The Mazda dealer that I bought/service the car from sells about 50-60 CX5's a month (pre-COVID while they still had cars to sell) and I am the first CX5 (first 2.5L N/A SKYACTIV G for that matter) with an oil leak at the dealership. Based on this rudimentary analysis, I would say it's not a widespread issue across the 2.5L N/A motors w/ CD. 2012, the number of models that fully incorporate Skyactiv Technology has increased. Starting in 2019, Mazda has been introducing new-generation technologies, including the Skyactiv-X engine, set to become the world’s first commercial gasoline engine to use compression ignition.*1 This unique new-generation engine combines the advantages Oil leak on top of engine bay (Skyactiv 2.5) Garage: 2014 Mazda 6 Grand Touring (6AT) & 2018 Mazda 3 Grand Touring (6MT) California.

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 started running rough again. This engine closely resembles my hallowed 1990 BMW 325i’s legendary 2.5L Inline 6 for power/torque delivery and responsiveness characteristics and is darn near as smooth at every RPM. Of course the mazda engine is making much more power and torque. What a wonderful engine this Mazda 2.5G Skyactiv is! Anyway the extra information I wanted to add is that on picking up the car a different service guy said that it is a different/new part that has been fitted and that Mazda have extended the warranty on the original part to 10 years/200000km. According to Mazda, the 2.0-liter SkyActiv-X delivers up to 30 percent more torque than the equivalent SkyActiv-G 2.0 unit while reducing fuel consumption by as much as 30 percent. Mazda is jerking us around until the warranty expires. This car will be nearly worthless when I pay it off because if it burns oil that bad brand new, it's going to require weekly oil changes by then. Ive been a Mazda guy for decades.

In 2021, all Mazdas (excluding the CX-3 and CX-9) will have two powertrain options. The oil requirements are different for each. The 2.5 non-turbo takes 0w20 (synthetic), the 2.5 Turbo takes 5w30 (non-synthetic). The dealer will use the appropriate Mazda Premium (Idemitsu) oil, unless otherwise requested. wfHUE.
