Buying Guide for Best Diesel Exhaust Fluid
These are some of the important features to look for when buying the best Def fluid for Duramax
- Shelf Life: Diesel exhaust fluid (DEF) has a limited shelf life, typically around 1-2 years, so it’s important to choose a fresh product that has not been sitting on a shelf for too long. Look for DEF with an expiration date as soon as possible to ensure the product will be effective for its shelf life.
- Boat-Ability: Boat-ability refers to the ability of the DEF to remain effective and function appropriately in a marine environment. If you plan to use DEF in a marine diesel engine, choosing a product specifically designed and tested for use in this application is important.
- Pour-Ability: Pour-ability refers to how easily the DEF can be poured and dispensed into a vehicle’s DEF tank. Look for DEF with a nozzle or spout that is easy to use and prevents spills or splashing. Some DEF products also come with a vented nozzle to help prevent glugging.
- Corrosion Protection: Diesel exhaust fluid can be corrosive to some materials, so choosing a product that is compatible with the materials used in your vehicle’s DEF system is important. Look for DEF tested and approved for use with your vehicle’s specific DEF system.
- Cleanliness: DEF should be pure and free of contaminants to ensure the proper functioning of the vehicle’s emissions system. Look for DEF manufactured and packaged using dedicated equipment to ensure the product is pure and contaminant-free.
- Toxicity: DEF is non-toxic and safe to handle, but choosing a product formulated to be environmentally friendly and non-hazardous in case of accidental spills or leaks is essential.
- Electrolytic Stability: Electrolytic stability refers to the ability of the DEF to resist breakdown and maintain its purity over time. Look for DEF formulated to maintain its purity and stability throughout its shelf life.
- Temperature Range: DEF can freeze at low temperatures and may become less effective at high temperatures. Hence, choosing a product tested and approved for use in your specific temperature range is important. Look for DEF rated for the temperature range you will be operating in.
- Heap-Ability: Heap-ability refers to the ability of the DEF to resist settling and maintain a consistent mixture over time. Look for DEF formulated and packaged to maintain consistency and prevent settling or separation throughout its shelf life.
- Filler Neck Compatibility refers to the Diesel Exhaust Fluid (DEF) nozzle fitting into the vehicle’s DEF tank filler neck.
