Transmission Fluid

To protect your transmission and keep your car running for as long as possible, have the transmission fluid checked every 40,000 miles.

Oil Changes

Change the oil in your Mazda every 5,000 miles. If most of your miles come from highway driving (driving at a set speed for long intervals of time), you may be able to change the oil every 6,000 miles, but if you do most of your driving in a city or suburban area, check your oil every 2,500 miles just to be safe.

If you change the oil yourself, remember to change the oil filter as well. If you take the car to a mechanic to have the oil changed, he should change the filter when he changes the oil.
