Description

Diesel exhaust fluid is one of the key elements of the Selective Catalytic Reduction (SCR) process used by most medium and heavy-duty engine builders to meet EPA 2010 regulations. is a non-toxic solution of 67.5 percent purified water and 32.5 percent ultra pure automotive grade urea. Blue DEF is not a fuel or fuel additive. Instead, when injected into the exhaust stream and passed over a catalyst, helps convert NOx into nitrogen gas and water vapour, two harmless and natural components of the air. is stable, colourless and odourless, and meets ISO Standards 22241 for purity and composition and is an American Petroleum Institute (API) certified diesel exhaust fluid. These are the highest quality and safety standards in place to ensure optimum SCR performance. Making sure you do not run out of in a SCR equipped truck is simple, watch the Diesel Exhaust Fluid (DEF) gauge, which is part of the diesel fuel gauge, for when it is time to refill. DEF is stored in a dedicated tank next to the fuel tank on the driver's side. The tanks range in size from 6 to 23 gallons depending on the truck's application. The DEF tank fill opening is designed to accommodate a DEF fill nozzle to ensure only DEF is put into the tank. A diesel fuel nozzle will not fit into the DEF tank opening.

  • Awesome price for the amount of products you get.
You get a great price for 4 or more packages of these compared to buying one. The shipping was a bit confusing because they came separately and in two different days. I almost contacted the seller & Amazon customer service because I thought that half of the product did not get delivered. But, waited until COB the next before making a claim. The next day, an unmarked car delivered the other half of the products I ordered. Some of the container leaked a little DEF fluids when taking them out of a long box. So, BE CAREFUL with kids and wear gloves when unpacking. Other than that, products are as described. ... show more

  • Great price, works perfectly.
This is the good stuff. My prior motorhome with a Cummins ISL9 didn't like the cheaper DEF but ran fine on this. My F-350 doesn't seem to care.
