Tips on Pumping Gas Efficiently

3/26/2011

Only buy or fill up your car or truck in the early morning when the ground temperature is still cold. 

Remember that all service stations have their storage tanks buried 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. 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.

When you're filling up, do not squeeze the trigger of the nozzle to a fast mode.
 
You will see that the trigger has three (3) stages: low, middle, and high.  You should be pumping on the slow or medium modes, 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 fuel for your money.
 
One of the most important tips is to fill up when your gas tank is HALF FULL.
 
The more gas you have in your tank, the less air you have occupying the 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 every truck that we load is temperature compensated so that every gallon is the exact amount.
 
If there is a gasoline truck pumping into the storage tanks when you stop to buy gas, DO NOT fill up.
 
Gasoline is being stirred up significantly as the gas is being delivered, and you might pick up some of the dirt that normally settles on the bottom.

What Our Customers Say!
Several months ago we had a flood in our home due to a defective valve in our guest bathroom. Needless to say we came home to a disaster. We immediately contacted our agent, Linda Welborn. Right on the spot she gave us the name and phone number of a company to call (Disaster One). They came out that evening (around 11:30pm) and worked through the following morning around 6:30am. They did an outstanding job! We were so impressed with their "sense of urgency" and "expertise" we assigned all of our repairs to their company. The insurance adjuster(Erie Insurance) cut no corners when it came to replacing damaged items. They issued repair orders on things we weren't even aware we needed to look for. They too did a great job in getting everything processed quickly. It's great to have such a Professional agent who treats us like we are her only customer. I have been so impressed with her outstanding customer service that I refer many people to your agency because of the great care and attention she gives to her customers. Thank you Linda for your outstanding service! We look forward to working with you in the years to come.
