Def Fluid LIfe
Hi all, My 2013 Duramax has been sitting in my garage since last Oct. Should I be worried about the DEF fluid degrading and possibly causing problems when I hit the road this month? Couldn't find ...

Pilot/Flying J's have it in bulk at semi fuel pumps. Here in Syracuse, I think it was around $3/gallon at Pilot. Can fill the pick up here, but not the VW. Have to fill jug up at pump, pour into another bottle and then into VW's tank. Bit of a pain, but far cheaper than VW dealer.
The last DEF I bought at WM was 8-9.00 for 2.5 gallons. Considering the LOW consumption rate our TVs have, the money saved by buying at a bulk station isn't much.
Our DEF systems are designed to quit if there is something wrong with the DEF. This will result in the TV going into limp mode at a minimum. Then a trip to the dealer, and possibly some very expensive repairs.. There is no drain in the DEF tanks. It has to be removed to dispose of bad DEF.
There are many things that can do wrong in a bulk purchase.
I prefer to use the sealed jugs that have production/dste codes.
IMO, the risk reward ratio is just not favorable enough for buying in bulk.
Meh, do you buy the sealed cans of premix gas by the qt for $8.99 for your weed whipper, or do you dump some 2s oil in a gas can and hit the local Kum n Go for a gallon of "bulk" gas?
Same concept. LOTS of big rigs burnin up tons of def and refilling every day.
Yes buying sealed, fresh def is pretty much a sure thing, but stopping at the def pump at a flying J is too!
I'm the guy that buys the freshest milk in the fridge, but if I get a gallon that's 2 days older I still drink it!
