Cox Petroleum Transport

What Cox Petroleum Transport does

Cox Petroleum Transport is a privately held, family-owned third-party logistics carrier specializing in petroleum product transportation. Founded in the 1960s by Hiram and Mary Cox in Bakersfield, California and incorporated in 1971, the company now operates 150 tanker trucks across 9 terminals in California with a separate fleet of 15 OTR trucks serving 48 states and Canada. It runs 24/7/365 with a central dispatch operation in Bakersfield, delivering gas, diesel, ethanol, lube oils, and chemical products for major oil and energy customers including Chevron, ExxonMobil, Phillips 66, Marathon, Shell, Kroger, and Flyers Energy.

Cox operates two core service lines: California petroleum transportation (regional hauling via 150 trucks from 9 terminals) and Over the Road services (long-haul lube oil and chemical transport via 15 trucks). The technology stack is conventional fleet-management hardware - GPS, forward and inward-facing cameras, rollover stability systems, speed monitoring, and monthly driver scorecards - combined with a certified defensive-driving training program. Cox has begun running renewable diesel in its fleet as an early-stage alternative-fuels capability. There is no software product, API, or proprietary platform; all technology is internally deployed to support hauling operations.

The business model is transactional fee-for-service transportation under contracts with enterprise energy and retail customers. Go-to-market is relationship-driven, with terminal managers handling local accounts and 3PLs (Penske, Ryder) coordinating OTR load boards for fuel-company clients. Distribution is direct via owned assets (drivers, trucks, terminals), with OTR load coordination supplemented through 3PL channel partners. Jeremy Mairs completed a family succession to 100% ownership in 2024, and a professionalized leadership team (CEO/CFO/COO/EVP/VP IT/VP Safety) now manages the operation alongside 200+ employees.
