“You get what you pay for” – This saying always holds true, especially for drivers. Powerful trucks carry more goods, but they also consume a significant amount of fuel. So how do you know if your “workhorse” is guzzling too much gas, and how can you maximize fuel efficiency? Today, Hanoi Trucks will reveal incredibly simple yet effective ways to check your vehicle’s fuel consumption!

Why Check Your Vehicle’s Fuel Consumption?

Every driver has probably heard a story about a truck that “drinks gas like water.” Excessive fuel consumption not only leads to financial waste but also poses a risk of engine damage, endangering the driver and others.

According to Nguyen Van A, Technical Director of ABC Auto Repair Shop, “Regularly checking your vehicle’s fuel consumption not only helps you control operating costs but also helps detect potential engine problems early, thereby extending the life of your vehicle.”

Simple and Accurate Ways to Check Fuel Consumption

1. The Traditional Method: “Full Tank – Drive – Full Tank”

This method is as easy as pie and widely used by drivers. Here’s how it works:

Step 1: Fill up the tank. Make sure to tell the attendant to fill it until the fuel overflows.
Step 2: Record the current mileage on the odometer.
Step 3: Drive normally for a specific distance (about 100-200km).
Step 4: Fill up the tank again. Ensure you use the same type of fuel and fill up at the same gas station as the first time.
Step 5: Record the current mileage on the odometer.
Step 6: Calculate the fuel consumption.

Formula:

Fuel Consumption (liters/100km) = (Liters of fuel filled the second time) / (Distance driven) x 100

Example:

First fill-up, odometer reading: 10,000 km.
Second fill-up, odometer reading: 10,150 km, fuel filled: 10 liters.
Applying the formula: (10 liters) / (10,150 – 10,000) x 100 = 6.67 liters/100km

Frequently Asked Questions About Checking Fuel Consumption

Carrying heavy loads definitely increases fuel consumption. Experienced drivers suggest that exceeding the allowed load capacity can increase fuel consumption by up to 30%.

How can I minimize my vehicle’s fuel consumption?

Regular maintenance: Change oil, air filter, fuel filter, etc. on time.
Drive smoothly: Avoid sudden acceleration and braking.
Check tire pressure regularly: Underinflated tires also contribute to higher fuel consumption.
