    How to change a Mazda 3's oil?

    Drive the car gently for 10 minutes to get the oil warm. Park the car on level ground, lift the bonnet and loosen the oil filler cap on the engine, and slide a tray or pan with at least 5-litres of capacity under the car. There is a flap held on by a couple of plastic screws protecting the drain plug and oil filter. You may not be able to reach the drain plug on the sump underneath the car without lifting the vehicle. If this is the case remember to use multiple chassis stands to securely hold the car in the air, and to ensure the car is as level as possible (so you might need to jack up the rear of the car to keep it flat). After 10 minutes the oil should have stopped dripping from the sump plug so put it back it and snug it tight - don't over-tighten it as you could strip the thread in the sump which would require removing the engine to fix! Remove the oil filter, allowing it to drain, and ensuring the rubber seal isn't stuck on the metal mating surface. Once drained wipe a smear of fresh oil on the new oil filter's rubber O-ring, fitting it a quarter-turn past snug. Check on your owner's manual for how much oil is required for your particular engine, and what grade of oil you should use.
