About this item:
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.

5.0 out of 5 stars 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.
5.0 out of 5 stars How do you know? Start-Stop rough when turning off before.
Always curious how people give reviews on preventative products. I have had my Audi A7 TDI for 50k miles before I started using this at 110k and it always had a rough stop. After using 4oz per fill for 8-10 (5k miles) tanks I have noticed it now shuts down smoother. I am fairly certain this product is why. Personally I purchase the 64oz bottle and then put 8oz in a small juice bottle and keep it under the hood for two tanks making it much more cost effective. I plan to keep using this product.
5.0 out of 5 stars 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.

Stanadyne does not provide the results of HFRR results for this additive. Contacted them HFRR data - they answered that they outsourced additives to a different company (Parker Hannifin) and I should contact them. In my opinion if you name is on the bottle you should now stuff about it, or redirect the request accordingly, not to football people. According to Spicer Report on lubricity improvement additives this additive makes a tiny improvement: -33µm for values 350-400µm. Under 10%.Did not see data for cetane improvement.Bought lubricity formula from Opti Lube, will probably switch to them for Performance formula too. But not a bad product per se.
5.0 out of 5 stars 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!
