Saving Gas Part 2: Prevent The “Vapors” At The Pump
Friday, July 11th, 2008
One of our bargain hunters, who is an expert in the petroleum industry, sent these suggestions on how to save money at the pump, and MarkdownMom would like to share them with you:
TIPS ON PUMPING GAS
1. 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. As it gets warmer gasoline expands, so buying in the
afternoon or in the evening….your gallon is not exactly a gallon.
2. 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. In slow mode you should be pumping on low speed,
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
other 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.
3. Fill up when your gas tank is HALF FULL or HALF EMPTY. 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.
4. 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. Hope this will help you
get the most value for your money.
5. Lessen creation of vapors by parking in the shade, not in the sun. Heat makes the molecules speed-up and increases evaporation. Plus parking in the shade prevents sitting on a “hot seat!”

Recently, a local television network covered a story about an attempt to competitively attack high fuel prices by using hyrdrogen fuel cells for your car’s engine.
Recently,
This year’s
Markdownmom’s Twin Cities tour has begun. Today MDM visited the Easter Seals Goodwill store located in St. Paul, MN.. This thrift store is one of the contributors to the s
because of this store’s connection with the national auction site. However, there were some deals on home appliances such as a BreadMan bread machine NIB for under fifty dollars and a medium cuisinart only missing its feeding tube for under five dollars. Also, selected designer items, electronics, tools, and antiques are held under glass to bid on in a silent auction. The Easter Seals store also has a large book and record collection. College students can find some inexpensive furniture pieces and art work for their apartments or dorm rooms. 

MapQuest® says turn left onto 77, but there is no left exit and you know that the mall is south of the highway you are on, so it makes sense that the exit should be on the right side. But the online directions say Left, and you are trying to merge and find the exit at the same time. 1,2, 3 cars are honking from behind you because you are going slow, yeah, yeah, I know, but–well that’s okay, they can go into the middle lane Oh, oh, now the semi is putting on its brakes simultaneously honking and screeching. The passengers in the car are yelling and it’s indecipherable, something about their "…lives flashing before their eyes." Well, the &*%# directions said left, now you make the executive decision to get over to the right lane and look for an exit.–remember Mapquest® does have that disclaimer. Aha! You knew it –there is the exit to #77 and the mall, and it is on the Right, going south! You knew it!
