So read on to find out the truth behind some common auto myths.
1. You need to warm your car before starting out in cold weather: FALSE.
Idling isn't an effective way to warm up your car in the winter -- driving away is. Today's engine and fluid technology is designed to start working as soon as you turn the key (or at lease once your windshield is defrosted). Not only does idling waste gas and cause pollution, it can actually cause damage to your vehicle.
If you're faced with severe winter conditions, you may want to consider a block heater, which warms the engine, or a battery warmer. A battery loses power as the temperature goes down, so warming it gives it that extra boost.
2. All-season tires are as good as winter tires: FALSE.
In the old days, winter tires were knobby things with coarse textured treads. You'd put them on the back two wheels of your rear-wheel-drive car and they would help get you started. Today's high-tech snow tires offer greater control, stability and braking capabilities, so putting winter tires on all four wheels gives you more control when starting, stopping and taking corners.
"Winter tires for ice and snow performance are far superior than all-seasons," says Ralph Warner, director of operations of the Rubber Association of Canada. "With the new rubber technologies and compounds, winter tire compounds have a much better gripping capability in colder temperatures."
3. Restarting your engine is harder on the engine and uses more fuel than idling: FALSE.
Starting and stopping your engine has little impact on the starter motor or battery of today's vehicles. "Today's cars have pretty strong starters and good electrical systems," says Armour. "We need to think of gas mileage and the environment."
According to Natural Resources Canada, or NRC, component wear caused by restarting is estimated to add $10 per year to the cost of driving -- far less than what sitting still costs you in gas. In fact, the NRC recommends that if you're going to be stopped for 10 seconds or longer (except in traffic), it's best to turn your car off. Ten seconds of idling can use more fuel than turning off the engine and restarting it.
4. Filling your tires with nitrogen is better than using plain air: MAYBE.
Some studies have shown that filling your tires with nitrogen reduces gas consumption and improves tire life by maintaining an even tire pressure. Nitrogen molecules are larger than oxygen molecules so they don't leak through the tire walls as readily. Underinflated tires wear out faster, cost more money in gas and are a safety hazard.
But this added convenience will cost you between $5 and $10 to have each tire filled with nitrogen. Not every service station offers nitrogen and topping up with air negates the benefits.
So unless you're a racecar driver, you might want to stick to old-fashioned air. "I think it's one of those unnecessary things," says Kerr. "Spend your money on it if you really want to keep your tire pressure accurate. You're better off buying a good gauge."
Use that gauge to check your tire pressure once a month and keep tires filled according to the optimum pressure (not the maximum, which is the number found on the sidewall of the tire).
Treating your car right
To keep your car in tip-top shape, go to the real experts. "Talk to your service manager at the dealership or a good mechanic at a garage," says Kerr. Don't be afraid to ask questions as to what you should be doing or doing differently.
Ask them, "If it was your mother's car, what would you really have to do to make it safe to drive?" And keep the pantyhose in the lingerie drawer.

"Moreover, you scorned our people, and compared the Albanese to sheep, and according to your custom think of us with insults. Nor have you shown yourself to have any knowledge of my race. Our elders were Epirotes, where this Pirro came from, whose force could scarcely support the Romans. This Pirro, who Taranto and many other places of Italy held back with armies. I do not have to speak for the Epiroti. They are very much stronger men than your Tarantini, a species of wet men who are born only to fish. If you want to say that Albania is part of Macedonia I would concede that a lot more of our ancestors were nobles who went as far as India under Alexander the Great and defeated all those peoples with incredible difficulty. From those men come these who you called sheep. But the nature of things is not changed. Why do your men run away in the faces of sheep?"
Letter from Skanderbeg to the Prince of Taranto ▬ Skanderbeg, October 31 1460
