What Diesel Fuel Additive Should I Use?

While the country’s diesel fuel supply is generally reliable, it is not always consistent. When constructing and certifying diesel engines, manufacturers take into account quality swings. In general, they oppose or advise against the use of fuel additives.

“We do not advise Volvo truck owners to add additives to their diesel fuel.” If additives are required, they should be added at the gasoline supplier terminal, according to John Moore, Volvo Trucks North America’s powertrain product marketing manager.

Last year, Cummins became the first company to publicly support a fuel additive, endorsing two Power Service products, Diesel Kleen + Cetane Boost and Diesel Fuel Supplement + Cetane Boost.

“Cummins engines are designed, developed, graded, and built to certify and function efficiently on commercially available diesel fuel,” according to Josh Hahn, Cummins Filtration’s coolants and chemicals business leader. “However, Cummins acknowledges that there are low-quality fuels on the market that don’t always meet ASTM D975, and that these fuel concerns can cause a range of problems for customers, including poor lubricity, low cetane numbers, low-temperature operability issues, and injector deposits.” When pour-point depressants, wax-crystal modifiers, or de-icers are required in cold weather operations, fuel additives may be required.”

“In recent years, diesel fuel quality has become increasingly critical as engines evolve and the diesel fuel manufacturing processes change,” said Roger England, director of technical quality and materials engineering for Cummins, when the Power Service alliance was announced last year.

That’s easy to comprehend when emissions regulations tighten and engine technology advances, resulting in tighter mechanical and engineering tolerances. In summary, because fuel supply uncertainty is unlikely to improve, engine manufacturers such as Cummins are taking steps to level the playing field.

Meanwhile, Detroit Diesel says it has no additional requirements beyond current ASTM specifications, but recommends that customers take steps to ensure they are utilizing high-quality gasoline.

“While Detroit does not directly advise any brand or type of fuel additive, we recommend Top Tier diesel fuel since it addresses many of the flaws in ASTM regulations addressing diesel fuel quality,” says Jason Martin, HDEP thermodynamics and fuel map management manager at DTNA. “Top Tier is a voluntary retailer program that addresses fuel stability and lubricity, as well as detergency, water, and particles – factors that help sustain the fuel system’s performance over the engine’s lifespan, which is a contributing factor to ensuring top engine performance.”

In North America, Top Tier diesel is available from a variety of vendors. “Because shops may also offer non-additized diesel fuel or diesel that does not satisfy the Top Tier regulations,” the website warns, “always verify the dispenser.”

How often should you add diesel fuel additive?

  • For best performance, add Diesel Kleen +Cetane Boost (silver bottle) if the temperature is above 30°F. To ensure peak diesel performance, this Max HP Formula is infused with cetane, detergent, and lubricity improver.
  • Add Diesel Fuel Supplement +Cetane Boost (white bottle) for winter operability if temperatures are below 30°F. This Arctic Formula will keep your fuel from gelling and your fuel filter from icing.
  • If your vehicle won’t start or get power in the cold, call Diesel 911 to reliquefy gelled fuel and de-ice frozen fuel filters.
  • To remove water, scatter impurities, and stabilize fuel for long-term storage, use Clear-Diesel Fuel & Tank Cleaner.
  • To destroy bacteria and remove remaining water and pollutants, use Bio Kleen Diesel Fuel Biocide and Clear-Diesel Fuel & Tank Cleaner.

Does diesel fuel need a stabilizer?

Diesel fuel does not last indefinitely. High-quality diesel fuel may be securely kept for up to 6 months without additives, which means that if you have a diesel truck in storage, you will ultimately need to apply these chemicals. Diesel fuel is a petrochemical made from carbon. The diesel will begin to oxidize if left for an extended amount of time, causing hydrocarbons to react with oxygen in the tank. Deposits form, which can harm fuel lines, injectors, and other system components. As a result, storing for more than 30 days necessitates the use of additives, notably fuel stabilizers. When using diesel fuel, the user must be proactive because stabilizers must be added when the fuel is new. As a result, when filling up your automobile, truck, or equipment, it’s essential to add Diesel STA-BIL. These additives are recommended not only for your diesel truck, but also for any other vehicles or equipment that isn’t utilized regularly. When storing fuel for long periods of time or for a season, keep all tanks full to avoid condensation. Because there is air in the tank and water in the air, bare interior tank walls will cause condensation.

Diesel fuel, like gasoline, is susceptible to damage if not stored properly, perhaps even more so. Because diesel engines are built differently from gasoline engines, they require a unique stabilizer.

