AMSOIL Synthetic Lubricants Protect Hardworking Diesels

The term “diesel” still conjures a host of negative connotations to some: loud, smelly, smoky, dirty. Such unflattering descriptions may have been apt years ago, but those in the know realize today’s diesels no longer fit the stereotype. And judging by the numbers, increasingly more drivers are discovering the truth about diesels.

Data compiled by and Baum and Associates reveal that U.S. clean-diesel car sales jumped 25 percent during the first six months of 2014. An impressive increase, but even more so when considering the overall car market increased just 4.2 percent during the same time. Even more remarkable, increased sales have come during an economic recessionary period during which, until recently, diesel fuel prices have trended upward. 

“Clean diesel” is a term automakers use to distinguish today’s cleaner, quieter diesels from their loud and smoky predecessors. Technically, a clean-diesel engine is no different from any other diesel engine. The differences lie in the fuel they use and their sophisticated exhaust-treatment devices. 

In 1993, the United States government limited diesel fuel sulfur content to 500 ppm – known as low-sulfur diesel. In 2006, ultra-low-sulfur diesel became available, which has a maximum sulfur level of 15 ppm. By 2010, the EPA required that 100 percent of highway diesel fuel be ULSD. 

More changes to the diesel fleet came in 2007. To meet EPA emissions standards, on-road diesel vehicles model-year 2007 and later come with exhaust-treatment systems designed to reduce harmful emissions. These systems range from exhaust gas recirculation (EGR), diesel particulate filters (DPF), in-line regeneration and others. Though they all function differently, their purpose is the same. They, along with ULSD, are expected to decrease emissions from these engines by more than 90 percent. 

Turbocharged diesels already place enormous stress on motor oil. Elevated heat and shearing forces can thin the oil until it fails to provide adequate protection, leaving components susceptible to wear and failure. Sophisticated emissions-control devices on 2007-and-newer diesels make things worse. Fuel dilution from DPF regeneration or excessive idling further thins the oil, while excess soot from EGR and blow-by leads to harmful sludge formation and abrasive wear.

AMSOIL synthetic diesel oils are designed to withstand the punishment doled out by diesel engines. The complete line of AMSOIL synthetic diesel oils delivers superior protection for older and modern diesels equipped with exhaust treatment devices. They resist wear, withstand extreme heat and guard against the harmful effects of soot, such as oil thickening and sludge formation. 

AMSOIL synthetic diesel oils have you covered during heavy use and even abuse.
