When I first ordered this DEF, description said that the minimum order for the product were 2 x 2.5 gals. But the price was so reasonable that I went ahead and ordered it. My 2019 Ford F250 diesel's DEF was at half tank. I used one of the 2.5 gal container to fill the tank. I still have another container left. Love it.
An essential product for diesel engines and costly at the dealership. Reasonably priced at your neighborhood Walmart. Comes with a filling nozzle and is easy to fill without spilling a drop! The only problem may be the weight of the 2.5 gallon container if you are on the puny side.
I have used Blue DEF for years, and it works really well. Perhaps one drawback is that it has a poor venting system for pouring, but I just punch a couple holes in the top away from the spout with an awl.

What is this? Is it an additive for oil or fuel??

1. No, this is a special fluid that is only for diesel engines that require diesel exhaust fluid (DEF). The DEF is used for a process whereby the diesel particulates (dark diesel exhaust) is collected in a special unit; and then periodically burnt up using DEF. For engines requiring DEF, there is a special port marked for DEF refilling only. These diesel vehicles normally have a special gauge which tells whether there is enough DEF. These vehicles also give warning messages when the DEF is low.
5. Someone previously advised that the engine "mixes" this to clean the exhaust. This is not correct. Diesel exhaust fluid is sprayed by a ninth injector (V8 engines) into the SCR (Selective Catalytic Reduction) system. It's a means of converting nitrogen oxides, also referred to as NOx with the aid of a catalyst into diatomic nitrogen, N2, and water, H2O. A gaseous reducing agent, typically anhydrous ammonia, aqueous ammonia or urea, is added to a stream of flue or exhaust gas and is absorbed onto a catalyst. Carbon dioxide, CO2 is a reaction product when urea is used as the reducing agent. Selective catalytic reduction of NOx using ammonia as the reducing agent was patented in the United States by the Englehard Corporation in 1957. Development of SCR technology continued in Japan and the US in the early 1960s with research focusing on less expensive and more durable catalyst agents. The first large scale SCR was installed by the IHI Corporation in 1978.
