Remeasure with a cold engine with car sitting approximately level. If not more that 3/8 inch leave it alone.
EDIT: Found the oil, which is same price as walmart but amazon ships for free

Paired it with the pure one oil filter.
Thanks for listing the tools needed. I won't be doing an oil change myself until some time in 2016, but it is good to know about the wrenches. The deal I got when I purchased my CX-5 included three oil changes at no charge from the Mazda dealer, and at the rate that I am driving I figure that will take me to 2016 easy.Owners manual on 2015 CX-5 says 4.8 US quarts. I put in the full 5 qt jug, and as others have said, that brings it up about 2/3 the way to the full line, perfect. That makes it a pretty easy process to just buy a 5 qt jug each time.
I expected not being able to get the filter off by hand the first time, and I couldn't. The local O'Reilly auto parts store had a Penzoil, 19902 Code C, 'Oil Filter Cap Wrench', for about $6 that worked perfectly. (65/67 mm, 14 flutes). It's a snug fit, so I hammer tapped it on to the bottom of the filter until it was fully seated to the bottom end. I also bought a long arm 8mm allen wrench to get the plug out.
FWIW, I used the OEM filter (PE01-14-302A) and Castro 'Edge' SAE 0W-20 Full Synthetic. Happy oil changing.
I notice Med Mazda (mazdaparts.org) have the kits for $40 + shipping or free shipping over $100. Not sure if that's a reputable site. I wouldn't mind paying the extra $7 for Mazda oil, just not ~$20+ when compared to Mobil 1 as I change oil a bit often also (4 to 6 months) since I do drive about 15k to 20k miles a year.
They are reputable. I bought some accessories from their eBay store.
EDIT: I am picking up 5 quarts & a filter tomorrow from dealer while I am getting my BT module replaced.
I bought my moly from my dealer again. Filter was 7.99 and they charged me $7.09/quart. I picked up 5 quarts. Total before tax was 43.44.
Wow, your dealer is fairly cheap for the oil...
My past 2 total was $55 I believe, if I didn't mention/showed the old receipt that I got the price of $55 first time, I would have been charged $70 for 5 quarts of oil and the filter...
But now, I ordered 3 sets of oil from Med Mazda eBay.. A lot cheaper than my local dealer for sure.
