Oil Change: Intervals, Synthetic vs Conventional

Engine oil is your vehicle's blood. Without it, every moving part rubs, heats up, and wears at insane speed. We see it regularly: engines that could have lasted 300,000 km destroyed at 150,000 km because oil changes were neglected.

In Montreal, our driving conditions — extreme cold, traffic jams, cold starts — are what's called "severe conditions." That means your oil works harder than elsewhere.

Recommended Oil Change Intervals

Forget the old "every 5,000 km" rule. The interval depends on your oil and driving:

• Conventional oil: every 5,000 to 8,000 km.
• Synthetic oil: every 8,000 to 12,000 km.
• Severe conditions (Montreal!): reduce the interval by 20% to 30%.

Always check your vehicle's owner's manual for specific recommendations.

Synthetic vs Conventional

Conventional oil: cheaper, sufficient for older vehicles with normal driving conditions.

Synthetic oil: more expensive but superior in every way. Better cold protection (-40°C), better heat resistance, lasts longer, and reduces friction.

In Montreal, with our -25°C winters and +35°C summers, we strongly recommend synthetic for most vehicles.

How Much Does an Oil Change Cost?

• Conventional oil: $50 to $80.
• Semi-synthetic oil: $70 to $100.
• Synthetic oil: $80 to $130.

These prices typically include oil, filter, and labor. Your engine is a $10,000 to $30,000 investment — an $80 oil change is the cheapest insurance.

Signs Your Oil Needs Changing

• Black, thick oil (should be amber and fluid).
• Louder engine noise.
• Oil warning light on.
• Oil level dropping frequently.
• Burning smell from the engine.

Key Takeaways

• Montreal = severe conditions. Change your oil more often.
• Synthetic recommended for most vehicles in Montreal.
• An oil change costs $50–$130 — far less than a new engine.
• Also check your brakes and alignment during maintenance.
• Never exceed the manufacturer's recommended interval.

Frequently Asked Questions

Can I switch from conventional to synthetic?

Yes, no problem. It's even recommended for better protection.

How do I check my oil level?

Engine cold, pull the dipstick, wipe, reinsert, pull out and read. Level should be between the two marks.

Does the oil change include the filter?

Yes, we always change the oil filter with the oil change.

What happens if I don't change my oil?

Oil thickens, loses lubricating properties, and the engine wears prematurely. At worst, the engine can seize.

How long does an oil change take?

About 30 to 45 minutes. Use the time for a quick check-up.
