Over-the-Water Fueling

Western States Oil provides dependable over-the-water fuel delivery for marine vessels, ports, and waterfront facilities. We deliver fuel directly to dock, berth, or anchorage to keep operations running without unnecessary delays.

Our experienced team follows strict safety and environmental standards, ensuring compliant and efficient fueling in marine environments. We work closely with vessel operators, ports, and facility managers to provide scheduled or on-demand service that minimizes downtime and supports continuous operations.

Reliable fuel delivery. Safe operations. Minimal disruption.

On-Site Fleet Fueling

Bulk fuel transport companies, such as Western States Oil, have tankers of all sizes that deliver to private fuel tanks on construction job sites, at farms and various businesses locations, allowing for a private gas station to fuel the fleet. Wet-hosing on-site equipment means the fuel is delivered directly from the transport tanker into the heavy machinery or large storage tanks on private property. Direct fueling to heavy machinery and private storage tanks saves time and money.

Western States Oil has the experience, equipment and resources to meet your company’s unique fueling needs. We are a large scale fuel transport company, serving the greater San Francisco Bay Area. We are also a supplier of renewable red dyed diesel which is available for all certified off-road equipment.

Remote Tank Monitoring

Remote Tank Monitoring is available to customers who can’t take the chance of running out of fuel. Western States Oil can install a monitor on your above ground fuel tank and our dispatch will monitor it’s inventory via the internet and schedule deliveries before it is too late. If you have an underground storage tank we can tie directly into your TLS system to get inventory reports too. This feature takes the worry out of your hands and also guarantees that your company is getting the best fuel price because the gallons delivered are maximized.

Some of the larger municipal fleets in the Bay Area trust Western States Oil to keep them moving, such as:
• The City of San Francisco
• The City of San Jose
• The City of Oakland
• East Bay Regional Parks
