A Brief Biography of the late T. R. Mullen, the Formulator of the Gibraltar Compressor Oil:
Gibraltar Compressor Oil was formulated in 1972 by T. R. Mullen at the request of Glen M. Majors, a Dresser-Rand compressor design engineer looking for an improved lubricant for severe field service. In addition to its unique lubricating qualities, it was essential that the special Gibraltar formulation would combat corrosive, wet, high-pressure gases found in chemical and fertilizer plants, gas-gathering services, and refineries, and prevent deposits from forming in critical areas of the reciprocating compressors. Within a short while, two other lubricants, Gibraltar H and Gibraltar Synthetic 400 were formulated for field use.
Mr. Mullen retired as Senior Research Engineer from Cities Service Oil Company with more than 35 years' experience in formulating a wide variety of oil products, including wax and wax products, greases, and a large number of different oil formulations for a multitude of uses.
Mr. Mullen was a Phi Beta Kappa graduate of the University of Arizona with a Master's Degree in Chemistry and a Bachelor of Science Degree in Marine Engineering from the United States Merchant Marine Academy at Kings Point, New York.
A Brief Biography of Glen M. Majors: 
Glen M. Majors graduated with a Master's Degree in Mechanical Engineering from the University of Michigan, after which he served four years in the United States Navy. Upon completing his military service, Mr. Majors began working for Dresser-Rand as “Chief Design Engineer.” During his 30-year tenure with Dresser-Rand, he was involved in field-testing new equipment and modification of existing equipment. While in the field, he saw that a special compressor oil was needed to combat hydrogen sulfide, carbonic acid, and other corrosive, water-wet gases.
After retirement from Dresser-Rand, Glen Majors became a full-time reciprocating compressor consultant. He worked with many facilities to solve all types of problems experienced by plant engineers and superintendents, including design, mechanical, and technical.
In May 1991, Jim and Linda Bass purchased CES Associates, Inc., now known as Gibraltar Lubricating Services, Inc., from Glen Majors, retaining Majors as a reciprocating compressor lubrication consultant. He continued in that capacity until his death in May, 2006.
