Just purchased a Mazda6i for my daughter. For the first oil change on a new vehicle I like to change it somewhere between 500 and 1000 miles, with filter change.
For the 6i Mazda recommends 5w-20, so that is what I used. I was planning to use 5w-30 but my daughter pitched a fit because it just wasn't the exact oil that was suppose to be in it. No use in trying to explain so I figured if she was that concerned with her new car I would do exactly what was recommended. I happened to find a case of Motorcraft 5w-20 Blended Synthetic at Wally World at about $1.50 a qt.
I plan on going to full synthetic at about 7500 miles.
