New GTR, will drive about 6-7k a year. When would you recommend first oil change? At 5k it will be close to a year. Should I go with say 6 months instead of the 5k recommended in the manual?
5-6K or once a year, whichever comes first, is fine. I'm going to do my first oil change well before that, though, just because it is the factory fill. This is my first new car where I can do that.
I use one of these Air Power America Oil Extractors to extend intervals between oil/filter changes. Well worth the price of entry. Amazon or Walmart has the best price on 0W20.
edit: same company also makes an all metal version, but I've used mine for a while now.
That is correct. I have been draining and refilling oil around 3-4,000 miles and getting it changed along with the filter 3,000 miles later. My last vehicle was a pain to change oil in, with skidplates that need to be removed. I'm glad to hear it's easier on the CX.

What I*ve always done...
1500-2k first oil change
5k second oil change
Then carry on oil changes at whatever interval you decide to use
Yes, because the factory fill has very high content of molybdenum.I thought Mazda recommends running the factory oil for 5k mikes and changing before has no benefit?

This makes sense because 2.5T uses 5W-30 oil instead of 0W-20 for 2.5L, and Mazda doesnt make Mazda moly oil with 5W-30 viscosity.
Why dont you use Flexible oil change interval, which is up to 7,500 miles or 12 months whichever comes first, and is recommended by Mazda?New GTR, will drive about 6-7k a year.

Changing oil more often with right oil is good to the engine, but bad to the environment because oil is a non-renewable and dwindling global resource. It had been discussed before, that more than half of the used oil recycled actually burned even in California!Changed at 2k with Mazda moly 0w20, then again at 5k with Idemitsu Zepro 0w20 high moly (supposed to be same as Mazda oil).
Only like to change early to get break-in wear metals out.

You don't think 12 months is too long for first change? I don't know, that's why I'm asking.
Mazdas oil life monitor used for Flexible OCI will start to calculate time since the vehicle left the factory from my experience of driving a couple of loaner CX-5s from my Mazda dealer. So if you drive minimum miles on your CX-5, the Oil change due notification should be displayed 12 months from the assembly date, which may be mean 6~10 months for CX-5 owners due to the time for transportation and sitting in the dealers lot. Of course you can always change factory oil earlier as long as you feel comfortable, just remember to reset the oil life monitor after the oil change.You don't think 12 months is too long for first change?

I used to change factory oil at 1.000 miles because the owner's manual says so. Metal shavings from the new engine were the main concern. But I believe that's the thing of past with much more advanced manufacture process, and the owner's manual is no longer recommending early oil change for factory fill. Some companies such as Honda are even specifically stated in the owner's manual that don't change factory oil early as they use special break-in oil from factory!While it certainly is NOT necessary, I have always done my first oil change once I hit the end of the break-in period, on every car I've owned. That's just me, being ultra conservative.
