Engine oil OEM Mazda or IDEMITSU
I buy 5 OE Toyota filters at a time from Amazon ( approximately $6 ea ) Purchase Ow-20 Idemitsu oil from NAPA ( ships free to my home ) in the cost saving 6gal box ( 24 qts ) for about $125 with their online coupon. Use this in both my Avalon and my Tundra- both run like a dream.
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
I prefer synthetic myself in my CX50 Turbo, but Mazda engines aren't very picky overall.
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.
This is normal. Wait till it gets below 1k rpm. Modern engines do not need a lot of time to idle after cold start, the ECU handles it. Although, for a few kilometres, do not push very hard. The engine oil (0w-20 idemitsu) is thin, and needs time to lubricate well.
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.
I have a 17 grand touring and I use idemitsu 0w/20 and purolator b9ss filters.
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.
