Tip 1: Try to fix the refueling point
Example review: A few days ago, Xiao Dai's car went into the repair shop because it could not start. After inspection, the maintenance technician told him that there was a problem with the oil quality, which caused excessive carbon deposits on the fuel injection nozzle, causing blockage. Since Xiao Dai did not have a fixed refueling point and was not used to issuing invoices, he could no longer verify which gas station had a problem with the oil.
Maintenance technicians remind: When refueling your car, you must fix the refueling point. Try to choose gas stations from China National Petroleum Corporation and PetroChina, as the oil quality is guaranteed. Remember to issue an invoice after refueling as proof.
Tip 2: Do not change the gasoline label at will
Case review: Mr. Wang's car broke down. It had difficulty starting, unstable idling, and poor acceleration. The inspection found that there were carbon deposits on the engine valves, combustion chambers and intake pipes. After being questioned by the maintenance staff, Mr. Wang told the truth: In order to save money on gas, he changed the original No. 97 gasoline to No. 93 without authorization.
The commonly referred to as No. 90, No. 93, and No. 97 are gasoline labels, which represent the ratio of actual gasoline anti-knock properties to standard gasoline anti-knock properties. Experienced drivers all know that if a high-compression ratio engine uses low-grade gasoline, it will cause knocking, accelerate the aging of parts, and easily cause failure. Therefore, car owners should choose different grades of gasoline according to the different engine compression ratios.
The gasoline number will be found in every vehicle's owner's manual. For example, mid-range cars with a compression ratio between 8.5 and 9.5 should use No. 93 gasoline; cars with a compression ratio greater than 9.5 should use No. 98 gasoline. Car maintenance experts believe that saving money by lowering the gasoline grade will only do more harm than good. But it is not that the higher the grade of gasoline, the better. If you are required to use low-grade oil, you must use high-grade oil. Not only will it not improve efficiency and power, it will also damage the engine.
Tip 3: Only add half a tank of oil when it’s hot
Case review: When netizen 'vixi' fills up his car with gas, he can often smell a strong smell of gasoline. After consulting a car maintenance expert, I learned that when the weather is hot, overfilling with gasoline is not only easy to evaporate and emit odor, but also causes the gas outlet of the fuel tank to be immersed in gasoline, and the gas outlet pipe will flow into the carbon canister.
Car maintenance experts believe that when the weather is hot, the capacity of gasoline in the fuel tank is about half to two-thirds. Filling up the tank will increase the load on the engine, and driving in urban areas with frequent stops will consume more fuel. You can't wait until the oil is completely dry before adding it again. When the fuel gauge needle is close to or just pointing to the red line, it's time to consider refueling.
Tip 4: Fuel up in the morning and evening to save money
Example review: Ms. Zhang is a careful person and usually carefully observes the fuel consumption of the car. Through comparison, she found that if you add the same amount of oil in the morning, you will drive at least 20 to 30 kilometers more than if you add it in the middle of the day.
The reporter asked the staff of PetroChina and the answer was: it is indeed more cost-effective to refuel at night or early in the morning. Because gasoline is priced by volume rather than weight, according to the principle of thermal expansion and contraction, the volume of gasoline is smaller at night and early in the morning when the temperature is lower, so you can add more fuel for the same money.
Another point to note is: Try to avoid the period when the gas station is refueling the oil storage tank. At this time, the sediment at the bottom of the oil storage tank is stirred up. If you wait in line to refuel, it is inevitable that impurities will be added to the gasoline, which will increase carbon deposits in the engine.
Tip 5: Fill up your tank before running a long distance
Example review: Netizen 'Diesel Engine''s favorite car is a BMW 745, and he usually 'drinks' 98-proof gasoline. Once, a car club organized a rural tour, and the 'diesel engine' who happily went there forgot to reserve more 'food' for his car. He couldn't find 98-proof oil along the way, which delayed everyone's journey.
Before running a long distance, the more fresh oil, the more powerful the acceleration will be when driving at high speed. Before setting off on the highway, you should fill up your tank with gas. Cars that use high-grade oil need to prepare some additional gasoline additives. The additives can increase the grade of the oil by 1-2 numbers. If the fuel labels at gas stations along the way are insufficient, you can make up for it appropriately.
