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.
What things specifically can go wrong? Semis get DEF at fuel pumps. We have bulk DEF at work for our semis. Handle clicks off when full just like a fuel handle does. All the truck stops turn over DEF at a good clip and I'm willing to bet they don't want any complaints w/ their set up, so they keep things in good shape. Is bulk DEF for everyone? No. It's more of a convience thing if possible. But I'd like to know what problems exist w/ getting DEF at truck stops.
