What are the essential car maintenance tasks every owner should do?

Jun 2, 2025

Vehicle maintenance is critical for Canadian drivers. From sub-zero winters to sweltering summers, cars are subject to constant environmental stress. Road salt, potholes, and wide temperature swings can all affect performance and safety. Routine upkeep helps prevent mechanical issues, improves reliability, and ensures optimal fuel efficiency. In addition to preserving the vehicle’s condition, proper maintenance can also influence insurance coverages auto policies, as insurers may view well-maintained vehicles as lower risk. Staying ahead of maintenance needs may even help drivers avoid claim denials due to neglect. Here, we outline the key maintenance tasks every Canadian car owner should prioritize throughout the year to keep their vehicle in peak condition:

 

Change your engine oil regularly to protect the heart of your vehicle

Engine oil lubricates and cools the engine's moving parts. It reduces friction and protects against wear. Over time, the oil becomes contaminated with debris and combustion by-products. This contamination lowers its effectiveness. Regular oil changes preserve engine health and efficiency. Most vehicles need an oil change every 5,000 to 8,000 kilometres, though specific intervals depend on the make, model, and driving habits. Always refer to the owner’s manual for guidance. In Canada, where winter temperatures drop well below freezing, synthetic oil works better than conventional options. It flows more reliably in cold conditions, helping the engine start with less strain. Skipped oil changes can cause sludge buildup, degrade performance, and lead to expensive engine repairs.

Inspect and replace air filters to support engine performance and fuel efficiency

Air filters trap dust, dirt, and other particles before they enter the engine. A clean air filter ensures steady airflow, better combustion, and lower emissions. A clogged or dirty filter restricts airflow. This restriction can reduce engine power, increase fuel consumption, and lead to engine wear. If you frequently drive on unpaved roads, in construction zones, or through urban smog, replace the filter more often. Check the cabin air filter as well, as it affects the vehicle’s ventilation system and in-cabin air quality.

Monitor tire pressure and condition to ensure safety and performance

Temperature swings affect tire pressure. In cold weather, pressure drops and can fall below safe levels. In summer, pressure rises and can exceed the manufacturer’s recommendations. Both conditions create safety and performance concerns. Underinflated tires cause uneven tread wear, reduce fuel efficiency, and increase the risk of blowouts. Overinflated tires reduce traction and make the ride harsher. Check tire pressure once a month and before every long trip. Use a reliable pressure gauge for accuracy. Rotate your tires every 10,000 kilometres to promote even wear. Inspect tread depth regularly. Replace tires when the tread depth falls below 1.6 mm or when cracks, bulges, or other signs of damage appear.

Test and maintain the battery to avoid cold-weather failures

Battery performance drops significantly in freezing temperatures. A weak battery may fail without warning in cold weather. Test the battery each fall before winter sets in. Most auto shops can perform a quick test to measure battery strength. Clean any corrosion from the terminals and tighten all cable connections. Corroded or loose terminals disrupt current flow. Replace the battery every 3 to 5 years, depending on climate, vehicle use, and battery quality. If you notice slower engine cranking or dimming lights, test the battery promptly.

Check and top up fluids to prevent component failure

Vehicles rely on several fluids for function and longevity. These include engine coolant, brake fluid, transmission fluid, power steering fluid, and windshield washer fluid. Each fluid plays a unique role. Coolant regulates engine temperature. Brake fluid ensures responsive braking. Transmission and power steering fluids support smooth gear shifts and steering control. Use only the fluid types specified in your owner’s manual. Check levels monthly and look for leaks. Flush or replace fluids at the intervals recommended by your vehicle’s manufacturer.

Replace windshield wipers as needed to maintain clear visibility

Effective wiper blades ensure clear vision in rain, snow, and slush. Wipers degrade over time due to sun exposure, dirt, and temperature fluctuations. Old or damaged blades can leave streaks or fail to clear the windshield properly. Inspect blades every few months. Replace them at least once per year. For harsh winters, install winter-rated blades with durable rubber and protective frames. These resist ice buildup and perform better in snow and freezing rain.

Inspect brakes regularly to ensure stopping power

Brakes must respond reliably in all weather conditions. Moisture and salt from winter roads accelerate corrosion on brake components. Brake pads wear down through use, while rotors and calipers suffer from exposure and stress. Listen for squealing, grinding, or vibration during braking. These signs indicate worn or damaged parts. Schedule a brake inspection at least once a year or any time performance feels compromised. Have a mechanic check pad thickness, rotor condition, brake fluid level, and hose integrity

Pay attention to warning lights to avoid breakdowns

Dashboard lights signal problems that require immediate attention. These indicators include the check engine light, brake warning, oil pressure, battery, and tire pressure alerts. Ignoring these warnings can lead to mechanical failure or costly repairs. If the check engine light appears, schedule a diagnostic scan without delay. Even if performance seems normal, internal issues may be developing.

Before the extremes of winter and summer, schedule an inspection with a qualified technician. Seasonal inspections uncover minor issues before they grow into expensive problems. Ask your technician to assess belts, hoses, battery health, HVAC systems, and suspension components. In winter, confirm that the heater, defroster, and block heater operate correctly. In summer, check the air conditioning system and coolant levels.

At Begin Insurance, we help drivers understand the different types of auto insurance coverage available and how proper maintenance can impact their policy options. Our goal is to ensure each customer selects the right protection for their vehicle and lifestyle. We also emphasize how regular vehicle maintenance plays a role in maintaining coverage eligibility and reducing claim risks. A well-maintained car is less likely to be involved in accidents or suffer mechanical failures, which can positively influence insurance premiums and policy terms. To know more, contact us.
