Hi all!
As some of you may be aware, I've been doing several UOAs on my CX-5 as I thought the OLM system was a bit optimistic. Check out this thread for review. I mailed my 4th sample on 3/6 so hopefully I get those results soon. In doing more research I stumbled on a Mazda specific forum and was made aware that the OCI was shortened starting in '18. I decided to dig into that statement, at first I thought that this was perhaps done since Mazda introduced cylinder deactivation for MY18, but that wasn't correct. The change actually occurred for MY17, this means that Mazda decreased the maximum interval on a largely unaltered engine. Has Mazda perhaps noticed that their OLM was letting owners go a bit too far and decided to scale back?
The 2016 2.5l produces 184 horsepower, whereas the 2017 produces 187. I can't find any materials which highlight mechanical changes made to earn this increase, I have however read that there were tweaks made to throttle/transmission response so I assume that these were software/electronic changes. If anyone is has more information, please share.
Below are the snippets from each respective manual.
