Myth: Car start in second gear

Car transmission design emphasis on speed. If it reluctant to use second gear start will not only increase the load on the engine, clutch and can lead to early wear and tear, so the car no matter how much emissions should start a file.

Myth: High-grade bit more fuel-efficient small throttle

Possible, the best section of this approach prone to engine knock, the fuel power of the outbreak can not completely work, and the impact of linkage, resulting in early wear and tear, the lack of torque at low rpm, accelerating weakness, but fuel consumption will be increased oil protected mode but the engine is working in the low region of the maximum torque speed may get the maximum power and the best fuel efficiency.

Myth: the car starts warm-up 10 minutes

Preheating before the car starts, the mechanical member can be better lubrication and reduce friction and prolong life. However, not too long warm-up time, the lubricating oil can reach the desired lubrication can be generally recommended 5-8 seconds. For too long, it will only result in fuel consumption and engine wear large. Automatic transmission car, so the car from starting when the speed dropped to 800 rpm or so more appropriate, of course veteran could tell from the sound.

Myth: anti-wear agents extend the oil life

Better anti-wear agent anti-wear properties, oxidation resistance myself are weak, but the more the amount of oil the greater the damage.

Myth: upshift overtaking

Motorists generally considered high-end bit faster, so the way to overtaking the rise of a file. Indeed forward vehicle must be played by the engine torque, high gear torque small, slow throttle response, acceleration but slow down, so the correct overtaking should slow down a gear, automatic transmission only throttle in the end, the transmission will a gear reduction to provide sufficient torque.

Myth: After the first step on the clutch brake

Some people think we should cut off the power before the brakes, the brakes will be more effective, it is a serious mistake. Because depressed the clutch, the engine idling speed rapidly decreases, reducing the combined total intake pipe vacuum, greatly reduce the assist force of the vacuum booster, the braking distance, but longer. Correct operation, should the brakes, when the vehicle speed is reduced to close to stop again depresses the clutch.

Seven Mistakes: while cornering brake

When the center of gravity toward the outside of the car turn, then roll the brakes will increase, resulting in unilateral braking, if too fast or brake too fast, there is the risk of rollover. The right approach should reduce speed before entering the curve change into low gear after into the corners, slow refueling the body in order to maintain stable posture.

Myth Eight: backhand hit the steering wheel

Older car, the steering wheel is heavier, more effort backhand hit the steering wheel, while the new car this operation more dangerous when playing backhand direction, if the wheels rolling obstacle suddenly rebound, the wrist would be seriously hurt, so to develop good diet (typically the left hand placed 9 or 10 o'clock position, corresponding to the right hand put 3 or 2-position, a hand push, on the other hand the relay pull-down manner turning the steering wheel), not cross-hand backhand hit the steering wheel.

Myth 9: Coasting downhill

Some car owners in the downhill, for the convenience of drawing, hang gliding in neutral, only the brakes to control speed, this is certainly presence of potentially hazardous, if it is in a long-distance slope position to do so, the system will brake suddenly failed due to overheating, lead to accidents. The correct approach is to put the proper gear for the actual vehicle speed, so that engine braking, brake occasionally supplemented, so that safe and extend brake life.

Ten Mistakes: the slower the speed the better the run-in period

Run-in period is a period of time to the friction member with the gap mill to a reasonable range, in order to achieve a better lubrication. If the running of the engine speed is too low, the crankshaft rod bearing to withstand greater impact, the speed is too high cylinder wall is easy to strain, resulting in early wear and tear, it should be run-in period with reference to a vehicle speed rather than engine speed, the gasoline engine speed 2000- between 3000 rpm, the diesel engine between 1000-2000 rpm.

Mistakes XI: neutral may put fuel-efficient

Carburetor fuel-efficient car is put in neutral, but not necessarily EFI car fuel, because fuel cut some cars off the accelerator, fuel injection system during acceleration, rpm restore fuel supply when engine speed to 2000, so EFI will be fuel-efficient cars with high-speed gear when coasting, but cost of oil put in neutral.
