We sell peace of mind. Each time a tanker truck delivers fuel, gas stations are at risk. 58% of gas stations are one-store operators, who cannot afford the loss of foot traffic, headaches, and loss of public confidence. About 40% of gas stations are owned by the Petroleum Marketers, liable for damages from fuel mix-ups. On average, a tanker truck of motor fuels is sold at the almost 120,000 gas stations in the United States every 2 days.
