In the 2012 Mazda3, the recommended oil type is SAE 0w-20. The 2.3-liter engine requires 6 quarts of oil, while the 2.5-liter engine can hold 5.3 quarts. Oil plays a crucial role in keeping your engine components cool, lubricated, and preventing excess wear and damage by reducing friction between moving parts. The estimated cost for an oil change on your Mazda3 ranges from $60 to $80 for both labor and parts. It is advisable to schedule an oil change every 7,500 miles. Signs indicating the need for an oil change include increased engine noise, shaking while idling, excessive vehicle exhaust, a noticeable oil smell inside the car, as well as the illumination of the Check Engine or Oil Change warning lights.
For the 2012 Mazda 3 with a 2.3L engine, use SAE 5W-30 engine oil. For the 2.0L and 2.5L engines in the same model year, opt for SAE 0W-20 oil. The 2.3L engine requires 6 US quarts (5.7 liters) of oil, the 2.5L needs 5.3 US quarts (5.0 liters), and the 2.0L engine should be filled with 4.5 US quarts (4.2 liters) of oil.
