A 1936 discovery of an oil field in Kettleman City, California, led to the production of RPM Motor Oil. The oil field contained a waxy type of crude oil that allowed the manufacture of a parafin-based oil that offered good mileage and an ability to withstand the effects of high heat.
Thank you Curt at The Poor Mans Museum for the above photo...
DELO, an acronym for Diesel Engine Lubricating Oil, was developed in 1934 in conjunction with Catepillar's new high speed diesel engines.
Further advances in technology helped Socal lead in the lubricating oil industry. RPM DELO Special Motor Oil, allowed US Navy submarines triple their cruising range during WW II, by reducing wear and keeping the diesel engines cleaner.
Just a note: Socal, showed their support of the allied forces efforts, during WW II, by displaying wings on their Chevron logo. Here is a shot of my G&B 96C, currently undergoing restoration.
This tradition was carried on well into the 1960s. I'll have more on Chevrons contributions to the war effort soon...
