We sell only Stanadyne Performance Formula, the only additive proven best in independent lab and real world vehicle testing manufactured by a Fuel Injection Equipment company.
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
Rotary distribution pumps
Stanadyne diesel fuel additives comply with federal low sulfur content requirements for use in diesel motor vehicles and nonroad engines.
