After S Jump-Start, Your Car Will Soon Recharge The Battery

After S Jump-Start, Your Car Will Soon Recharge The Battery

"After a jump-start, your car will soon recharge the battery. "

THIS IS NOT TRUE!

- It could take hours of driving to restore a battery's full charge, especially in the winter.

- That's because power accessories, such as heated seats, draw so much electricity that in some cars the alternator has little left over to recharge a run-down battery.

- A "load test" at a service station can determine whether the battery can still hold a charge.

A comman myth - "Synthetics cause cars to use more oil"

A comman myth - "Synthetics cause cars to use more oil"

THIS IS NOT TRUE!

- Synthetic motor oils are intended for use in mechanically sound engines, that is, engines that don't leak.

- In such engines, oil consumption will actually be reduced because of the lower volatility of synthetic lubes, better sealing characteristics between piston rings and cylinder walls. 

- And finally, because of the superior oxidation stability (i.e. resistance of synthetics against reacting with oxygen at high temperatures.)

The Battery Polarity Will Not Be Changed Once It Is Formed

A common misconception - "The battery polarity will not be changed once it is formed."

THIS IS NOT TRUE!

- You can change its polarity. 
- When it's completely unloaded, the battery is able to reverse polarity during initial charge.

Low-Profile Tires Fitted On Large-Diameter Wheels Improve Handling

A common misconception: "Low-profile tires fitted on large-diameter wheels improve handling.

THIS IS NOT TRUE!

- The short sidewalls of low-profile tires enhance the tires' response when the driver first turns the steering wheel.
- This gives the driver a false feeling that the tire has tons of grip. But after that initial movement, it's the tread compound—the stickiness of the rubber—that determines how well the tire grips the road. 
- Also, the above combination is usually heavier than the original equipment. This means the suspension may not be able to keep the tire in touch with the pavement.

Good Quality Tires Don't Get Flat Spots

Some say,"Good quality tires don't get flat spots."

THIS IS NOT TRUE!

- Though flat spots on tires are a normal occurrence for many brands and types of tires, high-performance, high speed rated (H or higher) tires are especially prone to have this problem.
- As they are engineered to maximize contact with the road surface.They are typically softer and stiffer, with a low profile and larger tread elements.
- The very qualities that make tires capable of high performance leave them vulnerable to tire flat spotting.

Will My Tire Burst If The Pressure Exceeds The "Max Press" Number

A comman misconception: A tire is in danger of bursting if pressure exceeds the "max press" number on the sidewall. 

THIS IS NOT TRUE!

- The "max press" number has nothing to do with a tire's burst pressure.
- The "max press" and "max load" numbers indicate the pressure at which the tire will carry the maximum amount of weight.
- A new, quality tire will not pop at an even multiple of the "max press". But hitting a big pothole at super-high pressures may cause a failure.
