🟡 Mazda CX-5 Mk2 2019+ SkyActiv-G oil dilution cold climates

Engine oil level rising above maximum on the dipstick with a petrol smell. The SkyActiv-G engine in the Mk2 CX-5 uses a cylinder deactivation system and unique combustion strategy that can cause fuel to wash past piston rings in cold climates during short journeys. Mazda issued a software update improving cold-start fuel management. Always check oil level regularly and avoid repeated very short journeys in cold weather. Mazda provides extended warranty coverage for affected engines.
