5 BS Facts About Driving that Everyone Thinks are True

By Edited Mar 30, 2016 0 0

The majority of people nowadays in Western countries drive everywhere. You drive to work, school, shopping. But do you really know your facts from the lies when it comes to getting in your car? Here are a few myths that everyone's heard, and an awful lot of people believe...

1.     Overfilling...

For driver's in the north, where weather conditions can get pretty snowy and icy, rhis is a fairly commonly believed myth. The story goes that by overfilling your tires with air (i.e. putting more air into the tires than manufacturers recommend) you get better traction on slippery surfaces. This simply isn't true. Think about it. Sure, if your tires don't have enough air it's pretty dangerous, tehy won't be able to grip the surface of the road and you'll skid. But filling tires up too much means that the tire expands until only the very centre of the tire is touching the road. That can't possibly be good for traction. The manufacturer's recommendation is based on strict research, and you should never fill your tires more than four to five points over the recommended PSI level.

2.     Premium is better...

Premium petrol is more expensive, so it must be better, right? Not necessarily. This is a fairly modern myth. In the past, it was true that premium gas made your car run better. In fact, in older cars if you used cheaper gas you often heard knocking noises coming from the engine, as the gas exploded before the spark plug fired. However, modern cars come with knock sensors that make the car's engine adjust its timing to stop this happening. It's no longer necessary to buy the expensive stuff, just regular fuel is fine for the majority of cars.

3.     Sandbagging...

Ever get told that you need to fill your boot with sandbags to get better traction in the snow? This myth has been around forever. Truthfully, back in the sixties and seventies this was true. Weighing down the back of your car did help give you better traction on slippery surfaces. However, the design of cars has changed a lot in the last forty years or so. Modern cars are nearly all front wheel drive. Putting sandbags in the boot of a front wheel drive car will do nothing except give you a heavy boot, and possibly leave you with a lot of sand to clean up. Don't bother. In fact it will take weight OFF your front wheels, giving them less grip and making your steering very light.

4.     Oil Changes...

This myth probably has a lot to do with advertising. Plenty of service stations even nowadays advertise that you should get your oil changed every 3,000 miles. But given the advances in both engine design and oil refinement this is simply no longer true. Modern cars generally need an oil change about every 7,500 miles, and some synthetic oils claim that you can go 15,000 miles before a change. Of course, the service stations want to make money, so they continue to advertise the 3,000 mile rule. You should check the manufacturer's instructions for your car model to find out how long it should really be though.

5.     Idling...

So, instead of turning your engine off, do you let it idle while you're waiting? There's some debate about whether people do this to try to save fuel, or they just think it's damaging to turn the engine on and off too much. The truth is though, that you shouldn't be idling. Turning the engine off is better for fuel economy, and is just generally safer. There's less chance of accidental movement or fire when the engine is off. Don't bother letting it idle, you're not accomplishing anything.
