The 2007 Mazda3 requires 4.3 liters (4.5 quarts) of SAE 5W-30 synthetic engine oil, which lasts longer than conventional oil and doesn't need to be changed as frequently. Mazda recommends an oil change every 7,500 miles, but if you live in a dusty area or take a lot of slow-speed commutes, you might need to do it more often. By changing the oil before it becomes low or old, you can prevent costly damage to the engine. Oil lubricates moving parts, keeps the engine cool, improves performance, and boosts fuel efficiency. The average cost for an oil change for this car is $120 to $150, with labor accounting for $50 to $70 of that total. Doing the oil change yourself can save you some money.
