This dealer states that some motors will burn up to 3/4 a quart every 1000 miles. I hope they will help me if this applies to my motor.
Some motors may, that is where you should change brands of oil to see if you can find a brand that doesn't have major consumption issues. The additive package in each brand of oil is different.

I plan on getting the oil changed every 5K miles (around every 2 months at my rate) and I want to use synthetic after my 1st Dealer "check up" oil change at 5K miles. Does this sound adequate? Or should I possibly begin with a different plan? This car needs to last me at least 6 years so I want to baby the hell out of it.
You are using synthetic oil now, no need to switch. Just stay with 0W20 as Mazda recommends.
