About Us

KWOil was founded in 1926 as the Kelley Williamson Company.  We have since expanded to form an entire division of the Kelley Williamson Company that also serves as a “parent” to Kelley’s Markets. There are nearly 50 state-of-the-art Kelley’s Market convenience stores and fuel centers throughout Northern Illinois and Southern Wisconsin. KWOil manages and administers oils and lubricants distributed to a wide range of businesses across Illinois and Wisconsin. We also serve customers throughout the USA who demand quality products, timely service and expert product knowledge.
