Avoid Filling Your Tank Completely
Similar to budgeting a specific amount for gas, many people tend to ask for a “full tank” at the station. However, it’s best to avoid doing so as it may provide an opportunity for station attendants to scam you.
The issue arises from the use of automatic gas nozzles with a mechanism that sucks the gas back into the pump. When the gas reaches a certain level and touches the tip of the nozzle, it stops the pumping action to prevent overflow. This means you’ve paid for gas that never made it into your tank without realizing it.
The Best Time to Fill Up
The ideal time to fill up your tank is early in the morning. After a cold night, the gas will have contracted, so you’ll get a more accurate amount for your money.
On the other hand, if you fill up at noon when the environmental temperature is higher, the volume of the gas expands, resulting in a significant reduction in the actual amount of gas you receive.
Don’t Buy Gas by Amount
Buying gas by amount, especially round figures like VND 20,000, 30,000, or 50,000, can make it easier for station attendants to scam you due to a tactic called “jumping amounts,” which customers often fail to notice. The programs on the gas pumps are designed to cheat based on the amount of money.
To avoid being scammed at the pump, buy gas by the liter instead of the price. When filling up, instruct the attendant to give you 1 liter, 2 liters, etc., instead of a specific amount of money. To ensure an accurate measurement, wait for the gas to reach the red line before filling up.
Follow the Lead of Taxi Drivers
It’s advisable to fill up at stations frequented by taxi or truck drivers. This is a handy tip for finding a reliable gas station.
Taxi and truck drivers are constantly on the move, and they gain extensive experience regarding gas and know which stations are trustworthy, offer consistent quality, and never engage in fraudulent activities.
Pay Attention and Compare
If you’re traveling a fixed route and always filling up at the same place, buy a set amount of gas and check your car’s gas gauge to compare with subsequent fill-ups and other stations.
Be Vigilant When Buying Gas
First, you can spot any suspicious behavior by station attendants. Second, you’ll know whether the gas meter has displayed the correct amount or if there has been any “jumping” of numbers. Some stations employ a tactic of extending the gas hose to make it harder for customers to observe the meter, so stay alert.
