- Filling up your tank in the morning when it's cooler makes no difference in cost savings because the 35,000-gallon underground tanks do not dramatically change temperature in daily cycles.
- Larger fuel retailers turn over supply very rapidly, greatly reducing the fuel's time spent in the underground, insulated tanks.
Glossary
Ambient Temperature – Temperature of the atmosphere, outside of any fuel containers or tanks.
Automatic Temperature Compensation – At the retail phase of fuel distribution, the final selling price is adjusted according to the standard of 60 degrees Fahrenheit.
BTU - The British thermal unit (BTU or Btu) is a unit of energy used globally in the power, steam generation and heating and air conditioning industries.
Hot Fuel - Refers to expanded diesel fuel or gasoline that is sold at retail pumps at temperatures higher than the century-old government standard of 60 degrees.
At the 60-degree standard, a gallon of fuel delivers a certain amount of measurable energy, or BTU. But when expanded by higher temperatures, that same amount of fuel actually delivers less energy. The warmer the fuel, the less BTU and fewer miles to the gallons a vehicle will receive.
Rack – Refers to the wholesaling of gasoline product or the location where a fuel tanker truck picks up fuel in order to deliver to a retail location.
