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
Pros: kept oil and water
Cons: burning oil, overheating
Vehicle:
Mazda Protege
Red Line.
Pros: Red Line
Vehicle:
Chevrolet Camaro
I prefer synthetic myself in my CX50 Turbo, but Mazda engines aren't very picky overall.
Pros: Mazda engines aren't picky
Vehicle:

I like red line oils, because they have a bit more zddp which is nice for the rockers.
Pros: nice for the rockers
Cons: bad for catalytic converters
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
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.
Pros: more power, better mileage
Cons: car did not like gears
Vehicle:
Volkswagen Scirocco
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
zu viel Kurzstrecke. mach mal nen Ölwechsel und lass den wagen dann mal richtig auf Temperatur kommen.
Vehicle:
Mazda
they only say you can do that with their Mazda-branded oil. That stuff tends to be expensive.
Cons: tends to be expensive
Vehicle:
Mazda 6
