Are we ready for next generation lower High Temp High Shear oils? - by Torque

Monthly engineering blog sponsored by Texaco.

While ACEA (European Automobile Manufacturers’ Association) has yet to publish its next level specification requirements, future legislation is likely to demand better fuel efficiency to meet more stringent emissions controls. One way to make an engine more fuel efficient is to make it more thermally efficient, but what are the potential issues surrounding this development?

When an engine runs at a hotter temperature, so does the oil lubricating it, making protection more challenging. To combat this, next generation lower High Temp High Shear products will need to tread a fine line between the legislator’s desire for improvements in fuel economy and the levels of component protection and long engine life expected by OEMs (Original Equipment Manufacturers) and operators.

In addition, oils with lower High Temp High Shear viscosity, open up concerns about backwards compatibility in older engines.

With PC-11 coming into force in North America at the end of 2016 are we likely to see the introduction of two diesel engine oil standards at the same time as per API CK-4 and FA-4? Commercial Marketing Manager at Chevron, Dave Spence, thinks that is unlikely but a new lower High Temp High Shear specification will be added. “Oil compatibility issues will require fleet managers to be more knowledgeable than with past categories. We are likely to see an increased fragmentation of oil types, necessitating stricter adherence to OEM recommendations than in previous generations.”

But, says Spence, “while this may appear confusing initially, it brings with it greater opportunities than ever before to lower costs and emissions by sourcing the right product for individual applications.”
