As far as carbon buildup goes, it's one of the GDI engines that doesn't have too much of an issue. I would suggest running the engine hard now and then. Hi all, new here trying to diagnose a problem. 2012 Mazda3 Skyactiv 2.0L vin 7, bought brand new December 2012. Started running a little rough around 75k miles and dropping mileage. Changed plugs to NGK Iridiums around 80k miles. Mechanic told me that one plug was so shot, it was barely even sparking. Engine seemed to even out for a bit, then Harbor Freight sells these. $28 for the kit and $9 for the fluid, if my memory is correct. You plug the bottom 1 way valve into the coolant reserve tank with the engine warmed up and running. There needs to be 2-3 inches of clearance above the coolant and the top of the reservoir to draw in air and not coolant. 573 posts · Joined 2012. #1 · Mar 25, 2013. With the known fact that some other manufacturers' direct injection engines suffer from power/economy robbing deposits on the intake valves, I decided to see if the Skyactiv G 2.0L in our Mazda 3's was also prone to this issue. These deposits form from oil vapors vented into the intake by the PCV 1037 posts · Joined 2012. #1 · Jun 12, 2012 (Edited) 2012 mazda 3 five door, skyactiv, 1500miles. Well two days in a row now while making a low speed turn (less than 10mph) the power steering quit working. The first time it recovered after the turn was completed. The second time was today while making a "U" turn today. 9 posts · Joined 2010. #8 · Mar 5, 2012. The Skyactiv engine has been designed to minimize fuel useage and several of these design characteristics would tend to make it noisier. In addition to the previously mentioned fuel component noises, the block, crankshaft, bearings, and valve train have been lightened and reworked to reduce friction DORp8A. So naturally, the question comes to mind: “Are Mazda transmissions reliable?”. Mazda vehicles were notorious for automatic transmission problems in the early 2000s, especially the 626, Millenia, and MPV models. From 2005 to 2020, Mazda automatic transmissions in Mazda 3, 5, 6, CX-7, and CX-9 have been very reliable with few transmission issues. Cons: The way the skyactiv engine is built makes it a poor tuner engine. The high compression ratio makes mods like turbos and supes potentially hazardous. After market modifications to the engine without professional input are ill advised. Less hazardous mods like a cold air intake don't provide much added power, again because of the already replace engine 2013 mazda 3 sky 2.00 l -----Hay everyone I m new to this site I m wondering if someone could help me with my problem.

I have a mazda 3 2013 with skyactiv. Got a P0010 code, john aka eauto, The Car Guy. Mazda. 26,455. Experience: ase tech,shop owner. So in that unscientific poll 21.7% CX-9 owners were having coolant leak problem and got their 2.5T engine replaced. So assuming all SkyActiv-G 2.5T’s are created equal, we should see 21.7% of the CX-5’s with 2.5T are having the same issue. But in reality, we’ve only seen reports here on 2.5T CX-5 with low compression issue on certain
