synthetic is required. I recommend 5w30 oil and 5000 mile changes unless you drive mostly highway.
Using the wrong weight oil and changing it 50% more often than what's needed is dumb. Mazda's not in the business of giving out maintenance guidelines that lead to premature engine wear - that's a bad thing for them.
I can't agree strongly enough about that first oil change.
No way in hell should you run up to 7,500 miles on the factory new build oil.
I don't even wait 2,000 miles before changing it out.
The original factory oil will contain all of the crap from the engine break-in period, and needs to be dumped early.
I have always done this with all of my new cars, and I have never had a vehicle that burned oil later in life.
I would say do your first oil change after the break-in period, say at between 1,000 and 1,500 miles.
I sent ours in to Blackstone at 4,800 miles to get an actual, scientific analysis of it because I've always heard things like what you said. They said:
"The far right column shows average results from all of the healthy 2.5L SKYACTIV engines we've tested. In comparison, there was some extra iron, copper and silicon in this oil but it's actually less than we expected. In the first several oil changes, there's metal from the break-in process and silicon from sealants and lubes used in initial assembly, but it looks like this engine had excellent internal fit and finish right from the start. In other words, this CX-5 is off to a good start. Go ahead and bump the internal to 7,000 miles then check back."
So, I don't think 2,000 miles is really critical though it won't hurt either. I'm sticking with 7,500 mile max intervals too.
