I use this all the time for my Mercedes Benz E350 Diesel. I love the price. Better than in most stores.

My son had been buying his DEF at a truck stop. I did a search and found that WalMart carried the same product at a far lower price.

Works fine with Cayenne diesel. I purchased the DEF when it was $8.50 in 5/16 but now the price has gone up recently.

We always use Blue Def on our Dodge Ram 3/4 ton work truck with no problems. This is a good product.

Very easy to use. Flexible hose is long enough to be placed into the filler tube on the car while keeping the box upright.

[This review was collected as part of a promotion.] Good product. We've gotten this item from multiple suppliers, Walmart was cheapest.

Unbelievable price. I’ve been buying it there for 4 years. I saved four dollars to seven dollars a box by going to Sam’s Club.

This is the most respected of the widely available DEF brands. Walmart had it at the lowest price in my area.

The Blu DEF is the only brand I use in my diesel pusher and you can't get it cheaper and easier than at Walmart AND home delivery.
