It bugged me that the Mazda branded 5W30 oil is conventional oil (in USA market) so yesterday I emailed Mazda USA thinking I would probably not get a response back, but to my surprise the next day (today) I received a reply. The reply was "Mazda recommends conventional SAE 5W-30 engine oil be used for your vehicle engine type to ensure that your vehicle operates as intended and to ensure maximum engine performance. If you would rather use synthetic engine oil for your vehicle please consult with the service department of your nearest Mazda to confirm this will not harm your vehicle." how friggin bogus is that?....Has any other car maker recommended a conventional oil in a turbo engine ever?
