Attention all drivers! The domestic refined oil product prices are set for an adjustment at 24:00 on July 17. The statistical period for this price change, spanning 10 working days, has now reached 80% completion. Influenced by a significant recent surge in international oil prices, the upward pressure on domestic fuel costs has intensified. The crude oil change rate has already reached 2.79%, indicating a projected price hike of 170 yuan per ton. Converted to a per-liter basis, this translates to an increase of 0.13 to 0.15 yuan per liter for both gasoline and diesel.
While filling up at lower prices to save money is certainly beneficial, paying attention to safety details and avoiding damage to your vehicle during refueling is even more crucial than saving a few dollars. Here are some key tips to consider.
Refueling at Dawn or Dusk is Most Cost-Effective
Since gasoline is sold by volume rather than weight, the principle of thermal expansion and contraction comes into play. Gasoline expands in volume during the hot midday hours and contracts in the cooler morning or evening. Therefore, refueling during the cooler parts of the day means you get more mass of fuel for the same volume, making it more economical. While some may not mind the difference, for daily drivers, these small savings can accumulate significantly over time.
Avoid Filling the Tank Completely for City Driving
City driving often involves traffic congestion and frequent stops and starts. A completely full fuel tank can increase the engine's load, leading to higher fuel consumption. Given the abundance and convenience of gas stations in urban areas, there's often no need for a full tank. It's advisable to keep the fuel level below two-thirds to reduce the burden on the tank's capacity. It's worth noting that vehicles with smaller engines, which are inherently more fuel-efficient, and cars driven infrequently should carry even less fuel. With current high prices, carrying less fuel in summer can also minimize evaporative losses, serving as another fuel-saving technique. Additionally, it's important to slow down the pumping speed as the tank nears full. Pumping too quickly can prevent expanding vapor and displaced air from escaping in time, potentially causing the pump nozzle to kick back or 'spit'.
It's Best Not to Wait Until the Fuel Warning Light Comes On
When the fuel gauge warning light illuminates, it indicates the fuel level has dropped below the fuel pump's intake. Consistently waiting until this point to refuel, with the tank nearly empty or even running dry, can not only shorten the fuel pump's lifespan but also risk burning it out entirely. Furthermore, when fuel levels are critically low, the pump is more likely to draw in sediment settled at the bottom of the tank, potentially leading to pump blockage or fuel line issues. Drivers are advised to monitor their fuel gauge regularly and refuel when the indicator shows about one-quarter of a tank remaining, rather than waiting for the warning light. After all, repairs for components like the fuel pump or oxygen sensors can be quite costly.
Refuel by Volume, Not by a Monetary Amount
When at the pump, drivers can instruct the attendant to add fuel in set volume increments, such as 10 liters, 20 liters, and so on. This approach helps ensure you get the most accurate amount of fuel for your money.
With oil prices constantly fluctuating, cultivating good refueling habits is key. Avoid peak times, don't pump too aggressively, and taking good care of your vehicle is the true path to savings.
