The company was foundedin 1939 by Adrian W. Yorkston, as Hardwood Fuel Company selling mill ends from lumber mills to homeowners to heat their homes. As time evolved, furnace oil became the popular fuel to heat homes. That is when Hardwood Fuel Co. became a Signal Oil distributor and changed its name to Yorkston Oil Co. Adrian’s sons’ Barney Sr. and Tom became involved in the company and soon took ownership when Adrian retired.

Signal was bought out by Enco, and eventually changed their name to Exxon. Tom retired in 1997 and Barney in 1999, leaving ownership to Barney's three sons. In 2001 Exxon and Mobil merged to become Exxon/Mobil Corp.

In January of 2009 Exxon/Mobil left the great northwest giving us the opportunity to become an unbranded distributor for the first time in the history of this company.

Today, Yorkston Oil Co., is still an independently owned and operated company in Bellingham, Washington.
