00203 1-Gallon Diesel Exhaust Fluid

It now comes in a different container as the one they advertise. It no longer has a bleeder valve on it. Container is round just like windshield washer fluid comes in. I bought this because the container had the relief valve on it but now they don't come that way. Plus I waited over a month for this product. Needless to say I will not buy this product again. It was advertised on Jan. 27, 2016 as "Terra Cair 00203 1-Gallon Diesel Exhaust Fluid - 4 Pack" As others have said I expected 4 gallons of this.

Product is good but shipping cost is more than product.

Great price. Has a unique filler tube with built in air valve, was able to put a gallon into the DEF tank in well under 10 seconds with no mess.

This was listed a 1-Gallon 4 pack when I ordered it. I waited over a month to receive it and when I did I received only 1 gallon.It appears that since my order was placed in January the description no longer states 4 pack.
