I'm working on a complete library of date codes. Blue def ultimate guide + date code blue def does have a limited shelf life If the valvoline def bottles are anything like their oil cans, then you are going to have difficulty determining the manufacturing date and the shelf life of their def product. When def is in good shape, it should look clear and free of any contaminants or discoloration If it is cloudy, discolored, or difficult to see through, it is likely expired. This code has to be broken down to get the exact date of manufacturing so you can tell if the blue def is going to expire shortly
Ga = the plant that made the blue def 2 15 = the year of manufacturing + 1 year So the batch was made in 2014 3 359 = number of days. Def shelf life is determined by how long the solution effectively neutralizes harmful diesel fuel emissions Typically, def expiration dates are set at one year from the date of manufacture
Def is simply water and urea, with a 32.5% urea concentration. Make sure you are using fresh def in your diesel pickup truck. This date code will tell the exact date the batch was produced and subsequently the age of the bottle of def One gallon containers have a laser code imprinted on the bottle. A date code, or date of manufacture, can be found on just about any package of def This is called out in the specification for def
How to read the date of manufacture on bluedef also known as peak brand (commonly found in walmart and other retail locations). Just curious as to whether anyone knows how to interpret the new code for blue def I’m assuming this box is relatively new since it has the new code, but it’d be nice to know when it was manufactured.
