Oil Viscosity: How Low Can You Go?

To meet expected greenhouse gas/fuel efficiency standards, oil companies and engine makers have been busy developing a new standard for engine oils that will provide a new type of lower-viscosity oil to improve engine efficiency.

New Oil Standard Won't Have Adhesive Wear Test

A proposed test for adhesive wear, or scuffing, will not be a part of the upcoming new API oil standard, currently known as PC-11, and the new category is running behind schedule for implementation.

Shell Teardown Evaluates Low-Viscosity Experimental Engine Oil

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.

The Lowdown on the New Low-Viscosity Oils

Exactly what is this "high-temp, high-shear" viscosity engine oil standard in the works for the next round of EPA emissions standards, and what are engine makers doing to make sure engines will still be well protected?

Oil & Gas Producers Join Truckers for Improved Road Safety

Oil and gas companies have joined forces with the trucking industry to promote improved road safety and traffic management in heavily traveled producing areas like the Eagle Ford in south central Texas, the Marcellus region in the Northeast and the Bakken in the upper Midwest.

Going Green With Re-Refined Oil

What are you doing with the spent oil from your engines? Most fleets are reusing it somehow, perhaps by burning it in special furnaces to heat the shops or selling it to a recycler who'll put it to other uses. Drain oil was once dumped or given away, but since the rise of petroleum prices on world markets, it now brings as much as 95 cents a gallon.
