Schaeffer Diesel Treat 2000™ Ultra Low Sulfur Winter Premium is a multifunctional diesel fuel additive engineered to prevent fuel gelling, waxing, and fuel line freeze-up in cold weather. It also boosts cetane rating, improves fuel economy by up to 3%, protects injectors and fuel pumps from wear, and disperses water to prevent fuel-line freeze-up. It works in all diesel fuels, including low sulfur diesel and biodiesel blends.
As temperatures drop, diesel engines face a unique set of challenges. Paraffin wax naturally present in diesel fuel begins to crystallize in cold conditions, clogging fuel filters and starving engines of the fuel they need to run. Add in the risk of water contamination freezing inside fuel lines, and winter becomes a season that can bring entire fleets to a standstill.
Diesel Treat 2000™ Ultra Low Sulfur Winter Premium was formulated to address exactly this problem, while also delivering year-round performance benefits that keep engines running cleaner and more efficiently.
What does Diesel Treat 2000™ do for cold-weather diesel performance?
Diesel Treat 2000™ Ultra Low Sulfur Winter Premium is a multifunctional, ultra-low-sulfur-compliant additive designed to provide maximum cold temperature protection against fuel gelling, waxing, and fuel line freeze-up. Beyond winter protection, it improves fuel efficiency, increases power, boosts fuel lubricity, enhances injector cleanliness, and extends fuel stability.
The product has proven clean-up and keep-clean performance, as demonstrated in the Peugeot DW-10 Injector Depositing Test. This means it doesn't just prevent new deposits from forming inside the fuel system—it actively works to remove existing ones.
Diesel Treat 2000™ is compatible with all types of diesel fuel, including low sulfur diesel and biodiesel blends, making it a versatile choice for mixed fleets.
How does Diesel Treat 2000™ improve engine performance?
Schaeffer Diesel Treat 2000™ contains a highly concentrated, multi-functional additive package that delivers measurable performance improvements when used at the recommended treatment ratio:
· Higher cetane number: Improves the fuel's cetane number by 2 to 4 points, supporting easier cold weather starting and reduced misfiring at lower air inlet temperatures.
· Faster warm-up: Helps engines reach optimal operating temperature more quickly in cold conditions.
· Proven deposit control: Clean-up and keep-clean performance verified through the Peugeot DW-10 Injector Depositing Test, the Cummins L-10 Injector Depositing Test, and the Cummins N-14 Injector Corrosion Test.
· Better fuel economy: Improves combustion by fully vaporizing fuel into smaller particles, delivering fuel economy gains of up to 3% while preventing power loss.
· Reduced emissions: Lowers exhaust smoke, particulates, and black smoke output.
· Anti-wear protection: Provides excellent wear protection for injectors and fuel pumps, plus supplemental ring and valve-train protection.
· Fuel system lubrication: Lubricates upper cylinders, fuel pumps, and injectors.
· Improved stability: Increases fuel thermal stability to resist degradation and inhibits oxidation during storage, extending shelf life.
· Rust and corrosion protection: Shields the entire fuel system from rust and corrosion.
For fleets operating in low-quality fuel environments, Diesel Treat 2000™ also disperses insoluble gums and varnish, providing deposit control for both light-duty and medium-duty direct-injection diesel engines.
How does Diesel Treat 2000™ handle water in fuel?
Water contamination is one of the most common causes of winter fuel system failure. Even small amounts of entrained or dissolved water can freeze inside fuel lines, filters, and injectors, leading to blockages and breakdowns.
Diesel Treat 2000™ addresses this with a non-alcohol jet fuel deicer and water dispersant. Instead of allowing water to pool or form ice crystals, this component breaks it into tiny droplets and suspends them within the fuel. These droplets travel safely through fuel filters and lines in controlled amounts, ultimately reaching the combustion chamber where they're burned off along with the fuel.
This dispersal process also prevents the formation of stable fuel-water emulsions, which can otherwise cause long-term damage to fuel system components.
Who should use Diesel Treat 2000™?
Choose Diesel Treat 2000™ if your fleet operates in regions with cold winters, uses low sulfur diesel or biodiesel blends, or has experienced injector fouling, fuel gelling, or water contamination in the past. It's especially valuable for light-duty and medium-duty direct-injection diesel engines, where deposit buildup can quickly erode performance and fuel economy.
Prepare your fleet before the cold sets in
Cold weather fuel problems are far easier to prevent than to fix. Treating diesel fuel with Diesel Treat 2000™ Ultra Low Sulfur Winter Premium before temperatures drop helps keep fuel systems clean, engines running smoothly, and vehicles on the road all winter long. Talk to your fuel supplier about adding Diesel Treat 2000™ to your winter fuel program before the first freeze arrives.
Frequently Asked Questions
What does Diesel Treat 2000™ protect against in cold weather?
Diesel Treat 2000™ protects against fuel gelling, wax crystallization, and fuel line freeze-up, all common causes of cold-weather diesel engine failure.
Can Diesel Treat 2000™ be used with biodiesel blends?
Yes. Diesel Treat 2000™ is compatible with all diesel fuel types, including low sulfur diesel and biodiesel blends.
Will Diesel Treat 2000™ improve fuel economy?
Yes. By improving combustion through better fuel vaporization, Diesel Treat 2000™ can improve fuel economy by up to 3%.
Does Diesel Treat 2000™ clean existing injector deposits?
Yes. Its clean-up and keep-clean performance has been proven in the Peugeot DW-10 Injector Depositing Test, and it also modifies existing injector deposits so they can be safely burned off in the combustion chamber.
How does Diesel Treat 2000™ handle water contamination?
It contains a non-alcohol jet fuel deicer and water dispersant that breaks water into tiny droplets, preventing fuel-water emulsions and allowing water to pass safely through the fuel system to be burned with the fuel.
