Bardahl DEF-Shot Diesel Additive - DEF Cleaner & Anti-Crystallization Treatment, 32oz

Diesel owners with modern emissions systems, this Bardahl DEF-Shot is like insurance for your expensive SCR system.

DEF crystallization is a real problem that can clog injectors, lines, and the entire exhaust treatment system, leading to reduced power, poor fuel economy, and costly repairs.

This 32-ounce bottle treats 16 gallons of DEF, eliminating existing deposits and preventing new crystallization from forming.

It helps restore proper DEF spray patterns, which reduces consumption and keeps your emissions system working efficiently.

The result is better engine power, improved fuel economy, and prevention of those annoying engine derate situations where your truck loses power.

Usage is simple - just add it to your DEF jug before filling the tank (never add to fuel tank).

For the price of one treatment, you're potentially avoiding thousands in SCR system repairs or component replacements.

It's particularly valuable if you operate in extreme temperatures or don't drive frequently enough to keep DEF circulating regularly.

The formula is designed to protect the entire DEF system - tank, pump, heater, lines, injector, and mixer.

Whether you're a fleet manager maintaining multiple vehicles or an individual owner protecting your investment, this additive provides affordable prevention against some of the most common and expensive issues with modern diesel emissions systems.
