Engine oils in Canada: what it costs, warranty and how to choose

Updated 4 November 2026

Engine oil in Canada costs roughly CA$10 to CA$70 a bottle, from basic conventional and diesel oils to premium full synthetics. The viscosity grade and the manufacturer's approval decide which oil your car can use, so describe your car in a free BlaBlaPrice request to get current offers.

Warranty: check the viscosity and approval

Repairs can be excluded from warranty when the wrong oil is used. GM Canada's limited warranty states that repairs caused by improper or dirty fuels and lubricants are not covered, and it refers the owner to the manual. Petro-Canada's lubricant handbook notes that both the oil viscosity and the service requirements of the vehicle have to be considered. The federal Office of Consumer Affairs also explains the difference between manufacturer's warranties and extended warranties.

Winter driving and the right grade

Winter here runs from December to February and summer from June to August, so tell the seller how the car is driven in winter. Ask which grade the manufacturer allows for cold starts, and whether a lower-viscosity oil is approved for your engine before you switch.

Buying here: litres, cities and delivery

Oil is measured in litres, so compare prices per litre rather than per bottle. Many listings do not state the volume, so check the size before you compare. Delivery to Toronto, Montreal, Vancouver, Calgary or Ottawa is agreed with each seller, so ask for the delivery cost before you compare offers.

What to write in your request

Give the car model and year, the viscosity grade from the owner's manual, and any approval the manufacturer requires. Say whether you need conventional, synthetic blend or full synthetic oil, how many litres one oil change takes and your budget in CA$. Name your delivery city so sellers can quote the delivery cost.
