Each 16 oz bottle treats 60 gallons of ultra low sulfur diesel or B20 biodiesel, improving horsepower, fuel economy by up to 9.6%, and reducing emissions and engine wear. Trusted by mechanics and diesel enthusiasts alike, it’s the all-in-one additive for year-round engine protection and optimized performance. ## Description Stanadyne Performance Formula Pint Bottle 16oz., Case of 12 Bottles Treats 60 gallons diesel fuel per Bottle 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. Review: Everything you need in one bottle - I drive a 2016 Ram 3500 with the Aisin transmission so I have the highest of the 3 power ratings the Cummins come with for that model year. I've always run an additive in it since the day I bought it. I was using another brand that is sometimes considered number one depending on the review you're reading. In a lot of the reviews I came across this additive was also at the top so I decided to do some more research. One of the first things I liked is that it's developed by a company that makes fuel system components for diesels. The second is that it's actually endorsed by some of the vehicle manufacturers. Third is that everything you need (cleaning, lubrication, cetane booster, winterizer/anti-gel and so on) is in one bottle. I called Stanadyne because you can get bottles for one specific purpose such as lubricity or winterizer and I was curious if those are more effective at doing that specific job than the blue bottle that contains them all in one. They do not, it's just as effective in the blue bottle as it is in the individual bottles however, the treatment ratio is different. I was still hesitant to purchase this stuff since I couldn't buy it in the big jugs like I could the other stuff. I decided to check on here and to my surprise I came across this case right here. This is an excellent value and the product is great. I'm a mechanic and very maintenance cautious, I strongly believe in preventative maintenance and just taking care of your vehicle in general. With diesel being what it is these days and the costs of fuel system components, anything I can do to preserve or extend the life of the components, I'm all for it. Since my truck isn't very old and I've used another additive prior to converting to this, I didn't have performance issues. One thing I was very happy to notice is the fuel mileage, according to the data screen on my truck. I've never seen better 17.7 to 18.0 MPG average on the highway. I drove to the beach and back the other day and was averaging 19.2 last time I looked at it before I made it home. While that may not be a significant increase, I was certainly pleased. I will continue using this stuff from now on and I will buy all my cases from right here as I've looked and not found a better deal for a case yet. Review: Verified Protection. Not A Tank Through My Truck Without This Product - If you have a Diesel engine, truck, car or something else, you need a fuel additive. Have used for years in the tractor. Never a fuel issue. I was using the Ford Performance Enhancer & Cetane Boost in my truck, but during the freeze of 2021, it did not prevent icing--really not its fault as it does not have anti gel capabilities. They make one that does, but it does not boost cetane. This does it all; is economical (8 oz to a full tank) and seems to keep things going. Stanadyne, a maker of fuel injection parts, was not happy with the available additives and, so, developed their own. It may be like taking vitamins--if you don't get ill was it because of the supplement--but, it is cheap enough and the fuel is of such low quality that it seems to be good insurance. Some improvement in fuel economy and performance, also a plus. ## Features - Restores/Increase Horsepower: detergents clean deposits in the injection system - Reduces Fuel Consumption tests show an average of 4 percent improvement in MPG and gains up to 9.6 Percent - Cetane Improver improves combustion resulting in better engine starting, running and reduced noise - Reduces Wear: Lubricity improvers restore lubricity to ultra low sulfur diesel fuels - Reduces Emissions reduces Smoke and Particulates ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000M46TEU | | Best Sellers Rank | #20,227 in Automotive ( See Top 100 in Automotive ) #33 in Diesel Additives | | Brand | Stanadyne | | Bulb Type | Southwest Diesel - Authorized Distributor | | Customer Reviews | 4.8 4.8 out of 5 stars (844) | | Date First Available | December 20, 2006 | | Is Discontinued By Manufacturer | No | | Item Weight | 0.01 ounces | | Item model number | add38565 | | Manufacturer | Stanadyne | | Manufacturer Part Number | 38565C | | Mirror Adjustment | Helps Remove Water – special demulsifiers cause tiny water droplets to come out of suspension/emulsion, so the filter/separator can more effectively remove water | | OEM Part Number | 38565C | | Product Dimensions | 11 x 9 x 10 inches | | Special Features | Specially Formulated for use with ultra low sulfur diesel fuel Can be used with Bio Diesel Fuel up to B20 (20% bio content approved ) | ## Images ![Performance Formula Diesel Fuel Additive - 16 Oz.

Buying this on subscription is the cheapest way to get it. Most local autoparts stores want absurd money retail for them anymore. I've tried a lot of different additives over the years, I would argue that Stanadyne's is one of the best at cleaning and keeping clean injectors and restoring performance. I've lost count of how many clapped out, neglected old diesels I've bought over the years and have never failed to be impressed by how much performance just this fuel additive alone can restore after a few tanks with an ounce or two of this additive per tank. Not sure if I've gotten huge mileage bumps from it, but certainly for restoring and keeping the original performance of your fuel system, this is the stuff to get. ## Frequently Bought Together - Stanadyne Performance Formula Diesel Fuel Additive - 16 Oz.
