The company's product and service portfolio spans bulk fuel delivery (diesel, renewable diesel, 87/89/91 octane gasoline, red-dyed agricultural diesel, racing fuels), lubricants (Chevron, Havoline, Delo, BioBlend), DEF, coolants, filters, and fuel storage tanks (50 to 10,000 gallons) sold and rented through three Dewar Depot retail locations. Physical infrastructure is anchored by eight Pacific Pride cardlock fueling sites (operated as a local Pacific Pride dealer with network access to 1,300+ commercial fueling locations in the US and Canada and 40,000 Fuelman-affiliated sites), HazMat-certified bulk delivery trucks, and over 200,000 gallons of emergency fuel inventory. Service revenue is generated through transaction-based sales of fuel and lubricants, supplemented by technical services (equipment installation, repair, inspection, regulatory compliance for California fuel storage) and a structured Chevron LubeWatch oil analysis program run through ALS Tribology laboratory, with installed TankScan wireless tank monitoring systems as a recurring touchpoint on customer sites.
