The same car, the same road conditions, some people drive 8 liters of fuel consumption, some people drive 12 liters of fuel consumption, this is the difference between the old driver and the novice in the details, the car wants to save fuel and have fewer failures, these 40 points of experience are worth seeing.
Practice the "golden right foot" driving method.
1. When starting, don't step on the accelerator with a big foot, there is too much fuel consumption wasted at the start, look at the instantaneous fuel consumption, which is almost 3-10 times that of normal driving.
2. On the way to drive, according to the road conditions, make a good prediction in advance, for example, there is a red light intersection in front, and there is only 1-2 seconds left in the green light, judge that it cannot pass, according to the distance, release the accelerator in the appropriate position, and let the vehicle idle + inertia to the intersection.
3. Some novices may not grasp this "degree" well, and loosen the throttle in advance, resulting in a quick stop before the intersection, and then refuel at this time, which naturally costs fuel, and some may misjudge the mistake, and only release the throttle when they reach the intersection, and can only brake deeply to brake.
4. When encountering an uphill section, accelerate in advance, use the inertia of the vehicle to buffer, do not wait until the uphill is close to increase the throttle, see that you are about to reach the top of the slope, release the throttle in advance, and also use inertia, so that you don't need to step on the brakes immediately to slow down when going downhill.
5. Flat road driving, often "stepping on a loose" does not necessarily save fuel, for example: the speed of 120 km / h, some people will release the throttle, let the vehicle drive by inertia, and wait for the speed to drop to 100 km / h, and then step on the accelerator to accelerate, and the cycle repeats this operation, thinking that it can save fuel, but in fact, it is not.
The speed of 120, at this time let go of the throttle, the use of inertia driving, can indeed save fuel, but when the speed drops to about 110, it can not continue to drop, at this time it is necessary to continue to step on the throttle, down to 100 and then step on the throttle and down to 110 on the throttle, the fuel consumption of the former is almost more than twice that of the latter.
The relationship between speed and fuel economy should be grasped!
6. Generally speaking, small displacement models, the vehicle runs at a constant speed of 55-65 per hour, which is relatively fuel-efficient, and for large displacement models, especially turbocharged models, the speed is relatively more fuel-efficient in the range of 65-75.
7. On the highway, if you only talk about fuel saving, the speed is relatively fuel-efficient in the range of 90-100, but the premise is according to the road conditions, of course, you can't drive at a speed of 90-100 in the fast lane in order to save fuel, which is not safe and not recommended.
In everyday driving, these details need to be remembered.
8. Keep an appropriate safety distance from the car in front, not too close, so that you can use the inertia of the vehicle to brake more and reduce the frequency of braking, but not too far away, so that someone will always plug in, but you can't avoid stepping on the brake.
9. After the vehicle starts, do not idle the car for a long time, the current car is not the carburetor era, the EFI technology does not need to be specially heated up, after the ignition starts, wait a few seconds, wait for the vehicle speed to drop, the engine sound is stable, and the normal start can be.
10. Reduce the burden on the vehicle, often use the car around the city, the tool kit, mineral water, inflator pump, jack, and even the spare tire in the trunk can be removed to reduce the weight of the vehicle, every 100 kg reduced, the average fuel consumption of the vehicle per 100 kilometers can be saved by almost 0.3-0.6 liters.
Daily maintenance is closely related to fuel consumption.
11. Maintain on time and according to quality, according to the maintenance manual, do not use mineral or semi-synthetic engine oil if you can use fully synthetic engine oil, and replace the oil and filter every 8000-12,000 kilometers or once a year.
12. According to the requirements of the model and maintenance manual, replace the air filter and fuel filter in a timely manner every 2-30,000 kilometers or every 2 years.
13. Replace the transmission oil in a timely manner, or according to the model, such as AT gearbox, generally 5-70,000 kilometers to replace once, try not to exceed too much, although some cars have not changed the transmission oil for 100,000 kilometers, and it looks fine, but in fact, the failure of the car is slow, and it is okay to look at it in a short time, when the small problems accumulate to the big problems, it is too late to regret.
14. The tire pressure of the car should be adjusted well. The tire pressure is too low, the tire ground contact area increases, the friction increases, and the fuel consumption will also increase, of course, the tire pressure is not as high as possible, the tire pressure is too high, the tire wear will increase, and the ride comfort is not good, and the bumpy feeling is obvious.
15. Four-wheel alignment, if you run at high speed, you find that the direction is easy to deviate, and the swing amplitude is larger than usual, you can go to the 4S shop and maintenance shop to see and adjust.
16. Check the brake fluid regularly, the general brake oil can be used for 2-4 years or 3-60,000 kilometers, specifically according to the moisture content of the brake fluid to judge, the moisture content is higher than 3%, remember to replace it as soon as possible.
17. Check the antifreeze coolant regularly, if the coolant is too low, it will affect the cooling effect of the engine, and then affect the working efficiency of the engine, and the fuel consumption will also be affected.
