Picked up a ‘19 cx5 touring awd for my lady (and as our family car) a few weeks ago, and want to find the "best" oil for this application. Mazda only specs an api-SN 0w20 as suitable. Factory fill was changed with Mazda 0w20 synthetic with moly at about 2400 miles (to get break in metals out), and will be changing oil again at 5k, followed by 5k intervals thereafter.
Only caveat is that these engines (‘18-up) now have cylinder deactivation, and there have been some reports of rocker arms falling off the CD adjuster at high rpm's due to insufficient oil pressure. Apparently the problem is widespread enough that Mazda has issued a recall for a software update that supposedly helps better regulate oil pressure.
That being said, Mazda oil with moly is a bit on the pricey side ($7-8/qt at best), so I'd appreciate some recommendations based on the following:
- higher moly if possible
- perhaps on the thicker side of 0w20 and shear-resistant to keep oil pressure up
Car will see about 35k miles per year, and was originally planning 7.5k intervals until the potential rocker arm issue showed up. What do you guys recommend?
