Description

Stanadyne Performance Formula protects your diesel engine and restores engine performance. The detergent and cetane improver in Performance Formula will help restore fuel economy, increase horsepower and torque. Stanadyne Performance Formula 1/2 gallon (64 ounce) jug treats 240 gallons diesel fuel. Note: All Stanadyne Diesel Fuel Additives can be blended with each other and "double-dosing" is not damaging - although it may not provide twice the benefit. Where engine and vehicle OEMs have approved Stanadyne, most of them recommend Performance Formula, which should be used year-round to ensure protection against fuel related problems.

    • Awesome product.
Been using Stanadyne product in my '97 Dodge 3500 for 23 years, 232,000 miles. Never had any fuel or injector problems. Use it year round. But only use a small quantity (25%) of winter recommendation. It is a great cleaner/lubricant in the summer. I think it also helps fuel mileage. 20-22 in town and 25-26 on the road. Definitely recommend. ... show more

    • High quality fuel treatment
I have used this product about 10 years now, and it has proven to be a fantastic treatment for my 20 year old diesel engine. I use it year round as lubricant, and it has protected the fuel to -10F.

    • Cetane booster!
Improves fuel efficiency. American diesel is poorer quality compared to other countries.

    • Great additive for diesel engines
I noticed a significant difference in the smoothness of my diesel engine idle and performance when using this additive. Buying in this bulk sizing is also a great way to save money. My only complaint - I have to carry a graduated cup / beaker to measure correct dosage amounts. It would be nice if the container had an ounces marking on the container. ... show more

    • Needed to clean my skid loader injectors. This was recommended by my mechanic.
One tank with this stuff and I have noticed much smoother operation. I recommend Stanadyne as a fuel system additive and will continue to use it in mine!

    • The jury is still out.
Hard to tell if the performance improved as of yet. It dies appear as though the staring performance has improved.