18. According to the requirements of the model and maintenance manual, replace the spark plug in a timely manner, especially when the vehicle mileage exceeds 100,000 kilometers or 6 years later, if necessary, you can replace the better spark plug in advance.
19. If the vehicle is more than 8 years old or more than 120,000 kilometers, you can check the fuel tank carbon canister, solenoid valve, oxygen sensor, throttle and other parts, and clean or replace them in a timely manner, which is more conducive to fuel saving.
20. After the mileage exceeds 8-100,000 kilometers, remember to check the carbon deposit of the engine, and clean up the carbon deposit in advance when necessary.
Come on, pay attention!
21, designated to add 92 and above the number of gasoline models, try to add 95 gasoline, you don't see 95 gasoline than 92 gasoline is more expensive than 92 0.5 yuan / liter, in fact, now most of the models are intelligent adjustment of the ignition advance angle, 95 gasoline anti-knock performance is better than 92.
Usually in the urban area may not be obvious, but on the high speed, the engine condition is better, at the same time 95 gasoline reduces the detonation, improve the engine work efficiency, at this time, add 95 gasoline, the mileage will be slightly more than the mileage of 92 gasoline.
22. Try not to go to some private small workshops and gas stations to add cheap oil, if the oil is not good, not only the fuel consumption will increase, but also the vehicle will have a greater impact.
23. In general, pure gasoline is more durable than ethanol gasoline, and it is better to choose pure gasoline if you can add pure gasoline.
24. Every time you refuel, fill up and add half, in fact, you are particular about filling too full, which will not only increase the weight of the vehicle, but also may affect the fuel tank carbon canister, and then increase fuel consumption, so if you usually use the car in the urban area, it is enough to keep the vehicle with about half of the oil.
25. If you don't use the car for a long time, the gasoline in the fuel tank will continue to volatilize and the oil will also be affected, after all, the gasoline also has a shelf life, and it is not necessary to add too much oil to the tank when it is parked for a long time.
26. Specify the car with No. 95 gasoline, do not add No. 92 gasoline, occasionally add the wrong one, it may not have much impact, but after a long time, the problem will naturally come out.
Other fuel-efficient options.
27. Small-displacement models are more fuel-efficient than large-displacement models, and naturally aspirated models are more fuel-efficient than turbocharging. In general, Japanese cars are more fuel-efficient than German cars.
28. The lighter the weight of the vehicle, the more fuel-efficient, the general SUV vehicle is heavier, the wind resistance is larger, and the fuel consumption is higher than that of the same level car.
29. Narrow tires are more fuel-efficient than wide tires, and the larger the area in contact with the road surface, the greater the friction, and the higher the fuel consumption.
30. It costs oil to open the cold air conditioner in summer, but the heating air conditioner in winter will not significantly increase fuel consumption, mainly because the cold air conditioner is compressed in summer, and the warm air conditioner in winter is to use the high temperature of the engine to become a warm air conditioner after conversion, at most it is to increase the power, and the fuel consumption is slightly more, which can be ignored.
31. When driving, when the speed exceeds 40 km/h, the wind resistance is large, do not open the window, especially when the window is completely opened than the air conditioner is more fuel-efficient.
32. When the vehicle is moving, the speed of the wiper should be moderate, and there is no need to be fast when it is not too fast, and the faster the wind resistance, the greater the wind resistance.
33. Cars without sunroofs and roof racks are more fuel-efficient, and it is still a problem of wind resistance.
34. Open automatic transmission models, do not drive in D gear all the time, according to the type of vehicle gearbox, for example, AT manual automatic transmission, encounter many curves, large slopes, need to overtake, full load and other scenarios, try to use manual mode, manual mode can adjust the gear and throttle in time according to the actual road conditions, which is more fuel-efficient.
35. Generally speaking, small displacement models will be more fuel-efficient on national highways, provided that the road conditions are good, and medium and large displacement models are more fuel-efficient at high speeds, of course, they need to add tolls.
36. The closed chassis is more fuel-efficient than the open chassis, and the lower part of the chassis is conducive to reducing wind resistance, which is naturally more fuel-efficient. Similarly, the vehicle has fenders and door rain gutters, which will increase wind resistance and consume fuel.
37. Wearing thick shoes may be more fuel-intensive than flat shoes, with thick soles, and the foot feeling may not be so good, which will affect the performance.
38. Before traveling, plan the route in advance, the same section of the road, the more traffic lights mean that the more uncertain congestion time may be, even if it is a familiar route, try to open the navigation, you can grasp the road conditions at any time, avoid congestion, and reduce fuel consumption.
39. When running at high speed, cruise at a fixed speed is not necessarily fuel-efficient, driving at a fixed speed on a flat road is indeed fuel-efficient, but it costs fuel in road conditions such as climbing and curves.
40. Reasonable use of automatic start and stop function, generally speaking, waiting for the red light for more than 20 seconds can be enabled, but if it is only a few seconds, there is no need to turn on the automatic start and stop, frequent start not only affects the life of the battery but also increases fuel consumption.
