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

Pros: kept oil and water
Cons: burning oil, overheating
Vehicle: Mazda Protege

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 use Pentosin Pento HP II fully synthetic Euro Spec 5w-40 oil (made by Fuchs Oil in Germany). According to test data I have read it is a much better oil than the Mobil 1 oil. I believe that the 5w-40 oil provides greater protection against oil vaporization, as the OM642 can run at elevated temperatures leading to high oil temperatures, which tends to break down the oil sooner.

Pros: better than Mobil 1, greater protection, resists vaporization

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

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
