Stanadyne Performance Formula® Diesel Fuel Additive

•The premium all-season, multi-function diesel fuel additive, designed to tackle virtually any diesel fuel related problem
• Meets all fuel system requirements
• Approved by Original Equipment Manufacturers (OEMs)

• Cold Weather Protection - reduces diesel pour point up to 40°F (22°C), and cold filter plug point by up to 25°F (13°C), depending on base fuel
• Hot Weather Protection - lubricants and cetane improver help when fuel is hot and “thin”
• Increases Horsepower - with up to 5 point cetane gain to improve combustion, resulting in better acceleration, power and torque
• Reduces Fuel Consumption - independent tests show gains up to 9.6% in MPG
• Easier and Faster Starting - in all conditions
• Reduces Smoke and Particulate Emissions - and is suitable for ultra low sulfur diesel
• Cleans and Protects - detergents and deposit modifiers help protect injection pumps, injectors, nozzles, etc.
• Reduces Wear - lubricity improvers restore lubricity to ultra low sulfur and other low lubricity diesel fuels
• Stabilizes Fuel - antioxidants keep fuel fresher
• Contains No Alcohol - avoids corrosion and accelerated wear
• Helps Remove Water - special demulsifiers cause tiny water droplets to come out of suspension/emulsion, so the filter/separator can more effectively remove water
• Specially Formulated for use with ultra low sulfur diesel fuel
• Can be used with Bio Diesel Fuel (up to B5, or 5% bio content)

Diesel Fuel Update from Stanadyne Corporation

Diesel fuels are changing and as a diesel engine owner or operator you want to know how you might be affected by these changes. You may have heard of Ultra Low Sulfer Diesel. ULSD (also reffered to as S15) is now available in North America and mandated for on-highway use throughout the U.S. by the end of 2006. You may also have heard of bio-diesel. This fact sheet will inform you of the advantages and disadvantages of these fuels and how Stanadyne's additives can assist.

Ultra Low Sulfur Diesel

Beginning in 2006 diesel fuel for on-highway use must have no more than 15 parts per million sulfur. This is a 97% reduction from the previous limit of 500 ppm. Sulfur is removed from diesel fuel at the refinery by a process called hydro-treating, which also effects the fuel in other ways. The American Society for Testing and Materials (ASTM) publishes the standard for mineral diesel fuel - ASTM D975 which refineries comply with.

Advantages of Ultra Low Sulfur Diesel

• Reduced exhaust emissions
• Improved cold startability and reduced white smoke at cold startup

• Higher cost
• Lower energy content. Less BTU's per gallon means reduced power and fuel economy
• Possible premature fuel system wear. The process of removing sulfur can also reduce the natural lubricity of the fuel. There is now a lubricity specification in the D975 standard but it is not as high as what the fuel system manufacturers recommend.
• Compromised fuel stability. ULSD tends to be less stable and will deteriorate sooner than previous diesel spec.
• Fuel System leaks. Reducing sulfur also reduces aromatics. This can result in rubber seals and hoses in some fuel systems to shrink and result in fuel leaks.

• Reduced exhaust emissions
• Made from renewable resources
• Almost no sulfur (in bio-diesel itself)
• Higher cetane value (51 min vs 40 min for mineral diesel)
• Excellent lubricity

• Could harm certain elastomers (seals)
• Has poor resistance to oxidation especailly when blended with ULSD. This results in spoilage and the formation of acids and varnishes
• Bio-diesel can absorb much more water than mineral diesel
• Has lower energy content

• Lubricates fuel system components to help prevent wear caused by low lubricity fuels
• Increases cetane value which in turn helps starting, reduces smoke, increases power and fuel economy
• Provides cold weather protection by reducing the fuel pour point by up to 40 dergees F (22 degrees C)
• Helps de-mulsify water so that the water separator can work more efficiently. Standyne additives do not contain alcohol which can emulsify water into the fuel where it then comes out of suspension when the engine cools down and corrodes expensive fuel injection components
• Has a stabilizer to keep fuel fresher longer

• that are made by a diesel fuel injection equipment manufacturer
• are approved by major diesel engine manufacturers including GM, Ford, VW, John Deere, Navistar, Caterpillar and AM General
• have been proven to perform the best in independant tests
