10 most frequently asked car maintenance questions

1- How often should I change my oil?

The standard frequency is every 6 months or 10,000 km. But it really depends on how you use your vehicle. Extended idling (especially in winter), dusty roads, and city traffic are all factors. Most late-model vehicles have an oil change indicator. Otherwise the information is provided in the owner’s manual. It’s still a good idea to check your oil every time or every second time you fill up on gas. Running out of oil can be disastrous for your vehicle’s engine and cause costly repairs. As for the filter, it’s an integral part of the system and should be replaced when you change the oil.

2- Should I fold up my wipers if there’s freezing rain?

No. Whenever freezing rain is in the forecast, you always see drivers folding up their wipers so they don’t get stuck in the ice. That might seem like a good idea, but it actually puts tension on the wiper arm, which can cause premature wear and tear and reduce performance in the long run. Keeping your wipers in the vertical position also leaves them exposed to the elements, which could cause damage. Plus strong winds could send the wipers crashing down onto windshield and cause cracks. Check out our tips on defrosting your windshield in question 8!

3- When should I change my winter tires?

It depends. In Quebec, winter tires are mandatory from December 1 to March 15. But the weather varies from one region to another, so you can’t just rely on the required dates. CAA-Quebec recommends putting your winter tires on as soon as the temperature gets down to around 7°C for a few consecutive days. It’s a good idea to book an appointment at your garage as early as the end of September. That way you’ll be sure to have your winter tires on in time for the first snowfall.

4- Which tires should I buy?

There are a number of factors to consider when choosing winter tires, including price, tire construction, and how you use your car. Check out all the questions you need to ask in our Quick guide to buying winter tires. A trusted mechanic can also answer your questions, as can CAA-Quebec Automotive Advisory Services.

Please note that CAA-Quebec does not recommend all-weather tires for winter driving and advises you to do your homework before buying tires manufactured in China or purchasing tires online, since quality can vary.

5- What’s the correct tire pressure?

The correct tire pressure varies from one car to another. It depends on the vehicle’s weight and a number of other factors. To find out the recommended tire pressure for your vehicle, check the sticker that’s usually found on either the door frame, in the glove box, or inside the fuel cap or check your owner’s manual. Check your tire pressure every month, especially in winter. Tires automatically lose 1 PSI for every 6°C drop in temperature, so if it was 10°C out when your winter tires were installed in October, they’ll have lost 5 PSI by the time the mercury drops to a frosty −20°C!

6- What should I do when the check engine light goes on?

The check engine light can indicate lots of different things, from trivial issues to big problems.

- If the light comes on, you can still drive all the way home! The first thing to do is remove your gas cap and put it back on, making sure to turn it until you hear a click. That often solves the problem. If not book an appointment at your garage It could be an emission control system malfunction that will affect your gas mileage and the environment.

- If the light starts flashing, stop and have your vehicle towed to your local garage. A flashing light indicates a serious problem that can cause considerable damage your car (e.g., faulty ignition coil) and jeopardize your safety.

Driving electric? It’s still important to get any warning lights checked out by a trustworthy, qualified mechanic.

7- Should I rustproof my car every year?

Rustproofing is one possible solution for protecting your car’s body and chassis, but it’s not your only option. The idea is to combine several measures, remain vigilant, and quickly repair any scratches before rust sets in. For example, it’s a good idea to take advantage of a winter thaw to wash your vehicle and remove any built-up salt and calcium. Don’t despair if rust does appear. There are solutions not only for preventing rust, but also for stopping it in its tracks.

8- How do I defrost my windshield?

- For the outside of the windshield, use a good quality scraper (available at garages, department stores, and the CAA-Quebec Boutique) that’s suitable for your vehicle (e.g., with a telescopic handle if you have an SUV or pickup). If there’s ice, use the side with spikes to break and remove it, but don’t go too hard, especially near the mouldings. It’s also a good idea to use a windshield washer fluid rated to −35°C.

- You can also use a scraper for the inside of the windshield, but remember that you’ll have less frost if you keep your windshield and other windows clean and reduce the humidity inside your car. That includes knocking the snow off your boots before getting in.

Of course it’s always important to properly clear the snow from your entire vehicle for your own comfort and safety and the safety of other motorists.

9- What should I do if my car is subject to a recall?

If the dealer or automaker has your contact information, they’ll notify you if your car is subject to a recall. If not, you need to keep an eye on Transport Canada’s Motor Vehicle Safety Recalls Database Then make an appointment at your dealership to have the necessary repairs or changes made free of charge. As a consumer, you are responsible for staying informed about recalls affecting your vehicle.

10- Is it a good idea to forego damage insurance?

In Quebec, vehicle owners are required to carry at least $50,000 in third-party liability insurance to cover at-fault damage caused to others. Opting for third-party liability coverage only without insuring your own vehicle for damage is most suitable if your vehicle is worth less than $5,000 and was paid in full at purchase. Lenders require damage coverage if the vehicle is being used as collateral. Keep in mind also that a vehicle with the minimum amount of coverage can’t be used outside Quebec, since some provinces have higher minimum third-party liability requirements (e.g., $200,000 in Ontario). Another disadvantage is the fact that you’ll risk having to pay for damage to your vehicle in the event of theft, fire, vandalism, or an accident.

For your own peace of mind, it’s better to have comprehensive insurance. Talk to your insurer to get coverage that fits your situation and budget. Remember also that proper vehicle maintenance is key to avoiding problems and keeping your vehicle on the road for the long haul. A full or partial inspection of your car is also a good idea, and not only if you’re looking to sell.
