The average cost for an oil and filter change is between $14 to $28. Labor costs are estimated between $0 to $1 while parts are priced between $14 to $27.
Now, just do the math. Most places in Canada will charge you at least $80 and often $100 or more for an oil change using bulk synthetic oil that is of a lesser quality and name brand than Mobil 1.

If you go to a dealership or higher end garage then you're probably looking at $25 to $30 plus the cost of your oil.
