"low engine oil level since i bought it in september 2021. i’ve had it at the dealer three times and they’ve said there are no codes on the car but they are on my mazda app. they want me to drive it over a hour away with low oil to prove to them that the engine oil is low. i did this, shut the car off, the light went off and when the engine oil level was checked it read one quart low."

"“low engine oil level” light comes on periodically for last several hundred miles. dipstick show oil level to be appropriate."

"the low engine oil warning light keeps coming on, and there’s appears to be no visible leak. i add about a quart each time this happens and it does fine for a while. the last time i took it to the dealership, i told them about it. they just said they didn’t see a leak and not to worry about it. ultimately the issue is how will this impact the longevity of my engine?"

"using a quart of oil every 1,500 miles. known oil consumption issue with the 2021 mazda cx 30 turbo 2.5 engine"

"the low oil level light/sensor came on before it was time to get an oil change (the recommended 4600 miles). this is super dangerous as it can cause major engine issues. i took it to the dealership and the dealership stated "they are having problems with these cars-they are burning too much oil so there is going to be a replacement valve once they have one made and you'll need to come back in to have it replaced -it will be a big job since it's part of the engine"."
