Diesel Exhaust Fluid Blue Def for Diesel vehicles and SCR System (1) 2.5 Gal USA


Top 5 reasons why getting an oil change is so important:

1. Oil is the key ingredient to a properly performing engine; it reduces friction, provides lubrication, lessens wear and tear, and keeps engine parts cool. New oil acts as a cleansing tool to your engine and helps clean dirt and buildup from old motor oil that could potentially damage the engine.

2. Oil protects your engine and provides a layer of protection between the moving parts of the engine helping to keep all parts from wearing down. Oil also protects your engine from corrosion caused by condensation.

3. Low oil levels can mean there are a number of potential issues such as, but not limiting to leaking oil in other areas of the car, or burning oil in your car?s engine. Or even just a simple leak of oil out of the engine due to a seal leak or washer wearing down.

4. Regular oil changes help improve fuel efficiency or your miles per gallon (MPG) and help to reduce fuel consumption in general. Your engine uses fuel more efficiently when it is running well which means overall better gas mileage for your automobile and extra money in your pocket. The investment you make in regular oil changes will translate into fuel savings over the life of your vehicle.

5. Be environment friendly! When your engine is running well on clean oil, it produces less exhaust emissions. Older vehicles may even burn oil that is degrading, adding even more emissions to the exhaust, making regular oil changes even more of a priority.

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.

  • Mixture of 32.5 percent high purity synthetic urea and 67.5 percent deionized water
  • Used in selective catalytic reduction systems on diesel engines to assist in converting NOx to harmless nitrogen and water
