2. DEF Diesel Exhaust Fluid - 5 gallon pail

DEF diesel exhaust fluid, is the mixture of high purity synthetic urea and deionized water that is used in Selective Catalytic Reduction (SCR) systems on diesel engines. Blue def is injected into the exhaust stream via a controlled dosing module where the water vaporizes leaving ammonia molecules free to travel in to the catalytic converter where it reacts and neutralized the NOx molecules, converting it to nitrogen and water.

Ready-to-use formula Made from high purity urea and deionized water Contains no chemical additives or other compounds that could cause SCR system failure Meets the quality standards established by the ISO-22241-1 for Diesel Exhaust Fluid Certified by the American Petroleum Institute

Sub Brand: Blue DEF;Brand Name: Peak;Product Type: Exhaust Fluid;Compatible Fuels: Diesel;Container Size: 1 gal.;Packaging Type: Bottle; Diesel exhaust fluid (DEF) is one of the key elements of the selective catalytic reduction process used by diesel engine builders to meet EPA 2010 regulations. BlueDEF is a nontoxic solution of 67.5 percent purified water and 32.5 percent ultra pure automotive grade urea. BlueDEF is not a fuel or fuel additive. Instead, when injected into the exhaust stream and passed over a catalyst, BlueDEF helps convert NOx into nitrogen gas and water vapor-two harmless and natural components of the air we breathe.

7. Lucas Diesel Deep Clean, Pint | 10872

Lucas Diesel Deep Clean, Pint | 10872 Lucas Diesel Deep Clean is a new Lucas technology developed to reduce the cost and hassle of particulate filter maintenance. It is an excellent preventative maintenance product. It causes the fuel to burn much cleaner, thus eliminating a lot of particulate matter that would otherwise go into the exhaust system causing “regens.” It also cleans out much of the matter already trapped in the filter. This eliminates exhaust backpressure allowing the engine to run easier and cooler as well as lowering the aggravation and down time associated with particulate filters. Key Benefits: Reduces particulate matter in filters Cleans fuel s Restores power loss Improves acceleration
