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.”
Is additives good for diesel engine?
Diesel fuel additives can provide a variety of benefits. Incorporating a gasoline additive into your tank can aid with lubricity, cold-weather performance, and even make your fuel more stable. Additives can improve and protect, as well as smooth and correctly fuel, all at a low cost. We have the items and information you need if you think your car could benefit from an additive. Check out which products we consider to be the best diesel fuel additives on the market.
Do I need to add anything to my diesel fuel in the winter?
Diesel fuel has a lot of advantages. More vehicle power means better fuel economy, but one of the main disadvantages of diesel fuel is that it performs poorly in cold weather. Diesel crystallizes when temperatures drop, clogging fuel filters and lines. This not only prevents engines from starting, but it can also result in costly repairs if the engines are damaged.
You should apply an anti-gel fuel supplement to keep diesel gasoline from gelling (or crystallizing). Anti-gel additives are simple to apply; simply add the remedy to your gasoline tank. Anti-gel additives lower diesel fuel’s freezing point, making it less prone to freeze in cold weather. Anti-gel additives are used to reduce the plugging point of cold filters (CFPP). The CFPP is the lowest temperature at which a filter will still allow fuel to flow through it.
The presence of wax in diesel fuel necessitates the addition of an anti-gel additive. Normally, wax is a liquid that dissolves in the fuel. The wax is the problem because it causes fuel to gel, and gelled fuel (or crystals) can clog engine fuel filters. If the temperature drops below a certain point, the engine will totally gel up and cease to function. So why don’t we just remove the wax and avoid the whole gelling issue? The wax component is there because it contributes to the fuel’s high cetane value. Cetane provides more power and improved engine response. In the winter, wax concentration is lower, but it is still present in diesel blends for cetane.
1. When the temperature drops below 32 degrees Fahrenheit.
It’s a good idea to start using anti-gel as soon as the temperature drops below freezing. As a general rule, the lower the temperature, the more gasoline additive is required. We recommend that you follow the anti-instructions gel’s on the bottle.
2. Sudden temperature dips
If the weather forecast predicts a cold front, you should prepare by applying additional anti-gel ingredient. The importance of preparation cannot be overstated. Anti-gel additives will not harm your engine, so use extra when in doubt.
3. When it comes to adding fuel
Whenever you fill up at the pump in the winter, use an anti-gel additive. Most additives can be put either before or after the fuel is added. To guarantee a good mixing, we like to add the ingredients ahead of time.
4. When the fuel starts to solidify
As soon as feasible, add an anti-gel ingredient. If your fuel has already gelled or your fuel lines are clogged, an emergency additive that dethaws fuel and de-ices filters is recommended. These emergency procedures re-liquify the fuel, making it combustible once more.
We provide a few anti-gel additives at Fuel OxTM as a precautionary step. We recommend that you use our Gasoline OxTM Cold Charge to prevent fuel gelling. We recommend utilizing our emergency fuel treatment, Fuel OxTM Heat Bomb, to restore the flow of frozen fuel lines if the fuel has already gelled. A little goes a long way with this product, as it does with all of ours; one ounce treats up to 80 gallons of fuel. A complete list of our winter anti-gel additives can be seen below:
How often should you use 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.
Are fuel additives necessary?
It’s worth noting that fuel additives keep crud out of your gas tank, fuel line, and (most significantly) your fuel injectors. Carbon deposits can build up in your vehicle’s fuel injectors over time, causing them to bog or clog.
Which diesel fuel additive is best?
The best additive in the game is Diesel Extreme. This one raises the cetane rating of diesel by seven points (improving the fuel’s combustion performance once again), as well as cleaning and lubricating injectors and other essential fuel system components. Diesel Extreme also aids in the removal of impurities and excess water from fuel.
How cold is too cold for diesel?
When it comes to diesel trucks, how cold is too cold? At 15 degrees Fahrenheit (-9.5 degrees Celsius), the diesel fuel in your fuel tank will gel and you will have problems starting your engine. Your diesel vehicle will have troubles if the temperature drops below 15 degrees Fahrenheit / -9.5 degrees Celsius. The diesel won’t be frozen solid, but it won’t be liquid either. You must now rely on heating solutions such as block heaters and glow plugs, which are not available on all diesel engines.
There’s a lot of debate regarding what temperature is too cold for a diesel truck. On the internet, it is stated that the freezing point of diesel fuel is roughly -112 degrees Fahrenheit or -80 degrees Celsius. Now you believe you will never be in a region that gets that cold, so you should be fine. Wrong.
It is not necessary for the diesel in your fuel tank and fuel lines to be solidly frozen to cause you problems. When the temperature drops below 15 degrees Fahrenheit / 9.5 degrees Celsius, the diesel fuel begins to change shape and becomes more like a gel. Consider a gel-like fuel that travels from the fuel tank to the engine. Traveling through the fuel lines would be difficult, and you would have difficulty starting your engine in the frigid winter.
How cold does it have to be for diesel to gel up?
- Gelling: It’s unusual to have a situation where the fuel practically turns to jelly. Gelling happens when the paraffin wax in diesel solidifies due to a drop in temperature, and the fuel’s temperature must be kept below minus 10 degrees F for extended periods of time, such as 48 to 72 hours. When diesel is cold soaked, the paraffin wax in the fuel hardens, giving it a hazy look. At temperatures as high as 32 degrees F, the fuel will begin to cloud, but it will continue to flow. Before the fuel can gel, it must be kept at a very low temperature for an extended period of time. It’s common to hear drivers complain about their fuel gelling up, but this is almost certainly not the issue they’re having. Ice or solidified paraffin wax in the fuel filter is more likely to be the issue. There’s more on that later.
- Cloud Point: To determine the cloud point of a sample of diesel fuel, which is the temperature at which the naturally present paraffin wax in #2 diesel fuel begins to crystalize, there are prescribed methods. The fuel has a hazy look due to the microscopic particles of suspended hardened wax. Cloud point temperatures for diesel fuel typically vary from -18°F to +20°F, but can reach +40°F depending on a variety of factors connected to the base stock and refining operations. The cloud point of so-called winter diesel fuel (#1 diesel or kerosene) is substantially lower since it contains relatively little paraffin. Fuel distributors will test the product and, if requested, may include the results in tenders and delivery receipts.
- The temperature at which a liquid loses its flow properties is known as the pour point. The pour point of diesel fuel changes according on the wax content in the fuel, which varies depending on the source of the base stock, the refining process, and the type and quantity of additives added to the fuel during refining or distribution. The difference between the cloud point and the pour point is always there, with the latter often being 2° to 20°F lower than the former. To establish the pour point of a fuel sample, certain tests must be performed. Bulk providers, as previously stated, can supply this information.
- When diesel fuel is cooled, the cold filter plugging point is a measurement based on a standardized test that indicates the rate at which it will flow through a standardized filtration equipment in a given amount of time. The CFPP is the point at which the sample fails to pass through the filter in the time allotted.
Will diesel Ungel on its own?
A variety of things can be put to a gelled tank to aid in the recovery of the fuel to its original state. Opti-Lube Gel Melt and Diesel 911, for example, are made specifically for gelled fuel. Simply fill the tank with one of these and follow the dosing directions. There’s no need to heat or mix the tank. These can take a long time to install, depending on the size and shape of the tank. The treated fuel in the tank may not be able to reach gelled fuel that is not in the tank, such as in fuel lines and filters, which is a significant constraint.
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.
