Engine oil OEM Mazda or RED LINE

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

Red Line.

I prefer synthetic myself in my CX50 Turbo, but Mazda engines aren't very picky overall.

I like red line oils, because they have a bit more zddp which is nice for the rockers.

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.

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.

On chilly winter mornings (SF Bay Area) the car did not like reverse or first gears. Subsequently switched to Red Line engine oil. More power, better mileage.

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.

zu viel Kurzstrecke. mach mal nen Ölwechsel und lass den wagen dann mal richtig auf Temperatur kommen.

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