To lubricate the fuel system and the upper end of the cylinders, some diesel owners like to add a little 2-stroke oil to their fuel tank. Regular engine oil is sometimes used as well. Is adding 2-stroke oil to diesel fuel safe and effective?
Is it possible to blend motor oil and diesel fuel?
Is it possible to mix diesel with engine oil? It is possible to combine diesel and gasoline engine oils. A diesel engine intended for heavy-duty applications should not be lubricated with motor oil meant for passenger cars and gasoline engines.
FUEL PUMP + INJECTOR PROTECTION
LX4 LUBRICITY EXTREME is an ultra-low sulfur diesel (ULSD) and gasoline lubricity additive. The greatest level of lubricity performance on the market, Ultra-low Sulfur diesel additive can bring even the lowest grade fuel back into specification and exceed OEM lubrication standards.
How can I make my diesel more lubricious?
Using a fuel additive designed expressly for this purpose, such as AMSOIL Diesel Injector Clean, Diesel All-In-One, or Diesel Injector Clean + Cetane Boost, is the best way to boost fuel lubricity.
AMSOIL diesel fuel additives also offer a variety of additional benefits that help diesel engines run at peak efficiency.
Is it necessary to add additives to diesel fuel?
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 usage of fuel additives.
“We do not advise Volvo truck owners to add additives to their diesel fuel.” According to John Moore, powertrain product marketing manager for Volvo Trucks North America, if additives are required, they should be added at the fuel supplier terminal.
Last year, Cummins became the first company to publicly promote 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 knows that some fuels on the market are of poor quality and do not always exceed 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, some cold-weather activities may require the use of fuel additives.
“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.
“We propose Top Tier diesel fuel because it overcomes many of the inadequacies of ASTM regulations regarding diesel fuel quality,” explains Jason Martin, manager, HDEP thermodynamics and fuel map management at DTNA. ” Top Tier is a voluntary retailing program that tackles fuel stability and lubricity, as well as detergency, water, and particle systems, all of which contribute to the fuel system’s performance being maintained over the engine’s lifetime.
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 it possible to use too much diesel additive?
It’s easy to overdo it with a high-quality diesel fuel additive. What happens if your diesel fuel is over-treated? Overdosing can result in a slew of new fuel and engine problems, ranging from clogged filters to decreased engine performance and efficiency. Don’t over-treat if you’re losing lubricity.
Is sulfur in diesel fuel a good lubricant?
Since its introduction into on-road diesel use in the United States a decade ago, ultra-low sulfur diesel (ULSD) has proven to be beneficial to the environment. Less sulfur in the air equals fewer hazardous pollutants.
However, the switch to ULSD has had certain negative consequences for diesel vehicles. The loss of lubricity is one of the most serious. The lubricating characteristics of petroleum fuel are due to sulfur, a chemical ingredient. Petroleum diesel has substantially less of the component that aids lubricity in ULSD. As a result, many fleets are investing in lubricity additives or experiencing greater engine wear. However, there is another option.
Biodiesel offers excellent lubricity properties. Biodiesel can also be mixed readily with petroleum diesel. Even as little as 2% biodiesel (a B2 blend) is added to the gasoline to provide the necessary lubricity, and greater blends help offer even more lubrication.
Which diesel additive is the 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.
Is sulphur a lubricant in diesel?
Is sulfur used as a lubricant? “Sulfur works as a lubricant in diesel,” according to the paper, “and lowering the sulfur level results in a proportional decline in the fuel’s lubricity.”
Is Lucas Fuel Treatment suitable for diesel engines?
No SOLVENTS are used in this strong blend of oils and additives. Designed to improve power and fuel mileage while lowering exhaust emissions by allowing for more complete combustion.
Lucas Fuel Treatment is designed for carbureted and fuel-injected gasoline and diesel engines. It provides your fuel system with just what it requires: a blend of extremely slick oils and additives with a high detergent action, allowing the engine to run at peak efficiency. It also cleans and lubricates the carburetor and injectors, causing the gasoline to burn more thoroughly and produce greater power while using less fuel. Lucas Fuel Treatment should be used in cars that require leaded gasoline since it effectively replaces the benefits of lead in gasoline without emitting harmful pollutants. It can be used to pass smog tests. Finally, it completely cancels out the negative impacts of low-sulfur diesel fuel.
For use in diesel motor vehicles, non-road, locomotive, and marine diesel equipment engines, Lucas Fuel Treatment meets federal low sulfur content criteria.
