Tips on filling up your gas tank

Disclaimer: I’m not sure how true these are. I honestly just ripped this off other blogs (and a pretty common information circulating in emails). But since gasoline prices are at all time high, we can desperately try anything that can save us gas. So, Here are some tricks to help you get your money’s worth.

1. Fill up your car or truck in the morning when the temperature is still cool.

2. Remember that all service stations have their storage tanks buried below ground; and the colder the ground, the denser the gasoline. When it gets warmer gasoline expands, so if you’re filling up in the afternoon or in the evening, what should be a gallon is not exactly a gallon. In the petroleum business, the specific gravity and temperature of the fuel (gasoline, diesel, jet fuel, ethanol and other petroleum products) are significant.

Every truckload that we load is temperature- compensated so that the indicated gallonage is actually the amount pumped.

A one-degree rise in temperature is a big deal for businesses, but service stations don’t
have temperature compensation at their pumps.

If a tanker truck is filling the station’s tank at the time you want to buy gas, do not fill up; most likely dirt and sludge in the tank is being stirred up when gas is being delivered, and you might be transferring that dirt from the bottom of their tank into your car’s tank.

3. Fill up when your gas tank is half-full (or half-empty), because the more gas you have in your tank the less air there is and gasoline evaporates rapidly, especially when it’s warm. (Gasoline storage tanks have an internal floating ‘roof’ membrane to act as a barrier between the gas and the atmosphere, thereby minimizing evaporation. )

4. If you look at the trigger you’ll see that it has three delivery settings: slow, medium and high. When you’re filling up do not squeeze the trigger of the nozzle to the high setting. You should be pumping at the slow setting, thereby minimizing vapors created while you are pumping. Hoses at the pump are corrugated; the corrugations act as a return path for vapor
recovery from gas that already has been metered. If you are pumping at the high setting, the agitated gasoline contains more vapor, which is being sucked back into the underground tank, so you’re getting less gas for your money.

“Swerving is NOT a violation”, and other petty MMDA abuses

This information is circulating on emails lately. I find this very informative especially if you drive along Metro Manila and has been abused by MMDA, MAPSA and other local traffic kotong operatives.. It’s originally entitled “How you can challenge petty abuses of MMDA personnel…

I just reached my limit last week-end, and decided to take action against the abusive MMDA enforcers. I basically called up the MMDA head office and inquired from the Personnel Officer, Antonio Pagulayan, to clarify their policies. Here is what I got.

If any of these abuses seem familiar to you, Mr. Pagulayan has asked that you call either the MMDA hotline (136) or call the METRO BASE at 0920-938-9861 or 0920-938-9875 and ask for an Inspectorate. They will send inspectors to the place where these MMDA officers are extorting, even while you are arguing out of your apprehension.

MMDA in the Middle of EDSA1. MMDA officers are not allowed to group together in order to apprehend.

They are not even allowed to stand together in groups of 2 or more. The only time they are allowed to work together is for special operations (probably when they apprehend groups of buses for smoke belching);

2. Swerving IS NOT a traffic violation. Moving one lane to the left or right is not swerving, no matter where on the road you do it. And it is even less of a violation when you do it with a signal. Swerving is defined as shifting 2 or more lanes very quickly. So you can argue your way out of this, and call the Metro Base for help;

Buses outside the Yellow Lane3. Sadly, using the yellow lane is a traffic violation and will get you a ticket. However, buses are really not allowed to go out of the yellowlane, so if you see selective apprehension of private cars only, you may complain;

4. MMDA has confirmed that your license MAY NOT BE CONFISCATED at a traffic apprehension. The only time they can do so is if you are part of an accident, or it is your third violation and you have not settled your fines yet. They are only allowed to give you a ticket, which you can contest. He recommends actually receiving the ticket in some instances, so that you can report the officer who did it.

Also, you are free to ask any of these officers for their “mission order”, which is written by their supervisor. If they apprehend you for a violation that is not in their mission order for the day, you can report them and they will receive disciplinary action.

So go out and enjoy! And drive safely!!!
