I pull a 5th wheel every other month, does def fluid burn faster when towing heavy loads? About 13k lbs
Yes it uses more def when towing, but not a huge difference. Have also heard others say if the def is weaker due to heat or age it will use more also. Some of us that donít put many miles on need the Chemists to come up with DEF stabilizer like what Stabil does for gasoline. Maybe it already exists, anybody?
