As of 24:00 on July 31, domestic refined oil prices are set for an adjustment. After completing 50% of the 10-working-day statistical cycle, and influenced by a sharp increase in international oil prices today, the current crude oil change rate has reached 14.64%. This translates to an expected price increase of 780 yuan per ton. Based on current projections, gasoline and diesel prices will see another significant jump next week, estimated at 0.59 yuan to 0.70 yuan per liter.
Oil price fluctuations concern many drivers, making the accuracy of fuel dispensers a top worry. "The city's 480-plus gas stations, with over 7,500 fuel nozzles, undergo mandatory inspection every six months, achieving a 100% coverage rate. All inspected nozzles meet metering standards," said Hu Peng, Director of the Livelihood Metrology Department at the Wuhan Institute of Metrology, Standardization, and Quality, offering reassuring data. Peng Hui, Director of the Quality, Health, Safety, and Environment Department at Sinopec's Wuhan branch, stated on-site that the company strictly controls quality and measurement from the source, implementing dedicated vehicle transport and full GPS dynamic monitoring. Oil samples must pass testing before sale, complemented by monthly self-checks, quarterly quality audits, and semi-annual mandatory inspections to comprehensively uphold measurement standards.
What should consumers watch for when refueling? Hu Peng offered on-site advice: First, check the location and choose a compliant gas station. Second, look for identification—ensure the dispenser displays a valid inspection certification mark. Third, verify resetting—confirm the dispenser shows "zero" before fueling. Finally, check if the amount and volume match. If there are any measurement concerns, consumers can call the 12315 hotline to file a complaint.
"Why does the dashboard's estimated range not match actual driving distance?" Addressing this common confusion, Hu Peng explained that the range is calculated by the car's computer based on average fuel consumption and remaining fuel. Average fuel consumption changes with driving conditions, and there are minor deviations in the remaining fuel calculation, so the range should only be used as a reference. Additionally, factors like fuel price fluctuations, driving habits, and road condition differences all contribute to discrepancies between actual mileage and expectations.
Six Fuel-Saving Tips to Keep in Mind
Driving Habits: The Core Switch for Fuel Economy
Harsh acceleration and frequent hard braking can instantly spike fuel consumption by up to 30%! When starting, accelerate gently to allow the engine speed to rise smoothly, avoiding high-load operation. While driving, maintain a steady speed—around 60-80 km/h on city roads and no more than 120 km/h on highways (most vehicles achieve optimal fuel economy in this speed range). When approaching a red light or traffic jam, release the accelerator early to coast instead of braking hard at the last moment. This not only reduces brake wear but also saves a significant amount of fuel.
Reduce Vehicle Weight: Don't Let Your Car Carry Extra Load
Long-term clutter in the trunk, roof racks, and external trunk storage boxes all increase wind resistance and vehicle weight. According to tests, every 100 kilograms of added weight can increase fuel consumption by 5% to 8%. Regularly clean out unnecessary items from the trunk and remove unused external accessories to help your car "travel light" and naturally lower fuel consumption.
Air Conditioning Use: Choosing the Right Mode Saves More Than Not Using It
Many think using the AC consumes fuel, but blindly opening windows can be worse! At speeds below 60 km/h, opening windows for ventilation is more fuel-efficient than using the AC. However, at speeds over 80 km/h, the wind resistance from open windows consumes more fuel than the AC compressor's energy. Also, when using AC, open the windows for two minutes to expel hot air before closing them and cooling. Set the temperature between 24-26°C and use the recirculation mode to reduce the load on the AC system and further save fuel.
Regular Maintenance: Keep the Engine Working Efficiently
The engine is the heart of the vehicle, and poor maintenance directly increases fuel consumption. Change the oil on time (using the manufacturer's recommended grade), as oil that is too thick increases engine resistance. Regularly clean the air filter, as a clogged filter causes insufficient air intake and incomplete combustion. Check tire pressure, as under-inflated tires increase contact area and rolling resistance. For every 0.3 bar drop in pressure, fuel consumption can rise by 1%.
Route Planning: Avoiding Traffic Jams Saves Fuel
Idling in traffic jams only increases fuel consumption! Use navigation apps to check real-time traffic before heading out, avoiding congested routes and peak hours. Choose routes with fewer traffic lights and smoother roads to reduce frequent stop-and-go driving. On the same distance, a clear route can save over 20% in fuel compared to a congested one, while also saving travel time.
Small Habits: These Details Also Save Fuel
Turn off the engine when idling for extended periods (over 3 minutes), such as at long red lights or while waiting. Refueling in the morning or evening can be more economical due to thermal expansion, where cooler temperatures make fuel denser, providing more mass for the same volume. Don't always fill the tank to the brim; for short city trips, consider filling half a tank to reduce weight, and only fill up fully for long journeys to avoid extra trips to the station. Reduce aggressive overtaking, as the high RPMs during such maneuvers cause a sudden spike in fuel consumption; avoid unnecessary lane changes and overtaking.
