I order this stuff online because I don’t like interacting with weird people. I don’t know if it’s cheaper in stores or not, I don’t really care. To not have to talk to someone at the gas station or auto parts store is worth it to me. Of all the synthesized cow piss on the market for trucks that require DEF, this seems to be the creme de la creme, squoze from only the finest pure bred Holstein heifers and mixed with mountain spring water. I have used this brand for 5 years and while I have no idea if it actually does anything other than make my truck’s exhaust smell horrible, it hasn’t ever created any mechanical issues with the truck. I ordered the two pack and received two, 2.5 gallon jugs, as advertised. The spout that is included sure makes refilling the tank easy, and then I throw that away with the jug that the DEF comes in, which is inside of a cardboard box, inside the Amazon box. Somehow DEF makes the environment better, I don’t get it. But I’m apparently not as smart as the folks at the EPA. I mean, who figured out that a mixture of water and urine extract, injected into an exhaust and then processed through and SCT and/or DPF would save the Earth from some unburnt fuel? Remarkable foresight. Yay for government!
