Understanding DEF Fluids: A Buyer’s Guide
Choosing the appropriate exhaust fluid for your Cummins engine is a significant task. Understanding Diesel Exhaust Fluid (DEF) and its importance is the first step. This non-hazardous solution significantly contributes to reducing harmful emissions from your engine.
The quality of DEF is of utmost importance. Choosing a diesel exhaust fluid that meets ISO specifications is essential for optimal engine performance. Keep in mind, that substandard DEF can result in contamination, triggering vehicle safeguards.
Another essential factor is proper storage. DEF should be stored within a temperature range of 12°F and 86°F to preserve its quality and prevent it from becoming frozen def. Avoid direct sunlight and store it at temperatures below 75°F for a shelf life of up to two years.
You should avoid running out of DEF at all costs, as it can lead to the need for most def fill-ups and even damage your def tank. Running out of DEF triggers a response from your vehicle’s control system, reducing speed to prompt refilling and prevent operation without DEF.
Summary
Choosing the right exhaust fluid for your Cummins engine is crucial for optimal performance and emissions control. Remember, the best exhaust fluid balances cost, longevity, purity, and reliability. With the right exhaust fluid in your def tank, you can ensure your engine runs smoothly while keeping emissions in check.
