Is there any service required such as spark plugs change, etc before 4 years or 60k miles? Is it easy to change the oil yourself in the Rx-8? I saw somewhere they use 5w/20 oil, is that true? Where can you buy that oil?

 

The owner’s manual has the maintenance schedule or register on www.Mazdausa.com
Yes it’s easy to change the oil
Auto parts stores is where you can get a filter and 5w / 20
