Because diesel exhaust fluid is required by law for vehicles equipped with SCR that were produced after January 1, 2010, the best choice is one that improves performance and helps ensure cleaner emissions. DEF, when used in an appropriate SCR system, improves engine lubricant and filter life. It’s a safe, eco-friendly and formaldehyde-free formula that’s specifically made to meet AUS 32, DIN 70070 and ISO 22241 purity and concentration standards.
With a urea concentration of 32.5 percent, +/- 0.7 percent, this innovative blend features fewer than 0.5 ppm of heavy metals such as iron and aluminum; it has fewer than 0.2 ppm of copper, zinc and chromium.
