9 best diesel fuel conditioners
Diesel fuel conditioners are additives that are used in diesel engines to improve fuel quality, enhance engine performance, and maintain the health of the fuel system. These additives are designed to address specific issues related to diesel fuel and the operating conditions of diesel engines. Here's what you need to know about diesel fuel conditioners:
Fuel Quality Enhancement: Diesel fuel conditioners are formulated to improve the overall quality of diesel fuel. They can help remove impurities, water, and contaminants that can negatively impact engine performance and fuel system components.
Cetane Number Improvement: Cetane is a measure of the ignition quality of diesel fuel. Diesel fuel conditioners often contain cetane boosters that increase the cetane number of the fuel, which can result in easier cold starts, smoother combustion, and reduced engine noise.
Fuel System Cleaning: Many diesel fuel conditioners contain detergents and cleaning agents that help remove carbon deposits and varnish buildup from fuel injectors, pumps, and other fuel system components. This can lead to improved fuel atomization and better combustion efficiency.
Water Dispersal: Water can be a common issue in diesel fuel, especially in storage tanks or due to condensation. Diesel fuel conditioners often contain water-dispersing agents that help prevent the formation of water droplets and protect the fuel system from corrosion and microbial contamination.
Lubrication: Some diesel fuel conditioners include lubricity additives that can help compensate for the reduced lubricating properties of ultra-low sulfur diesel (ULSD) fuel. These additives can protect fuel system components from premature wear.
Cold Weather Performance: In colder climates, diesel fuel conditioners with anti-gel properties can prevent the fuel from gelling or waxing in low temperatures. This ensures that the fuel remains flowable and prevents clogs in the fuel system.
Emissions Reduction: Certain diesel fuel conditioners are formulated to reduce harmful emissions from diesel engines, such as nitrogen oxides (NOx) and particulate matter. They may be used to meet emissions regulations or improve the environmental impact of diesel engines.
Fuel Stabilization: Diesel fuel conditioners can help stabilize diesel fuel during long-term storage, preventing degradation and the formation of sludge or sediment.
Injector and Pump Protection: By keeping the fuel system clean and lubricated, diesel fuel conditioners can extend the lifespan of fuel injectors, pumps, and other critical components, potentially reducing maintenance costs.
It's essential to follow the manufacturer's instructions and recommendations when using diesel fuel conditioners. Different additives may serve different purposes, so selecting the right one for your specific needs is important.Additionally, always use products that are compatible with your diesel engine and fuel type to avoid potential issues.

User questions & answers
Question: | I currently run archoil fuel additive. i want to switch to this product. do i need to empty my current tank of diesel and refuel before adding this |
Answer: | use your current fuel as normal down to 3/4 or less and then add your power service and fuel |
Question: | Does this product reduce regen cycles in cummins engines |
Answer: | No, it is a cetane boost and injector cleaner only. It us recommended by Cummins and will not affect your warranty but has no effect on the DEF syztem whatsoever. |
Question: | shelf life |
Answer: | As long as you keep it in sealed tight container (aka close the lid tight after you used) you'll be fine for a very very very long time. |
Question: | I have a 2002 cummins, do not have to use def fluid. I use 5 oz. per 10 gallons in a 35 gal. tank. Is this about the correct mix |
Answer: | From previously reading up about this I believe the correct amount should be 9 oz 435 gallons of diesel. When I have mixed it at half that ratio I just don't get the performance I do if I put 9 oz. Don't take me as a gospel but that's what I'm using. |

User questions & answers
Question: | I use a 5 gallon fuel can to fill my tractor. I read that 1oz treats 10 gallons. What is recommended to treat 5 gallons? 1/2oz |
Answer: | Yes, that is correct. For in-season, use 1oz for 10 gallons. For storage, use 1oz for 5 gallons. If you have a 5 gallon tank. Use 1/2oz for in-season use and 1oz for storage. Do not over treat. |
Question: | once opened, what is shelf life of stabil, diesel stabilizer |
Answer: | Bottle states that it will be good for 2 years after opening. They even have a spot where you can fill in the open date to be sure. Just note that it stabilizes for 2 years from opening. So, opening it, letting it sit for 23 months, then adding it to fuel, will only stabilize the fuel for an additional month. |
Question: | Does this do anything for the Algae |
Answer: | This is just a fuel stabilizer. There are other additives you can get that take care of algae, but this isn't one of those. |
Question: | Can i use this in my no.2 home heating oil every now and then, to prevent settlements and water? help |
Answer: | No. 2 heating oil is very similar to diesel fuel so yes, you can but thorough mixing is critical. You can't just pour thus product into your already filled tank. Ideally, you would want to mix this product in as your heating oil is being pumped into the tank. This will increase the shelf life of your heating oil, but it won't stop sediment that is already in the oil from a rusty or dirty tank. Also be sure you mix in the recommended right ratio of product to heating oil. |

User questions & answers
Question: | I saw a study showing the usage rate to be 13 ozs per 26 gallons of fuel, has this changed? I see now the concentration calls for 8 ozs |
Answer: | Add 4 ounces to a 100 gallon tank. |
Question: | Is it biodiesel compatible and to what %? the diesel place comparison doesn't show it as compatible like stanadyne and other additives |
Answer: | This product is made for coarse and curly hair to help it form waves during daily brushing sessions. It will not create curls in straight hair. You can still get waves if you have some curl to your hair, but you will have to grow your hair longer and you will end up with a few wide waves instead of several skinny waves. |
Question: | How many oz per tank full |
Answer: | It helps but by itself it wouldn’t do much. Brushing and wearing a wave cap are really the only ways to get waves |
Question: | Can you run this in summer as well. I ask because it performes better than the summer Opti - lube formula when it comes to lubricity |
Answer: | Gives them a softer more relaxed look with a mild shine. I have tight curls so it loosens into a soft wave. I use wave scarf at night to hold for days! |

Product description
BG DOC Diesel Oil Conditioner is designed to condition oil in high-output diesel engines. Diesel engines operate at high temperatures and pressures. This puts a lot of demand on diesel engine oils and the additives they contain. Hydraulically activated fuel injectors increase oil pressures and emissions devices increase soot accumulation in oil. These systems test the limits of engine oil. Under the right conditions, heat causes sulfur from fuel to combine with entrained moisture to create sulfuric acid. This acid wreaks havoc on engines, causing corrosive wear and severe damage to engine components. BG DOC Diesel Oil Conditioner maintains like-new diesel engine power and performance, neutralizes acids and acid corrosion, reduces friction and wear on engine parts, stabilizes viscosity, and prevents sludge through increased oxidation control and soot scatter technology. BG DOC is compatible with all diesel engine oils including synthetic and multi-grade. BG 245 Premium Diesel Fuel System Cleaner removes and dissolves deposits from the entire diesel injection system, including fuel injectors and combustion chambers. Diesel fuel is notorious for its instability. Without adequate fuel stability to control deposit formation, diesels are extremely sensitive to fuel breakdown. This can increase deposit buildup, leading to heavy exhaust emissions and power loss. In newer high pressure common rail (HPCR) direct injection engines, high temperatures and pressures can cause diesel fuel to breakdown into carbon deposits more quickly. The result is poor performance and potential engine damage. Current diesel fuel system cleaners remove deposits from the injector tip but fail to reach inside the injector itself. BG 245 removes and dissolves deposits from the entire diesel injection system, including inside fuel injectors and combustion chambers. BG 245 is especially effective in removing heavy deposits inside the injectors of high temperature, HPCR fuel delivery systems.
