“2018 Mazda CX-5 when I check the oil it is extremely over full and strong odor of gas when the dipstick is pulled out to be wiped off. It is like 4 inches above the max mark/ oil is very thin. This is an excessive amounts of gas in there.I warm up my car before leaving and drive it regularly everyday. This is very bad I read that gas is not a lubricant and washes the oil out of where it needs to be lubricating engine. It continues to happen. Checked manual to make sure I am checking it correctly. Says to get to operating temp. Wait 5 min to let oil settle back into engine then check it. …”

I've heard about it months ago from web sites that aren't supposed to notify me. Both you and Mazda have never notified me. Mazda was supposed to send out notices to the car owners 3 weeks ago. Why aren't I hearing about this?”
