Maxum is proud to service major ports spanning the West Coast of the United States. Maxum is the largest single source lubricant blending and distribution company in the
Western United States, and the largest petroleum product supplier in the Pacific Northwest.
Since 1946, under the founding company name "General Petroleum", we have made our mark on the petroleum industry by offering quality products and services
customers have come to depend on.
Since then we've expanded our reach and our products / service offerings to include wider regions and a more diverse customer portfolio.
With the acquisition of our Rancho Dominguez, CA petroleum blending facility from Shell (Quaker State) in 2001 we've crossed the threshold
to become the largest blending and distribution company in the West. The Rancho Dominguez facility has 58 tanks, totaling over 2.6 million gallons of bulk
storage capacity, and features an in-house QC laboratory on-site.
