Gas Prices Sq Up

Save Money at the Pump!

Many of us are actively searching for the lowest gas price around town, but some interesting information has come to light. Compiled by an engineer with the Kinder Morgan Pipeline, we see here that there are many factors to consider when filling your tank.

  1. Only buy or fill up your car or truck in the early morning when the ground temperature is still cold. Remember that service stations have their storage tanks below ground. The colder the ground, the more dense the gasoline, when it gets warmer gasoline expands, so buying in the afternoon or in the evening…. your gallon is not exactly a gallon. In the petroleum business, the specific gravity and the temperature of the gasoline, diesel and jet fuel, ethanol and other petroleum products plays an important role.You can also view more to know more about rental cars.
  2. A 1-degree rise in temperature is a big deal for this business. But the service stations do not have temperature compensation at the pumps.
  3. When you’re filling up, do not squeeze the trigger of the nozzle to a fast mode. If you look, you will see that the trigger has three (3) stages: low, middle, and high. You should be pumping on low mode, thereby minimizing the vapors that are created while you are pumping. All hoses at the pump have a vapor return. If you are pumping on the fast rate, some of the liquid that goes to your tank becomes vapor. Those vapors are being sucked up and back into the underground storage tank so you’re getting less worth for your money, look into a check stub maker.
  4. One of the most important tips is to fill up when your gas tank is HALF FULL. The reason for this is the more gas you have in your tank, the less air occupying its empty space. Gasoline evaporates faster than you can imagine. Gasoline storage tanks have an internal floating roof. This roof serves as zero clearance between the gas and the atmosphere, so it minimizes the evaporation. Unlike service stations, here where I work, every truck that we load is temperature compensated so that every gallon is actually the exact amount.
  5. Another reminder, if there is a gasoline truck pumping into the storage tanks when you stop to buy gas, DO NOT fill up; most likely the gasoline is being stirred up as the gas is being delivered, and you might pick up some of the dirt that normally settles on the bottom.
  6. Note: If the pump repeatedly shuts off early, it could be a sign of a problem with the vapor recovery system, such as a clogged carbon canister.
