Amsoil Diesel Oils Provide Maximum Shear Stability

 

Hard-working diesel engines present a serious challenge to the lubricants that protect them. Tight clearances and intense pressures can generate enough force to tear apart the molecular structure of the oil, causing permanent viscosity loss. Permanent viscosity loss is termed "shear" and leads to accelerated equipment wear, oil consumption and deposit formation.

 

Shear stability measures a lubricant's ability to withstand shearing forces without degrading to a lower viscosity. To meet CJ-4 requirements for shear stability, the American Petroleum Institute (API) requires diesel oils to pass the Kurt Orbahn 90-Cycle Shear Stability Test.

 

Resisting shear and maintaining protective viscosity in the harsh operating conditions of diesel engines is challenge enough for many diesel oils, but maintaining viscosity in the face of fuel dilution is another challenge altogether. Factors such as frequent starts, excessive engine idling, short trips and cold weather have contributed to moderate levels of fuel dilution in diesel applications for years, while recent issues with emission systems have brought the fuel dilution problem to a whole new level.

 

For example, AMSOIL has documented increasing fuel dilution levels in 2007-2009 Caterpillar C13 and C15 on-highway engines. There are many possible causes, including problems with a unit injector or leaking seals. Another cause of fuel dilution is new emission systems using in-cylinder post-fuel injection, a process most 2007-2010 light-duty GM, Ford and Dodge diesel pickups use to regenerate the diesel particulate filter.

 

Because diesel fuel is a natural solvent, it causes a multitude of problems when it contaminates the oil, including reduced oil viscosity, reduced oil film strength, increased engine wear (particularly in the cylinder/ring area), increased volatility, weakened lubricant detergency, accelerated lubricant oxidation, varnish formation, acid formation/ corrosion and low oil pressure.

 

The most notable problem associated with increased fuel contamination is reduced viscosity and the corresponding effect it has on oil performance. When combined with shearing conditions, as little as 4 percent fuel dilution is generally enough to reduce an oil's viscosity to less than the specified viscosity grade.

 

AMSOIL sent five competitive synthetic CJ-4 5W-40 diesel oils to an Kurt Orbahnindependent laboratory for shear stability testing. Knowing the tough environment that diesels present to lubricating oils, AMSOIL doubled the standard Kurt Orbahn 90-cycle test and had the oils tested for 180 cycles. Samples were then contaminated with 2 and 4 percent ultra low sulfur diesel (ULSD) fuel. As the graph shows, even after being shear tested for twice the industry standard and contaminated with 4 percent fuel dilution, AMSOIL maintained viscosity and was the only oil to stay within an SAE 40 viscosity rating. As other oils lost viscosity due to shearing forces and fuel dilution, their ability to protect against wear was jeopardized.

 

AMSOIL Premium Diesel Oils are formulated with an ultra shear stable polymer system that maintains viscosity better than inferior products. Testing proves that AMSOIL provides unsurpassed shear stability, offering better viscosity control than competitive oils.

 

Even though recent fuel dilution issues forced AMSOIL to adjust its Premium API CJ-4 Synthetic Diesel Oil drain interval recommendations in 2007-2010 Dodge 6.7L, Ford 6.4L and GM 6.6L light-duty turbo-diesel pickups and 2007-2009 on-highway Caterpillar C13 and C15 engines to the manufacturer- recommended drain intervals, AMSOIL Premium Diesel Oils remain the premium choice for diesel applications. AMSOIL Premium Diesel Oils resist viscosity loss from both shearing forces and fuel dilution to maintain their protective film strengths, providing superior protection to all diesel engines.

 


AMSOIL DIESEL OIL API CJ-4

OUTPERFORMS IN FIELD STUDY

 

Premium API CJ-4 Synthetic 5W-40 Diesel Oil

With the help of Duluth, Minn.-based refuse hauling company Nordic Waste, AMSOIL put its Premium API CJ-4 Synthetic 5W-40 Diesel Oil (DEO) and four competing API CJ-4 diesel oils to the test. The objective was to prove the AMSOIL product's superior performance in Total Base Number (TBN) retention and shear stability, two characteristics that correlate to extended service life and enhanced wear protection. Results show that AMSOIL Synthetic 5W-40 demonstrated excellent TBN retention and was the only oil to remain within its specified viscosity range throughout the test interval.

 

Field Study Parameters

The five oils were consecutively tested in the same 2006 International 7400 rear-loading refuse hauler practicing drain intervals of 300-plus hours. Oil samples for testing were drawn every 50-75 hours. The vehicle was subjected to hauling up to 22,000 pounds of refuse up and down the steep hills of Duluth 12 hours per day. It encountered frequent stops and red-lined starts and maintained extended red-line operation during the process of unloading.

 

Placing further strain on each oil, the truck's 7.6L Navistar DT466 engine employs a hydraulically actuated, electronically controlled (HEUI) system that uses engine oil pressure to operate the fuel injectors. HEUI systems can raise oil pressure to as high as 3,500 psi, shearing less robust oils. Once sheared, permanent viscosity loss results, leading to increased volatility and oil consumption, deposit formation and increased engine wear.

 

Results - Total Base Number

Higher TBN levels well into service indicate increased levels of the additives responsible for neutralizing acids and dispersing soot. Oils that demonstrate higher TBN levels over longer periods are capable of providing increased protection throughout extended drain intervals.

 

As chart 1 shows, AMSOIL Synthetic 5W-40 was a top-performing oil in the area of TBN retention. It is important that the slope of the TBN trend line be gradual and span the entire life of the oil. While some oils experienced sharp declines, indicating poor performance, AMSOIL Synthetic 5W-40 maintained high TBN levels throughout the drain interval to provide effective engine protection.

 

Results - Shear Stability

AMSOIL Synthetic 5W-40 Diesel Oil outperformed the competing oils in the area of shear stability (chart 2). Even after 371 hours in service, it was the only oil to remain within the intended viscosity range, measuring 12.5 centistokes (cSt). In contrast, all four of the competing oils sheared out of grade before 168 hours of operation, with the Chevron and Valvoline products shearing out of grade prior to 100 hours. AMSOIL Synthetic 5W-40's increased shear stability allows for superior wear protection and long-lasting engines.

 

Amsoil Diesel Oil Study

Balanced Formulation

As the test results show, today's stricter emissions regulations and advanced engine technologies make engineering a diesel oil that balances TBN retention with shear stability a serious challenge. For example, while Valvoline Premium Blue Extreme demonstrated TBN retention on par with AMSOIL, its viscosity after 93 hours was lower than the viscosity of AMSOIL Synthetic 5W-40 after 371 hours. Similarly, Shell Rotella T6 maintained viscosity well but was the poorest-performing oil in the area of TBN retention.

 

AMSOIL Diesel Oil - Premium API CJ-4 Synthetic 5W-40 resists viscosity loss and provides superior TBN retention throughout drain intervals up to three times original equipment manufacturer recommendations, or longer based on oil analysis. It allows operators to realize increased engine protection throughout extended drain intervals for longerlasting engines, reduced downtime and maximum cost savings.
