With the recent fuel price adjustment on April 17th, petrol prices in Vietnam have continued to rise, with RON 95-III “jumping” to VND 25,230 per liter, an increase of VND 410 per liter compared to the previous adjustment period. On January 4, 2024, the price of RON 95-III petrol was only at VND 21,910 per liter. Therefore, petrol prices have increased by VND 3,320 per liter since the beginning of the year. Also, during the period from January 4 to April 17, Diesel 0.001S-V price has also increased from VND 20,340 per liter to VND 22,050 per liter.
According to Mr. D. (living in District 8, HCMC): “Filling my VinFast Lux SA with 80 liters of petrol at the beginning of January only cost about VND 1.75 million. At that time, the price of RON 95-III petrol was VND 21,910 per liter. I recently filled up with petrol on April 18th, also with 80 liters, but it cost up to VND 2.02 million, an increase of about VND 270,000 compared to before. The rising petrol prices have caused my petrol expenses to increase rapidly”. As someone who uses a car for daily commuting, the increase in petrol prices has significantly impacted Mr. D’s vehicle operating costs, and car owners in general.
A renowned automotive expert in the UK shared with The Sun tips and tricks to help drivers operate their vehicles most efficiently, saving fuel and significantly reducing operating costs.
Most car users do not pay much attention to adjusting gears and observing the tachometer while driving, but these are important factors in saving fuel. The expert recommends that the most fuel-efficient way to drive is to use the highest gear possible and maintain a steady speed.
Changing the habit of driving in the highest gear and maintaining a steady speed not only saves fuel but also helps the engine operate more efficiently. Furthermore, significantly reducing hard acceleration and rapid speed increases can reduce fuel consumption by up to 20%. Instead, we need to change the habit of applying force to the accelerator pedal, gently and gradually pressing the gas pedal to help the car accelerate smoothly.
Many users will not be aware of how gear shifting affects fuel consumption. Driving efficiently involves not only which gear the driver is using but also managing gears based on speed and maintaining appropriate engine RPM.
When driving a manual transmission vehicle with a gasoline engine, the driver should shift gears before the engine speed reaches 2,500 rpm. For diesel engines, the driver should shift gears before the engine speed reaches 2,000 rpm.
For vehicles with automatic transmissions, most sensor chips will automatically shift gears within a pre-calculated RPM range. The user can also manually intervene through the paddle shifters behind the steering wheel or shift to manual mode on the gear selector.
When driving outside of highways or national roads with light traffic, drivers should also travel at a steady speed, shift to the highest gear, and adjust the engine speed to the lowest level, usually around 1,500-1,800 rpm. This is an effective fuel-saving tip that has been recorded on a mid/small MPV with a fuel consumption of 4.3L/100km.
During times of high fuel prices, applying tips and tricks to operate vehicles more fuel-efficiently will also help car users save a considerable amount of money.
