Hello, only 18 cases of DEF were delivered to my home today. I recall ordering 20 cases, so why are two cases missing?

That this works well with my truck and is at a great price
Used this Super Tech DEF 2.5 Gallon in my 2022 Freightliner Cascadia for over 125,000 miles with zero performance issues. It meets all OEM requirements. My only concern is the foil seal under the cap; small particles can occasionally drop into the tank opening when pouring. Just be careful when opening to prevent potential contamination. Overall, it's a reliable, cost-effective alternative to name brands. Highly recommended for the performance.
Item was shipped on its side. It is a liquid and spilled out.
Product is great! But they delivered a leaky bottle of DEF and it got all over my travertine at front door. Hopefully it will not stain. This product is every bit as good as the name brands.
We ordered def and the driver left them very far near mail boxes, and we had to bring them by ourselves. Not a good service. Next time please deliver in front of my apartment door.
Great DEF. Don't buy into marketing hype including the industry shelf life nonsense. roflmao…I bought 2 pallets back in 2020 and just ran out. Kept them in climate controlled garage/out of the sun and no problems after 5-years using it in a very expensive Cummins engine. Other brands seem to be an absolute rip-off—gouging consumers $10/gal when diesel itself is currently $4/gal! Thank you Walmart for the value/savings and quality product and of course to the delivery driver dropping them off (free) at the garage threshold.
I use this DEF regularly for my diesel truck, and it works exactly as it should. It's compatible with diesel engines that use SCR systems and helps reduce emissions while keeping everything running smoothly. The quality is consistent, and I haven't had any issues using it. It pours easily and does what it's designed to do without any complications. We keep this on a subscribe-and-save order because the price is great and it's convenient to always have it on hand. Overall, a reliable product at a great value — definitely recommend for any diesel vehicle that requires DEF.
Ordered 4 boxes, one box was leaking. The delivery was not great, left message for delivery that we are a business open 8-4 m-f, they attempted delivery twice at 6:30 pm. On the third attempt at 6:30 pm they left the product by the door which was fine.
