Stanadyne Performance Formula Diesel Fuel Additive – 16 oz, Case of 12

Stanadyne Performance Formula is a diesel fuel additive designed to optimize combustion and protect critical fuel system components. Packaged as a 16 oz bottle, this formula is also available in a convenient case of 12, making it practical for fleets or households seeking consistent maintenance throughout the year.

What sets this additive apart is that it blends with other Stanadyne products and is compatible with existing aftermarket blends. Each bottle covers about 60 gallons of diesel fuel, so a full case covers a substantial portion of a maintenance cycle. The approach is practical and user-friendly, aiming to support smoother operation without requiring dramatic changes to your routine.

Key benefits you may notice

• Restores and increases horsepower by cleaning deposits in the injection system, helping the engine respond more readily to throttle input.
• May improve fuel efficiency; tests show an average MPG bump around 4%, with some cases reporting as high as 9.6%.
• Cetane improver enhances combustion, contributing to easier starting, steadier idle, and quieter operation under load.
• Lubricity enhancers restore protective film in ultra low sulfur diesel fuels, supporting wear resistance in injection systems.
• Emissions management: formulations can help reduce smoke and particulates when the engine is running under typical conditions.

How and when to use

Stanadyne Performance Formula is designed for year-round use and is compatible with other Stanadyne diesel additives. OEMs that approve Stanadyne often recommend Performance Formula as part of regular maintenance to help prevent fuel related problems.

• One bottle treats up to 60 gallons of diesel fuel; a case of 12 bottles covers up to about 720 gallons.
• The product can be blended with other Stanadyne additives; double dosing is safe but may not double the benefit in every situation.
