I am uncertain of your location, however the Mazda dealerships in my vicinity do not impose much higher fees for an oil change compared to local oil change establishments. For approximately $110, the dealership will perform an oil and filter change, inspect and replenish any necessary fluids, examine the air and cabin air filters, rotate the tires, and wash the vehicle. The local oil change establishments charge approximately $80 alone for the oil and filter replacement. Performing the oil and filter change independently would incur a cost of approximately $45 to $50; therefore, I find the dealership's pricing acceptable.
