We’re bringing you another great article on the importance of using a diesel fuel additive for proper diesel injector lubrication. Note this time we compare AMSOIL Diesel Injector Clean to using marine two stroke as a supplement. You will see below that AMSOIL is superior to all products tested.
Note: this article appeared in the August 2019 issue of the AMSOIL Dealer Magazine.

AMSOIL Diesel Fuel Additives are your best choice for increase fuel lubricity

Adequate diesel fuel lubricity is essential for protecting the highly engineered components in modern diesel engines, particularly high-pressure common-rail (HPCR) engines, which are subject to increased wear and deposits that interfere with an optimum spray pattern, reducing power and fuel economy. Many diesel owners add two-stroke oil to their fuel for added lubricity. AMSOIL delivers a better solution that provides additional benefits.
ULSD Provides Less Lubricity Diesel fuel has traditionally had high lubrication properties, but the desulfurization process that allows fuel to meet modern ultra-low-sulfur diesel (ULSD) requirements also strips it of organic compounds responsible for lubrication. Although the ASTM D975 standard for diesel fuel provides a minimum level of lubricity, it’s not as much as the Engine Manufacturers Association (EMA) has called for.
To meet government mandates for reduced emissions, nearly all diesel fuel sold in North America is ULSD, which contains a maximum of just 15 ppm sulfur, compared to traditional diesel fuel that contained up to 5,000 ppm prior to EPA regulations taking effect in 2006. ULSD is also compatible with modern exhaust treatment devices, such as diesel particulate filters (DPF), that also help reduce emissions.
The Two-Stroke Oil Remedy
Because lost fuel lubricity and the expenses associated with fuel-pump and injector replacements are serious concerns among diesel enthusiasts, some have adopted the practice of adding a little two-stroke oil to the fuel to replenish the lost lubricating properties. While this is generally a safe practice, it’s not recommended. Because all two-stroke oils are different, it’s a guessing game regarding how much oil is required to achieve a lubricity benefit. Using too little may not provide any benefit, while using too much may violate EPA laws regarding ash content.
AMSOIL – The Superior Remedy
AMSOIL Diesel Fuel Additives The best way to increase fuel lubricity is to use a fuel additive designed specifically for this purpose, like AMSOIL Diesel Injector Clean, Diesel All-In-One or Diesel Injector Clean + Cetane Boost. These additives also provide specific additional benefits designed to keep diesel engines operating at top performance.

Lubricity Test The ASTM D6079 High Frequency Reciprocating Rig (HFRR) lubricity test simulates wear in high-shear conditions, measuring fuel lubricity by rubbing a steel ball on a plate in a bath of fuel and measuring the wear scar. Independent testing reveals Diesel Injector Clean provides superior fuel lubricity over untreated fuel and fuel treated with two-stroke oil.

Use AMSOIL Diesel Fuel additives for: Better lubricity • Clean fuel system • Avoid EPA violations

AMSOIL Diesel Fuel additives are available in a variety of package sizes from 8oz, 16oz, 64oz, 5 gallon pails and 55 gallon drums. We have discounted pricing also available for preferred customers and commercial users like fleet owners, off road/construction and farming/agriculture See the “AMSOIL Buy Wholesale” page
We recommend using some sort of diesel fuel additive/supplement in each and every tank to provide the best protection for your diesel fuel system to include injectors, injection pump as well as keep your combustion chamber and injectors as clean as possible.
