I didn't know that. What was the reason for redesigned pistons and rings? That was for 2017?
They redesigned the piston edge to reduce hot spots and did a little bit on the crown from what I understand. The 17 got a new ring pack which included a very thin oil control ring. I saw a Dave Coleman video on it but have had trouble finding that again.
18 of course brought cylinder deactivation and they updated GVC to Plus.
You are going to have to update us when you take her out for a nice long drive.
Very interesting. All the Mazdas I have had (2007, 2014 and 2015) never burned a noticeable drop of oil. I attribute that to the type of rings Mazda uses. Have there been any reported any oil consumption issues since they changed the rings?
Will do.
