Truck Lubricants Guru Slipping Into Retirement

SAN RAMON, CA. — After nearly 40 years in the lubricants business, Chevron’s well-known consulting scientist for its Delo heavy duty engine oil and a man who helped establish heavy duty engine oil categories has decided to retire at the end of June.

The move by James “Jim” McGeehan comes after he began his career with Chevron in 1976 as a research engineer.

During his tenure, he has served as the global manager of diesel engine oil technology and was responsible for all global heavy-duty engine oil development and coordinating all diesel engine programs for Chevron’s lubricants businesses, according to the company, including leading the team responsible for the development of Chevron Delo 400.

“I would like to thank Jim for his dedication, passion and many contributions and mentorship to our company, personnel and industry over the past four decades. He has been a leader in our lubricants formulating team and has set a high standard for all of us to follow into the future” said Brian Stripling, general manager brand, technology and original equipment manufacturer, Chevron Products Co.

McGeehan also served as chairman of the ASTM Heavy-Duty Engine Oil Classification Panel since 1987, and he and his team have been responsible for establishing progressively improved heavy duty motor oil categories that helped increase engine durability and reduce emissions.

He successfully led the introduction of seven categories from API, CE through CJ-4, and in 2002 was selected “Person of the Year” by Lubricants World. He has also been involved in final development of the Proposed Category 11 (PC-11) requirements that take effect in late 2016. 

Taking over for McGeehan will be Shawn Whitacre, senior staff engineer. His career spans nearly 20 years focused exclusively on research and engineering dealing with heavy-duty engine lubricants, fuels, and materials.

Before joining Chevron in 2013, Whitacre spent 12 years leading global fluids and materials engineering activities for Cummins. He also spent five years conducting lubricant, fuel, and emission research for the Department of Energy’s National Renewable Energy Laboratory in Golden, CO.

At Chevron he is primarily responsible for product formulation of the Delo brand of heavy duty engine oils and is currently the lead formulator responsible for development of Chevron’s PC-11 product line upgrade.
