told that I can add at a truck stop or buy from the automotive store. It seems like it would be hard to add at a truck stop because it is under the hood and not by the diesel fuel tank. I have to pull my book out and read but was wondering if any here had experience with this. I have just under 5000 miles and am not due for an oil change until 15,000.

If the chassis and engine of your 2015 ERA is like our 2015 View the DEF tank (which we access under the hood) only holds about 3 gallons. I have been told that is enough for 3-4,000 miles. We have bought DEF in 2 1/2 gallon containers at Walmart.

Just buy 2.5 gallon DEF at Walmart or Tractor Supply and add it to your DEF tank. It is likely located on the left front under the hood. If any spills, just rinse thoroughly with water.
