Looking for the best diesel fuel additives of 2022? It doesn’t matter if you drive a Ford Powerstroke, Chevy Duramax, Cummins diesel, tractor, or other diesel equipment. There are many choices of diesel fuel additives in the marketplace. This article will provide insight into many of those choices and will hopefully help you make the best decision for yourself on what to use.
Your choice of products will depend on the climate that you live in. Therefore, for our friends who live further North, a diesel fuel additive with anti-gel is preferable during the colder months. Check out our comparison of three leading diesel fuel additives to see which one performed the best for us.
Benefits of Using Diesel Fuel Additives
Diesel fuel additives play an important role in maintaining the fuel systems in our diesel vehicles. Whether you are driving trucks, boats, or tractors, it is important to keep the fuel system clean and lubricated so it runs properly.
The best diesel fuel additives clean the injectors, boost cetane, and remove water from the fuel. Therefore, they will protect the engine and prolong the life of the fuel filters. In addition, the diesel fuel additive will clean the fuel system, and remove deposits on cylinder heads. This will minimize the wear and effects on engine components. As a result, the diesel engine performance improves.
With this in mind, many people wonder if they can combine different diesel fuel additives to get the best performance? You can combine most of these products with no problems. To confirm this, you should check with the manufacturer before you combine products.
Why is Cetane Level Important?
If your car recommends 87 octane, then will it run on lower octane? Sure, but maybe not as efficiently. Would 91 or higher octane make it get better fuel mileage? Maybe, but it would surely cut down on pre-ignition and detonation.
Equally, it is the same for cetane. A higher cetane number will equal better combustion and power. They design diesel engines today to run on a minimum fuel cetane number of 40. Higher cetane will improve performance and fuel mileage to a point.
Just like with a gasoline engine, once you achieve a certain performance level for the current ECU/PCM calibration, you will not see much more in gains. If you have a tuner that constantly calibrates the injection of fuel according to the cetane and burn characteristics, then you could see gains. But, is it cost effective or prohibitive?
In most areas around the US, the minimum cetane rating at the pump for diesel fuel should be 40. Most suggest you try to obtain a cetane number in the high 40’s if possible. If you go to 50 or higher cetane, then will it justify the cost per gallon per mile? Equally, do you feel better knowing you put in a higher cetane rated fuel? Those decisions are up to you.
Our Picks For The Best Diesel Fuel Additives Of 2022!
Hot Shot’s EDT (Everyday Treatment)
One treatment of Hot Shot’s Secret EDT with each fill up will keep your diesel powering down the road. The cetane improver consists of special nitrates which speed up the oxidative process of fuels during combustion. This upgrades power and performance in all diesel equipment and increases fuel and maintenance economy. Diesel fuel will be more stable, and your engine will be in a much cleaner, more maintenance-free condition.
Hot Shot’s Secret EDT diesel fuel additive will prevent gum and sludge from forming. EDT contains a corrosion inhibitor which produces a protective, non-deposit-forming film on metal surfaces in the fuel system. This will neutralize corrosive acids that form during combustion. Water condensing in fuels can cause rust and icing in cold weather. In addition, it can cause the growth of microorganisms in the fuel during warm weather. Therefore, the operation of your diesel engine is improved when corrosion and growth of bacteria are prevented. Hot Shot’s Secret EDT contains a special demulsifier which disperses condensed moisture. It also contains an exclusive polar lubricity additive to prevent fuel pump wear without changing fuel viscosity.
EDT is recommended for ALL DIESEL ENGINES because it is completely ashless. It has no adverse effects on engine components. In addition, this diesel fuel additive complies with the federal low sulfur content requirements for use in diesel motor vehicles and non-road engines.
The level in the bottle is clearly visible, and the built-in measurement device on the top of the bottle is excellent. This is easily the best measurement device I see built into these types of products. Just open the cap, and squeeze the bottle until it fills the top to the indicator mark. It is easy to use, and guarantees consistency.
At this time, this is the diesel fuel additive that we have chosen to use. We are seeing better fuel economy so far, and Hot Shot’s Secret EDT is extremely price competitive too.

Archoil AR6500 Diesel Treatment
AR6500 will ensure correct injector spray patterns and a more complete fuel burn. This improves fuel efficiency, power and response. A more complete fuel burn also means less soot/carbon emissions produced. This keeps the engine, turbo, and emissions systems (EGR, DPF etc.) free from soot deposits.
Due to a reduction in soot emissions, vehicles equipped with a Diesel Particulate Filter (DPF) benefit from reduced frequency and length of DPF regeneration. Therefore, it results in big fuel efficiency gains. When the DPF captures less soot, much less fuel is needed to burn it off. As a result, there is less exhaust backpressure and engine efficiency loss.
Detergents keep your fuel system clean and prevent the formation of deposits that rob engine power and fuel economy. The lubricity improver prevents wear in all fuel systems including the most modern high pressure fuel systems. AR6500 also combats corrosion and disperses water to keep fuel filters clean.
Archoil AR6500 keeps fuel stable by preventing fuel from breaking down and forming sludge and varnish. Sludge and varnish do not burn easily. If left untreated, then this can plug fuel filters and injectors. Therefore, a powerful dispersant dissolves sludge and varnish and allows it to pass through your fuel system and burn completely.
Similarly, Archoil has designed their bottle for efficiency like Hot Shot’s Secret. This type of bottle design is surely the best on the market.
