A North Carolina fleet has been running a group of trucks on three different Shell Rotella oils -- a 15w-40, a 10w-30, and a 10w-30 that's been altered to provide a lower high-temp/high-shear number than is currently approved. A teardown of one of each after more than half a million miles shows virtually no difference in wear among the three engines. Learn more here. (By Deborah Lockridge, Editor in Chief.)
In anticipation of a new heavy duty engine oil API classification aimed at improving fuel economy with oils meeting lower high-temperature/high-shear viscosity standards, Shell did a field test of an experimental low HTHS-viscosity version of its Rotella engine oil. It shared the results with trade press editors on May 14, 2014. Here Howard Hill, engineer, lubricant technology, explains the results to HDT Editor in Chief Deborah Lockridge.

Gasoline in truck diesel engines can give more than 50% efficiency if the combustion process is done correctly. A modified diesel engine running on gasoline could be a way of significantly reducing truck emissions, according to research at Lund University in Sweden. New fuel efficiency standards for large trucks were announced by President Obama just last week. The method could halve fuel consumption for gasoline engines.

“Proprietary” is a magic word among truck builders. It describes components of the company’s own manufacture or design that are installed on the company’s own trucks. For truck users, this can be a good thing, because they’re designed to work specifically with a company’s other components.
