No, but I did keep 2 quarts of oil and a gallon jug of water. My Mazda Protege was notorious for burning oil and overheating

Change the oil at a minimum, and do it regularly. Use a quality synthetic high mileage oil and change it again in a couple thousand miles, then change on regular 5k mile intervals.

Pros: quality synthetic oil

Vehicle: Mazda 6

I have run 0w20 in my 2013 Mazda 3 skyactiv for 244,000 miles. It doesn't burn or leak any oil between changes. I change the oil and filters every 5-6,000 miles.

Pros: no burning or leaking

Vehicle: Mazda 3

Mileage: 244000 km

I personally am changing my own oil with full synthetic on my 23 2.5T every 6000 km or so. No need other than peace of mind for me. Doing it myself only takes 30 minutes and $35 in oil, filter and crush washer.

Pros: peace of mind

Vehicle: Mazda 3

Mileage: 6000 km

For [Naturally-Aspirated Skyactiv engines](https://en.wikipedia.org/wiki/SkyActiv), it is highly recommended that you use Mazda's own(Idemitsu) high molly GF-5 0w-20. [Arguably it is one of the best oil for skyactiv engines](http://www.cleanmpg.com/community/index.php?threads/45295/#post-357910).

Pros: best oil for skyactiv

Vehicle: Mazda 3

Part number: GF-5 0W-20

I used kendall 20w50 in race engines, though those saw 7-8 grand shifts, and lasted about a year.

Pros: lasted under harsh conditions

Many reputable rotary shops have tested numerous oils over the years, and agreed that the bearings do not have adequate protection with 5w-20 or 5w-30, especially if you track the car or do any spirited driving regularly.

Cons: inadequate bearing protection

they only say you can do that with their Mazda-branded oil. That stuff tends to be expensive.

Cons: tends to be expensive
