Providing Fuel to The Pacific Northwest

Star Oilco is a Portland, OR based petroleum company that was initially pioneered in 1936 through the marketing and sales of sawdust, coal and wood. Over the years, the company began to specialize in petroleum products.

In 1984, Oilco was acquired and the company became Star Oilco and quickly grew to become one of the leading full-service, petroleum providers in the Pacific Northwest. We are your #1 choice when it comes to finding fleet-fueling solutions for your business or heating oil needs for your home or commercial residence.
