The heart of the diesel engine is its fuel injection equipment and the major enemy of this equipment is poor quality diesel fuel. From our extensive research and testing and our experience in manufacturing diesel fuel injection systems, Stanadyne found that variations in diesel fuel quality around the world can adversely affect today’s precision fuel injection systems. Poor quality diesel fuel can cause performance issues, premature wear, gumming of components, and plugged filters. To resolve these issues and to provide protection of the fuel injection system, Stanadyne developed its own line of diesel fuel additives.
Stanadyne diesel fuel additives are the only ones in the world that are:
- Made by a fuel injection systems manufacturer
- Tested and approved by major diesel engine and vehicle manufacturers
- Proven to perform best in independent tests
Stanadyne diesel fuel additives protect and improve the performance of all diesel fuel injection systems including:
- High pressure common rail
- Unit injectors
- Rotary distribution pumps
- In-line pumps
Stanadyne diesel fuel additives comply with federal low sulfur content requirements for use in diesel motor vehicles and nonroad engines.
Performance Formula
The premium all-season, multi-function diesel fuel additive, designed to tackle virtually any diesel fuel related problem.
- Restores/Increase Horsepower – detergents clean deposits in the injection system resulting in improved combustion, better acceleration, power, and torque
- Reduces Fuel Consumption – independent tests show an average of 4% improvement in MPG and gains up to 9.6%
- Cetane Improver – improves combustion resulting in better engine starting, smooth running, and reduced engine noise
- Meets all engine fuel system requirements and will not harm exhaust aftertreatment systems
- Reduces Emissions – reduces Smoke and Particulates
- 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 – keeps fuel fresher and protects against formations of gums caused by oxidation
- Cold Weather Protection – improves 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
- Corrosion Preventative– Corrosion inhibiters will protect the fuel system from rust and corrosion
- Helps Remove Water – special demulsifiers cause tiny water droplets to come out of suspension/emulsion, so the filter/separator can more effectively remove water
- Contains No Alcohol – avoids corrosion and accelerated wear
- Specially Formulated for use with ultra low sulfur diesel fuel
- Can be used with Bio Diesel Fuel up to B20 (20% bio content approved ) – increased water separation shown in bio content up to B20

Performance Formula Injector Cleaner
Stanadyne Performance Formula Injector Cleaner is formulated to prevent and eliminate Internal Diesel Injector Deposits (IDID) commonly found in Common Rail and other type of Injectors. These deposits affect injector performance, which results in various engine related issues.
Performance Formula Injector Cleaner is a “One Tank” Clean-Up of concentrated detergents designed to eliminate & prevent internal and external deposits from forming on injectors. The result is restored Engine Performance, Increased Horsepower, and Improved Fuel Economy.
Other benefits and recommendations:
- Lubricates fuel system components to help prevent wear
- Cetane improver improves combustion resulting in better starting, smoother running, and reduced engine noise
- Use 4 – 6 times per year as preventive maintenance or when engine performance issues arise
- Continued use of Performance Formula All Season or Performance Formula Warm Weather recommended with every fill-up
