Established in Kirkland, Washington in 1947, Overlake Oil Inc has grown from a small home heating oil and fuel reseller to a full service petroleum distributor serving the greater Puget Sound area. We offer: We have been a Shell Lubricants distributor since 1961 and added the Calflo heat transfer product line from Petro-Canada Lubricants in 1996. Both suppliers are renowned for premium quality products worldwide. We experience excellent technical support with both suppliers. Requirements for products outside our primary lines are filled with quality items from a wide variety of other manufacturers. Solutions, engineered systems and service are the means by which we distinguish our company from the crowd and elevate our products above commodity status. Service starts with having knowledgeable people answering phones, taking orders and handling inquiries. Service entails trained field service and delivery personnel, and modern equipment to assure deliveries when you need them. Our commitment is to become an integral part of your team. We will work with you to look for ways to help your business run more smoothly and profitably.
