The mistake misperception used cars

1. Tires inflated , car light , pump -inflated , brakes will eat

This is fairly common perception is off old driver told the youth committee . However actual pump wheel too tight will lose damping effects of wheel and wheel " bouncing " on the pavement reduces braking efficiency . If under-inflated wheels will destabilize in the driver that braking performance is also not increased at all. In addition, the pump wheel wrong standard settings of the manufacturer can reduce the life of the tires , dangerous in the process of using the car on the road .

 2. the increasingly wider wheel traction

Today could see the sports cars or big wheels ( 17 , 18 inches ) and thin tires , look very nice but not so efficient vehicles best traction . Traction element is generated by friction with the road tires primarily dependent on the volume of vehicles , rubber tire quality , structural chassis . So does the use of tires , contact area out back are carefully considered depending on the carmakers and tire manufacturers provide separate . Arbitrary replacement wheels to thin will lead to consequences such as shock absorbers and vehicle noise , measurement error speedometer , quick tire wear , reducing the life of the bearing detail which effectively improves traction not what significantly.

3. Vehicles used electrical devices , it is necessary battery of big

This is the normal way of thinking is very common type of "many children they have large rice cooker". However, the technical aspect, battery of only the power storage device when the car would not start when the vehicle is in operation, any responsible power supply generator cornered. With the car "as is", the manufacturer has calculated the amount of electricity used all over the car. If your personal liking for the more general use power equipment, the vehicle power shortage was solved only when replacing generators with capacity accordingly. This also explains why on the new generation car, battery size is modest, because it almost exclusively take over the function to start the engine and to stabilize voltage in the system from the pulse Noise caused by the generator.

4. ABS , EBD ... a " guardian angel "

That is true, but that is exactly the " have carefully read the user manual before use ." That is, you must understand that the ABS , EBD will support very many but not all ! The drive carefully , anticipate new situations is your guardian angel . Negligent driving , fast braking , cornering speed , inexperienced ... would be very dangerous even though the car has ABS , EBD or not.

 5. pedal some before ignition and before shutdown

Accelerator (stuffed) "cold" before the engine to pump gasoline into the carburetor and likewise before shutdown to recharge the battery. This experience is the people, "a code" apply new learner common on older cars because many "predecessors taught". However, this job is rarely effective really, because petrol pumps are electric pump supplies (while opening new power switch operation) or a mechanical pump completely not affected when the gas. In the cars used carburetors have the operation speed pump can help one of petrol is injected into the carburetor throat suction bold but sometimes more harm, the peace process could dark wet combustion chamber and spark plug, the car very difficult start. And when the vehicle is in operation, the generator will provide electricity for the battery immediately, during driving, the battery of electric considered full and charging extra for a few seconds by stuffing the station would be superfluous or rather "silly". Moreover, the kick-start and shutdown and sometimes abrupt neck suction gas balance, can do 'overwhelmed gasoline "at next boot time.

 6. What is ... viscous lubricant

If you just understand na oil lubrication effect , the risk you will not discern any lubricant used where and when it is very high . That is very dangerous . In the parking lot of the equipment for transmission oil pressure lubrication , cooling ... and each device has the appropriate lubricants such as brake fluid , engine oil , gear oil ... Themselves the oils also have the parameters and the private level , the user is very dangerous confusion or at least a damage or shorten the life car .

7. Vehicles go long will be " warm-up "

This concept car is only true for the failure of the cooling system or vehicle life too deeply, many factors affect the quality of operation of the engine. A stable motor whether rain or shine, day or night, uphill or downhill, or just truck drivers travel hundreds of kilometers ... 1km or the temperature also remained stable at an allowable level. If you change the engine temperature according to objective conditions, it means it's time to check the car overall. It was therefore no need to worry sometimes outrageous when you have to use the car to run at a low number for a relatively long distances (Pass, mountain ...) but let's focus on the driver and select the number of stars for strong and active vehicle speed.

 8. The " squeeze station " low will harm the engine rather than " pressing the "

Usually when driving at low number of floors (high rpm) sensation roars that many people worry if the engine still running high at low speeds, the engine sound does not find the liver. Therefore, many people habitually "incremental" to run high speed in any public (also known as lazy for some) because they think that doing so fewer cameras, durable and beneficial to gasoline. This is extremely wrong notion, causing serious reduce engine life. For placing large loads on the engine during low rpm (low pressure oil pump) can destroy the membrane lubrication and wear of the details slip. The high engine speed while roaring sensation but little damage to the engine in addition to fuel costs, noise and environmental pollution. Therefore, select the appropriate steps in accordance with the speed and load carrying vehicle if you want the best for your car .

9. Switch the hand in automatic car will get better slopes

In the automatic vehicle ( AT ) , use the L or the stronger one would incline to think of D is commonly found in many drive regardless of male or female . In essence , though to D or L ( 1 ) , the departure of your car with the No. 1 in the AT , drag torque at the wheels when going uphill was not changed to D or L. as our aim of manufacturers while the engineering of the control level is for the rider to actively granted the use of vehicles on specific roads such as mountain pass , crab sleeve ... when that vehicle should keep the number low to improve stability as well as take advantage of engine braking force ( engine braking ) .

10. Regularly polish to keep the new car

Have you ever wondered why your car shiny again after each polishing with chemicals ? The fact that the wax polish ( Car Wax ) in addition to the base chemical cleaning and polishing paint , there is one certain amount of abrasive grinding powder coating beaten . The car hit the ball too many times when it is not really old matt paint will make your car quickly worn, lost layers of protection and discolored . Take the car wash in the washing solution specialized vehicles , keep the ball in the paint polishing paint solvent gently . Do not let the car you dirty so long as dirt penetrates the paint loss inherent gloss .
