Also if you are doing the oil change yourself, poke a hole in the top of the filter 15 minutes before removing it. The anti-drain back valve in the Mazda filters works great and of you don't poke a hole, the oil filter will be filled with oil when you remove it and dump oil every where.

Poking the hole releases the drain valve and lets all that oil run down to the pan instead of the engine compartment.

Old rotary owner trick.
