Do you know if skyactive X have carbon build, have anyone ever heard of this problem on this engine? I was also asking members with Mazda 3. I'm looking to buy a CX-30 and i was wondering how is this new engine regarding this issue. Thanks.

Had a 2014 Mazda 3 before I got the CX30 and had no problems with carbon build up. Always ran 95 octane (93 stateside) in it.
