Clients Say

  • “Maxum is our go-to company for all of our lubriant needs. They offer the most consistant, reliable service which our company has come to depend on. We consider our relationship one of mutual benefit but it is apparent through the demonstation of the Maxum culture that their customer's needs come first. ”
    John Dunlop, Penzoil Manager
  • “Maxum's service is unmatched. There is no other company that can do what they do... servicing the entire West Coast, making deliveries to marine vessels, and with the most experienced marine drivers and tankermen in the business. They are also one of only a few company's that both blend product as well as deliver it to the vessels or work-sites.”
    Jake Aguilar, Exxon Representative
