Dion & Sons in Santee's Woodside Avenue industrial corridor operates a petroleum distribution depot supplying diesel, unleaded gasoline, propane, and race fuel across San Diego County. The facility is one of six Amber Resources distribution hubs in Southern California, channeling bulk fuel deliveries across the same Mission Gorge Road commercial spine anchored by Five Star Express Car Wash. An on-site CFN and Pacific Pride cardlock system enables commercial drivers to fuel using fleet card credentials without attendant scheduling requirements. The warehouse stocks Shell, Petro-Canada, and Safety-Kleen lubricant lines for independent repair shops throughout Santee's Cuyamaca Street corridor, where CARB-certified emissions testing at Smogs N Tags creates steady demand for engine oil and transmission fluid replenishment. Founded in 1930 as Amber Lubricants to serve Southern California's oilfield drilling operations, the company now runs two delivery trucks on recurring weekday routes from this Santee hub covering the full East County San Diego territory.