Diesel fuel can collect moisture during storage, which encourages the growth of algae, fungi, and bacteria. The Environmental Protection Agency (EPA) mandated in 2006 that diesel fuel be lower in sulfur than prior versions. It was created as an environmentally friendly measure to produce less sulfur in the air and hence contribute to better air quality. Nonetheless, without correct fuel additives, it rendered diesel fuel less stable and more prone to cause problems. Overgrowth of bacteria, fungi, and algae jams up diesel engines’ fuel and fuel lines, leading them to run badly, if at all. Thermal oxidation, or when gasoline recirculates throughout the engine and heats up, is another difficulty with diesel engines. “Due to pressure and heat, “thermally stressed” gasoline can cause sludge and sediment to accumulate in the tank.

STA-BIL Diesel Formula removes water from fuel, preventing gumming, corrosion, and bacterial growth. It also aids in the reduction of oxidation due to thermal breakdown (from heating of the fuel).

When putting your diesel fuel engine or diesel equipment in storage, use Diesel Formula STA-BIL, 1 ounce per 5 gallons of fuel. For up to a year, this will keep the fuel fresh. If you need it to last more than a year, you can increase or even treble the dosage, which will last two to three years. If you’re going to use Diesel Formula STA-BIL on a regular basis, you can reduce the dosage to 1 ounce per 10 gallons of fuel.

It’s critical to keep fuel systems clean and clear of particles, i.e “Excellent housekeeping.” For the best historic cars and all vehicles, dry storage is also required. This keeps automobiles from being exposed to excessive levels of humidity, which can cause rust. It also helps avoid too much water in the gasoline tank, which causes condensation in the fuel tank and the rest of the car, as previously discussed. Stabilizers allow you to store diesel fuel for longer periods of time.

Can fuel additives damage your engine?

Even though most gasoline additions are safe, Trotta advises against using engine cooling system additives that claim to remedy leaks. According to her, these products will only work momentarily on little leaks, will have no effect on larger leaks, and if used excessively, could harm your car’s mechanics.

When should I add anti gel to diesel fuel?

During the winter, use your diesel fuel anti-gel every time you fill up. Before pumping the fuel, remember to add the anti-gel. This will ensure that the anti-gel is evenly distributed throughout the gasoline. This could indicate that your fuel is starting to gel.

Does Stanadyne really work?

The treatment ratios differ based on whatever Stanadyne ingredient you choose. Treatment ratios can be found on the product label or in the 99549 Diesel Fuel Additive Brochure in the Resources section of this website.

Stanadyne Fuel Additives can be stored unopened and in an appropriate storage condition for up to 24 months without deteriorating. When additives are stored for an extended period of time or in an inefficient manner, they begin to deteriorate. These additives can still be utilized, although their effectiveness may be reduced.

Why must I keep Stanadyne Fuel Additives in a temperature above freezing?

Because Stanadyne Fuel Additives will not freeze in their concentrated form once added to diesel fuel.

  • Are Stanadyne Diesel Fuel Additives compatible with high-pressure common-rail fuel systems, and would they harm aftertreatment systems?

Stanadyne Diesel Fuel Additives work with all types of fuel systems and don’t harm aftertreatment systems.

  • I’d like to become a Stanadyne Fuel Additives re-seller or distributor. What is the best way for me to learn more about this?

Up to B20, a Stanadyne addition efficiently treats the diesel (petroleum) portion of biodiesel and increases water separation, but not B100.

Stanadyne Diesel Fuel Additives are all appropriate for use in bulk storage. The rate at which it is dispersed will, however, be affected by the conditions under which it is added to the storage tank. The degree of additive homogeneity in the tank is determined by a number of parameters, including the temperature of the base fuel and additive, the size of the bulk storage tank, and the degree of agitation in the tank. If the storage tank is mixed or agitated, the additive will be homogeneous and stay that way. However, because the rate of dispersion is dependent on the conditions described above, the level of dispersion in the storage tank will be an unknown variable if there is no mixing/agitation. Add the recommended ratio of fuel additive to the tank before adding the fuel to achieve optimal dispersion in a bulk storage tank. Mixing and agitation will be provided by the addition of the base fuel. The mixture in the fuel tank should be homogenous at the end of the fueling process.

The antioxidants in Performance Formula will help to keep stored diesel fuel stable for up to a year.

A Performance Formula Injector Cleaner contains concentrated detergents to clean CR Injectors and the fuel system as needed, as a “One Tank” clean up, or when performance concerns emerge. Use 4–6 times per year for preventative maintenance or at every oil change interval.

The Gasoline Additive+ cleans the fuel injection system with concentrated detergents, ethanol protection, and a corrosion preventative. It should be used on a regular basis, especially when performance concerns occur and as preventative maintenance. Once a month is recommended. Because of the ethanol protection and fuel stabilizer benefits, fuel should be treated with Gasoline Additive+ if the car and/or small engine will be stored for an extended period of time.

