1. Level of Urea in DEF
Although there are numerous brands of best DEF fluid for Cummins available in the market, you should tend to choose the one that is approved. You must go with the brand that makes the use of pharmaceutical-grade urea instead of agriculture-grade urea. Agriculture-grade urea is characterized by impurities like biuret that is present in higher levels in such urea.
2. Level of impurities
You must choose to go with only those brands of DEF that have a limited percentage of impurities that may include zinc, iron and aluminum. Only such kinds of DEFs cater to the requirements of the EPA standards. When poor-quality deionized water is used, the above-mentioned impurities enter the DEF easily. The presence of too many impurities in the DEF may result in the premature failure of the SCR system. In such cases, you should choose to go with DEF that are not too cheap, have fewer impurities and meet the EPA standards.
3. Recommendations of manufacturers
If you are facing perplexities while choosing a particular brand of DEF for your vehicle, you can always go with the recommendations of the manufacturers.
