The New Oils: An Update on CK-4 and FA-4

Last December, for the first time, the American Petroleum Institute started licensing two different approved heavy-duty diesel engine oils. CK-4 adoption is going largely as expected, but very few fleets are using FA-4 yet – because very few engine makers so far are recommending it.

Two Oil Categories Rolling to the Finish Line

It’s not rocket science to split an API oil-service category. But it takes lots of chemical engineering to develop and bring to market not one, but two, new heavy-duty motor oil specs in a mere five years.

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.

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?

Save Fuel, Increase Profit, Save the Planet

Is this a case of win-win? Do the new regulations limiting greenhouse gas emissions help both the environment and truck operators’ bottom lines? So it seems.

Beyond the API 'Donut:' Putting a Premium on Oil

Every fleet knows how important oil is to the proper operation of their vehicles, but how can they determine if upgrading to a premium oil makes sense for them?

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.

The Next Generation of Oils: New API oil category will help meet fuel economy/GHG regs

Three years from now, you'll see a new API diesel engine oil-service category, designed to help meet federal greenhouse gas/fuel economy standards, which have a final phase-in date set for model year 2018 trucks.

The Business Case for Synthetic Lubes

For years, some fleets have turned to synthetic engine oils for easier starts in cold-weather climates and to help them extend oil drain intervals. But if that's the only selling point you're using for synthetic lubes, it may be time for some consumer education
