Common DEF System Problems And How To Fix Them
Common DEF system problems cause engine de-rate or limp mode. Typical issues include crystallized fluid clogging injectors, contamination from dirt or wrong fluids, freezing at low temperatures, and sensor failures. These problems, often triggered by low or poor-quality DEF, can cause faulty readings and costly SCR system damage. DEF is a key component in the…

The Key Differences Between Diesel Fuel: Diesel 1 vs Diesel 2 Fuel
Diesel #1, or winter diesel, is lighter and resists gelling in freezing temperatures, making it ideal for cold climates. Diesel #2 is denser, offers better fuel efficiency and lubrication, and performs best in warm weather or heavy-duty engines. Diesel fuels come in two main types—Diesel 1 and Diesel 2. While both power diesel engines, they…

DEF in Cold Weather: Temperature of DEF Freezing Point
Diesel Exhaust Fluid (DEF) freezes at 12°F (-11°C) due to its 32.5% urea and 67.5% deionized water composition. Freezing doesn’t reduce DEF quality, but expansion during freezing can damage containers. Most vehicles use DEF tank heaters to thaw the fluid automatically. Diesel Exhaust Fluid is a mixture of deionized water and urea. This solution is…

What Happens to Diesel Fuel in Cold Weather?
In cold weather, diesel fuel thickens and gels, potentially clogging fuel filters and causing engine issues, as the paraffin wax it contains solidifies into crystals. These issues can result in reduced fuel flow, engine damage, and in extremely low temperatures, the cloud point can be triggered, where wax crystals form, causing fuel cloudiness. What Happens…

How to Winterize a Generator
To winterize a generator, prepare it for storage by stabilizing the fuel, changing the oil, cleaning the air filter, and optionally disconnecting the battery to prevent drain, and consider using cold flow improvers, engine block heaters, battery warmers, snow hood kits, and louvers/dampers. Running the generator for 10-15 minutes before use warms the fuel and…

How To Prevent Diesel Fuel Gelling?
Prevent diesel fuel gelling by: Using winterized diesel or anti-gel additives Keeping fuel tanks full to reduce condensation Storing vehicles and equipment in warmer environments Using engine block heaters or fuel heaters Replacing fuel filters before winter Monitoring and removing water contamination What Is Diesel Fuel Gelling? Diesel fuel gelling is the process where wax…
