Middle son bought a 2018 Yaris ia (Mazda 2) with a 1.5L Skyactive-G engine and 6-speed auto for commuting to work (70 mile round trip mostly rural highway with a 2 mile 35 mph max dirt road on our end). Okay this is our first Direct Injection engine in the family and I haven't dealt with Mazda since I was much younger (Rx7, Autocross, sounds of oil pressure and rev warning buzzers, sigh). So first question
1. What are your recommendations for oil change interval on the engine? From what I have read 5000 miles for city drivers, up to 7500 for highway drivers. Was planning Pennzoil Platinum for oil like rest of our cars with Wix filter
2. Any recommendations on intake manifold cleaning for valves? On the Scion forums they talked about every 30000 miles have Mazda do intake cleaning, however others have had no problems and just due Italian tune-up (easy with him, just tell him to put in sport mode when merging in the city).
3. It has a sealed Automatic Transmission! Toyota tried this with their whole life of vehicle AT fluid spiel on oldest son's Toyota, but I changed the AT fluid in the Toyota anyway and it looked like crap coming out, much better now at 30000-60000 interval (when I can get him to do it). So what is your recommended change interval and fluid ( I use Valvoline Maxlife in all our other vehicles, except for the Crosstrek of course)?
4. Spark Plugs? Stock? Deferent change interval?
Comments: The more I read on this engine the more I am impressed. I am even tempted to replace a planned purchase of Rav4 for the wife with a Mazda equivalent (is there a Mazda equal) to replace Her 2012 Honda Odyssey ( I will never buy another engine with VCM, worked great after I disabled the VCM). Tho next vehicle needs to be able to store a full-size spare. Speaking of which I need to find a full-size rim for Son's Yaris for his spare tire, and Air pump, and start putting his emergency kit together.
