(2 pack) Super Tech Diesel Exhaust Fluid (DEF), 2.5 gal

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.

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.

Have been using this DEF for just over 4 years now and without any problems, as I see it why pay more for the blue stuff being that all DEF has to meet the same EPA standards for purity. The one thing you need to be sure of no matter what brand you buy is to look at the date code to be sure its not more than 3-4 months from date of manufacture as DEF is normally only good for 12 month from date of manufacture, you also do not want to buy DEF that has been sitting in the sun as heat and sun shorten DEF shelf life.

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.

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.

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

product did not come.with the funnel

Item was shipped on its side. It is a liquid and spilled out.

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.
