Synthetic vs basic oil

If there was a non-synthetic oil that met the GF-5 specification then it would be fine to run non-synthetic. But, so far, no oil manufacturer has been able to achieve that feat.
2016s recommend 0w-20 in NA which is not available in non synthetic. Your MY required 5-20 which is available in conventional. Pennzoil makes one which meets gf5.

Watch out the oil dealer used for your oil change, especially if you have "free" oil change! Some dealers even use conventional oil if you don't ask! My dealer uses a no-brand 0W-20 synthetic oil for standard oil change. Just ask and pay some extra to get Mazda moly oil available at parts department.
Did they change the service interval for 2016 models? Although the oil burning issue was the main reason I changed my mind about the Subaru Outback the other thing that put the icing on the cake was the 7500 mile oil change interval as opposed to 6000 miles. Those extra 1500 miles makes a big difference when someone like my wife puts 25,000 miles on a vehicle a year.
I did an oil change after 500 miles. New engines tend to have high amount of silicone and metal wear-in materials after a few hundred miles. Maybe it's overkill but I have always done that on new engines.
Chevy released a bulletin stating that ALL new Z06 vehicles MUST change their engine oil after 500 miles due to the amount of debris during wear-in. Not doing so can result in an engine failure due to contaminated oil.

If my Mazda CX-5 was machined and built to the same standards Chevy uses, I might recommend changing the oil at 500 miles too!
Fortunately, we don't need to do that.

Honda has the following statement in the owner's manual for the "Break-in Period":
"Do not change the oil until the recommended time or mileage interval shown in the maintenance schedule."
Seriously, if you worry about amount of debris during wear-in, that's what the oil filter there for! Not to mention there won't be too much debris from a modern new engine (maybe except Chevy).
Honda claims to put a 'special' oil in their engines when they are manufactured and the oil will aid in the break in, so it should remain in the engine for the full interval.
