Schaeffer's Diesel Treat 2000 Ultra Low Sulfur Year-Round Blend

Schaeffer's Diesel Treat 2000 Ultra Low Sulfur Year-Round Blend is an ashless, all-season diesel fuel additive formulated for use with all types of diesel fuel, especially low sulfur and ultra-low sulfur diesel fuels. If diesel fuel does not contain an effective detergent (and most don't contain any), varnish and carbon deposits can clog injectors robbing you of as much as 25 percent of your power and performance. Diesel Treat 2000 contains a highly concentrated, multi-functional additive system to improve fuel economy, injector cleanliness and fuel stability and to optimize performance. Diesel Treat 2000 contains a non-alcohol jet fuel deicer/water dispersant to remove moisture present in the fuel and prevent the formation of stable-fuel-water emulsions. Further blended into Diesel Treat 2000 is Schaeffer's proprietary lubricity additive, SynShield, which prevents fuel system wear and injector scoring for longer component life. Protect your investment with Schaeffer's products. Product features and performance benefits: * Diesel Treat 2000 meets cleanup and keeps clean performance as shown by the Peugeot DW10 Injector Depositing Test throughout the entire fuel system * Diesel Treat 2000 is registered and meets US EPA requirements for blending into low sulfur diesel fuels—contains less than 15PPM sulfur * Disperses insoluble gums and varnish present in low quality fuels * Excellent deposit control for light duty and medium duty in-direct injected diesel engines * Improves fuel's cetane rating up to 4 points * Anti-wear protection throughout fuel system * Eliminates black filter deposits * Reduces emissions, exhaust smoke and particulates * Helps restore and optimizes horsepower * Protects fuel system against rust and corrosion * Improves fuels economy
