Description
Product Overview
NuDEF Diesel DEF Additive is engineered to maintain the integrity of diesel exhaust fluid (DEF) in demanding operating conditions. Formulated with high‑purity urea, the additive lowers the freezing point of DEF, preventing crystal formation that can clog tanks, pumps, and injectors. Packaged in a compact 2 × 2 × 6.5 inch container weighing 10.2 oz, it treats up to 25 gallons of DEF, making it suitable for both fleet maintenance and individual truck owners. The product complies with ISO 22241 standards, ensuring compatibility with all SCR systems.
Usage
Designed for diesel engines equipped with selective catalytic reduction (SCR) technology, this additive is ideal for use in cold climates, long‑haul routes, and stop‑and‑go urban driving where temperature fluctuations are common. Simply add the recommended dose to fresh DEF before filling the tank, or top up existing DEF to restore its performance. Regular use helps maintain optimal emission control, reduces downtime, and extends service intervals for the DEF tank, pump, and injector assemblies.
