About us
Martinez Refining Company (MRC) manufactures the cleanest motor fuels in the world, providing an affordable and reliable supply of gasoline, diesel, and jet fuel to the Bay Area.
Our refinery is located on 860 acres and contains 35 process units, each of which plays an important role in how we turn crude oil into fuels that help provide the highest standards of mobility in history.
Our daily workforce consists of 585 full-time employees and 300 embedded contractors. Additionally, 1,000+ Building Trades craftworkers are added during the refinery’s major maintenance activities, which we call “turnarounds.”
In 2024, MRC provided (approximately):
- 25% of the Bay Area’s gasoline supply
- 55% of Oakland and Sacramento Airports’ jet fuel supply
- 40% of San Jose and San Francisco Airports’ jet fuel supply
Martinez Refinery was built in 1915 with significant expansions made in the 1960s, 1980s, and 1990s. Today, it is a modern refinery with advanced automation, controls, and technology. MRC purchased the refinery from Shell in 2020 for $1 Billion and continues to make annual reinvestments in the site between $100 to $300 Million.

What a day! The 24th Annual MRC-MEF Run for Education brought our community together to support Martinez students and schools, and we raised $281,000!
From the Alhambra High School Marching Band and Color Guard kicking things off to runners, walkers, families and volunteers filling the streets, it was a wonderful morning in Downtown Martinez.
Here are a few photos from the day, and we'd love to see your pictures too!
Keep checking back as we'll be sharing more photos in the days and weeks ahead.

Each Wednesday Contra Costa County's Community Warning System (CWS) runs a test at 11:00 am. This is a similar test as what the community may hear on the first Wednesday of every month. The Contra Costa County Sherriff's Office operates the Community Warning System and their website states, “Sirens are tested on the first Wednesday of every month at 11:00am. For the remaining Wednesdays, a more quiet and low “growl” test is performed at 11:00am.”

The refinery runs internal tests Mondays between 11:00 am and 12:00 pm to ensure our sirens are operational. During the tests on Monday, sirens will typically be heard by our fence line neighbors and potentially beyond. Testing our sirens ensures that we run the refinery to the highest safety standards possible to protect the community, employees, and contract partners.
We have a team of dedicated employees who respond to inquiries 24 hours a day, seven days a week. We invite our neighbors to call our Weekday Phone number at 925-313-3777 or our After-Hours Phone number at 925-313-3601.

We had a record-breaking year, raising $281,000 for the Martinez Education Foundation. A huge part of that success is the Annual MRC-MEF Fairways Fore Futures Golf Tournament.
Thank you to all our sponsors, volunteers, and golfers that made the MRC-MEF Fairways Fore Futures a wonderful event: https://youtube.com/shorts/nvMphRliPKc
