Old World 1 gal Diesel Exhaust Fuel

The Blue DEF product seems to have a loyal following among customers who have been using it for many years without any issues. One customer even mentioned that they received a new tank for their vehicle when they encountered a contamination indicator, which indicates that the company stands behind their product. The spout and vent of the product have been improved, making it easier for customers to use without the need for additional measures like taping or wrapping. This suggests that the company is continuously working to enhance the user experience. Customers appreciate the convenience of ordering from Sam's and the confidence they have in using this product. It is praised for being the right size for trucks and less expensive than buying from a truck stop. Delivery service is also commended for being prompt and reliable. However, there is some disappointment expressed by a customer who used to purchase the product in-store but now can only find it online with a minimum purchase requirement of 2. This raises concerns about the cost-effectiveness for Sam's Club. Overall, the Blue DEF product seems to have a positive reception among customers, with its ease of use, quality, and reliability being the key selling points. The improvement in the spout and vent is appreciated, although some customers may find the online-only availability and minimum purchase requirement inconvenient.
