However, there’s a small but crucial habit that most drivers overlook: After refueling, don’t rush to hit the accelerator; instead, ask the attendant one important question: “Has the pump been reset to zero?”

Why Ask This Question?
You may not be aware, but the fuel quantity gauges on the pumps can malfunction or, worse, be tampered with. After each refueling session, the system needs to be reset to “0000” to ensure that the amount of fuel you receive is accurate from the start.
If the gas station attendant doesn’t reset it to zero, they might be starting from a number left over from the previous customer. This could cost you tens or even hundreds of thousands of dong, depending on your vehicle’s fuel capacity and the price of gasoline.
Real-Life Incidents
On various automotive forums, numerous individuals have shared their experiences of being cheated at dishonest gas stations. Some have reported that when requesting to fill up 50,000 VND worth of fuel, the gauge only increased from 3,000 to 53,000, indicating they only received 47,000 VND worth of fuel.
If customers aren’t vigilant, it’s easy to fall prey to such tactics without realizing it. This is an old trick, but it’s still being employed at some less reputable stations.
A Small Question, A Big Benefit
By asking, “Has it been reset to zero?” you’re signaling to the attendant that you’re closely monitoring the process and understand the procedure. This showcases your intelligence as a consumer, prompting them to be more careful and honest in their dealings.
Additionally, this simple inquiry serves as an indirect reminder, fostering a habit of adhering to the proper refueling protocol, thus safeguarding the interests of both yourself and subsequent customers.
Other Notes When Refueling
In addition to asking about the pump’s reset status, keep the following tips in mind to avoid any losses:
- Pay attention to the digital gauge on the pump from the beginning. If it doesn’t start from 0000, request a reset and refill.
- Opt for larger, more reputable gas stations, preferably those belonging to well-known brands like Petrolimex or PV Oil.
- Stay by the pump and observe the refueling process. Avoid sitting in your car or wandering off.
- Refrain from refueling during the hottest part of the day, as higher temperatures cause gasoline to evaporate more quickly, potentially resulting in less fuel for your money.
A simple question, “Has it been reset to zero?” can protect you from fraud, safeguard your finances, and assert your status as a savvy consumer. In an era where every expense must be carefully calculated, don’t let complacency lead to unnecessary losses due to petty tricks at the gas pump.
Remember to ask next time you refuel—you have nothing to lose and everything to gain!