Demulsifiers let microscopic water droplets emerge from suspension/emulsion, allowing the filter/separator to extract water more effectively. Detergents added to diesel fuel additives have a tendency to emulsify water into the fuel, which can cause a variety of problems. This is why all Stanadyne Fuel Additives contain demulsifiers. Emulsified water in gasoline can result in a number of problems, including:

  • A decrease in combustion speed results in still burning particles striking the cylinder wall and crown.
  • Fuel delivery difficulties are caused by the volatility of the fuel in the pumps before it enters the engine.
  • Is it true that Stanadyne Diesel Fuel Additives are designed to prevent asphaltenes from clogging filters?

All Stanadyne Fuel Additives, with the exception of Winter 1000, contain detergents that help disperse asphaltene molecules and reduce fuel filter clogging.

Q: Does injector cleaner work on diesel engines?

Yes, injector cleaner can be used on diesel engines if the system is appropriate. Make certain it says you may use the formula with diesel. If you use biodiesel, make sure it addresses ethanol concerns. Many cleansers may be used on all sorts of engines, but choosing the wrong one can result in issues.

Q: How often should you use diesel injector cleaner?

If your car is getting up there in mileage, aim to use a fuel injector every 1,500 miles. You can stretch it to 3,000 miles if you have a newer vehicle. Fuel injector build-up is unavoidable, so don’t push it any further. The sooner you deal with it, the better.

Q: Can you use too much diesel injector cleaner?

While most gasoline injector cleaners claim that adding too much won’t hurt you, proceed with caution. The required concentration is stated on all of the containers. Look at the amount of fuel it’s supposed to treat and follow the directions. This manner, the detergent build-up won’t create damage, negating all the job the cleaner could have done otherwise.

Q: How long does it take for an injector cleaner to work?

It’s a frequent misunderstanding that the outcomes are instantaneous. The cleaner removes water within a few minutes of driving, however it takes longer to remove the deposits. The cleaner will take full action after a week of regular driving. Keep track of when you use it and how it affects your gas mileage at the start and after a week. The treatment was successful if you detect a difference.

Q: What are the signs of a clogged fuel injector?

An engine that won’t start or is difficult to start, a lower MPG (indicating lower fuel economy), increased hydrocarbon emissions, and non-firing cylinders are just a few of the warning indicators. Also, if you open the hood of your vehicle and see traces of diesel on the spark plugs, you have a clogged fuel injector.

Q: How does a diesel injector cleaner work?

Most cleaner fluids work by mixing with diesel in the fuel tank, then sending it down the fuel rail, injectors, and into the combustion chambers via the fuel pump. The cleaner breaks down solid particles into soluble bits and cleans any traces of rust in the tank throughout the operation. The remaining cleaner liquid is blown out the exhaust system of the car.

Q: How often should I clean my diesel injector?

Before you start having problems with the engine or injectors, you should first clean your fuel injector. Deep cleaning of the diesel injector should be done at least once a year or every 30,000 kilometers. However, the age of your car, your driving circumstances, and the type of fuel you use all have a role. The suggested clean-up interval for your fuel injector may be found in your vehicle’s owner’s manual.

Q: Should I use fuel additives to boost the cleaner?

After using the injector cleaning, fuel injector additives can be utilized to improve the performance of the fuel injector. The additives are placed into the fuel tank to extend the life of the gasoline, prevent build-up or corrosion, and lubricate the injectors. As a result, you should clean the deposits with a gasoline cleaner and then apply fuel additives to assist keep the fuel system cleaner for longer.

Does Cummins recommended fuel additive?

Cummins Inc. has chosen to formally approve and suggest two Power Service Products diesel fuel additives – Diesel Kleen +Cetane Boost and Diesel Fuel Supplement +Cetane Boost – after internal studies revealed that both help boost engine performance.

“As engines evolve and diesel fuel manufacturing processes change, diesel fuel quality has become increasingly critical,” said Roger England, director of technical quality and materials engineering at Cummins, in a statement.

He went on to say that the Diesel Kleen and Diesel Fuel Supplement additives aid with difficulties such as poor fuel lubricity, low cetane numbers, low temperature operability issues, injector deposits, and so on.

England also mentioned that using Kleen +Cetane Boost all year helped clean filthy injectors, reduce injector sticking, smooth rough-running engines, and improve fuel economy.

According to Ed Kramer, president of Power Service Products, his company’s Diesel Fuel Supplement +Cetane Boost is a winterizing/anti-gel used to prevent diesel fuel gelling and to keep fuel-filters from plugging with ice and wax during the winter months when temperatures drop below 30 degrees Fahrenheit.

“Paraffin (wax) in ultra-low-sulfur diesel fuel (ULSD) will gel as temperatures drop, preventing fuel from flowing through the engine, and water in the fuel will freeze on the facings of fuel-filters, preventing fuel flow,” he stated. “This mix ensures trouble-free diesel fuel operation in the winter.”
