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…

How Does Cold Weather Affect the Fuel Economy?
Cold weather decreases fuel efficiency by 10-20% due to factors like denser air increasing drag, thicker oil creating friction, and longer engine warm-up times. Additionally, colder temperatures cause tire pressure to drop and can decrease the electric-only range of hybrid and electric vehicles, thereby increasing reliance on the internal combustion engine. Cold weather can have…

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 Clean Diesel Fuel Filters Fast and Safely
To clean a diesel fuel filter, relieve system pressure, remove the filter, drain old fuel, and clean the element using compressed air or brake cleaner. Rinse it with clean diesel, reinstall it, and bleed air from the system to restore proper fuel flow. When we neglect the cleanliness of the diesel fuel filter, the engine won’t…

Why Clear Diesel is More Expensive Than Dyed Diesel Fuel
Clear diesel costs more than dyed diesel because it includes federal and state highway taxes used to fund public roads and bridges. Dyed diesel, marked red for off-road use, is tax-exempt and intended for equipment like tractors or construction machinery, making it significantly cheaper per gallon. Why Clear Diesel is More Expensive Than Dyed Diesel…

Can You Mix Dyed and Clear Diesel?
Mixing dyed (off-road) and clear (on-road) diesel is technically possible but not recommended. Doing so poses legal risks, potential engine damage due to higher sulfur content in dyed diesel, and negative environmental impacts. Using dyed diesel in vehicles meant for public roads can lead to fines or criminal charges and may harm modern emission systems…

How Long Does Diesel Last in a Generator?
When stored properly in a generator tank, diesel fuel typically lasts 6 to 12 months, but with maintenance and ideal storage, its lifespan can extend up to 18 months. Factors affecting its shelf life include exposure to oxygen, temperature, water contamination, general contamination, and microbial growth. Fuel polishing can remove contaminants and water, extending fuel…
