Quick summary for us Mazda 3 owners: Avoid the ones with automatic transmissions. Keep in mind there engines are not as "strong" as others. If oil isn't regular changed every 5K miles, you risk your car being an oil drinker.

What’s with Mazdas burning oil?

Still will rather a MAZDA3 over ANY Toyota Corolla or Hyundai i30.
