Engine is consuming/burning oil. I have needed to add 1 qt of oil every 3-4k miles, since purchased new. Car now has 25,000 miles and I have added oil 6 times. Ive called the dealer(Classic Mazda in Mentor Ohio) and they insist this is normal and there is no issue with the engine. Yet, I read on the internet that this is a known problem.

I have just about 8800 miles on my Mazda CX-30 Turbo after a year and 5 months. Suddenly had my low oil engine light come on. I pulled over and the oil is barely on the tip of the oil stick. My last oil change, which was also my first, was completed at 4937 miles from the Mazda dealership.

Excessive oil consumption. I bought this vehicle new from a Mazda dealership, with factory warranty. The check engine oil light came on at approximately 6800 miles, 3750 miles after the first oil change. An additional quart of oil was added. I brought it back to Mazda to confirm no oil leaks, which they confirmed. They were made aware of the Mazda service bulletin for excessive oil consumption, which they acknowledged, but indicated they will monitor as there is no solution from the factory.

low oil indicator keeps coming on at 3k miles and 8k miles. some times the oil is slightly low. The manual says to sop driving immediately, but that is not always possible.

My car is burning a quart of oil every 1500 miles. I have taken it to the dealer three times. They say that they know about the problem but don't have a fix. I am afraid that the engine could seize up during driving, causing a accident.

Driving home from work today I got a "low engine oil level" alert/warning. First time this has happened. I have approx. 15,500 miles on my vehicle and it was serviced on 3/22/22 (11,828 miles). That service included a full oil and filter change. I see it has been noted that there is an oil leak with this particular vehicle but Mazda has not been able to figure out what is causing it. Just wanted it to be reported

I have the 2.5 liter turbocharged engine in my CX-30. It currently has approximately 18,000 miles after a little over a year of ownership. So far I have had to put in 3 quarts of oil in that time. The engine/low oil indicator comes on about every 4,000 miles. When I check the oil, it shows that it is down a quart. I have taken it in for regular service (oil and filter, tire rotation) twice now, and have brought this to the attention of the service advisor who tells me that this is normal for turbo engines. I disagree with this assessment. I will bring it up again later this week when it goes in for its third service. No new car should consume oil at the rate this one does. I have also observed blue smoke from the exhaust on start-up. I owned another turbo Mazda model a few years ago that did not do this. I have found what appears to be a technical service bulletin from Mazda regarding all turbocharged 2021 models built prior to September 2021. (TSB-01-012-21) My greatest concern is that this will only become worse and end up causing major damage to the engine and/or make the car unsafe to drive.

Low engine oil after 4630 miles!

- Bellflower, CA, USA

The contact owns a 2021 Mazda CX-30. The contact stated that the low engine oil warning light was illuminated. The contact stated that the app used for alerting vehicle failure also notified the contact of the failure. The failure occurred twice. The dealer was contacted and informed her that it was a known issue however, there was no recall. The contact had not taken the vehicle to the dealer. The vehicle had not been diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage 3,100.

- Warwick, NY, USA

While driving, Low Engine Oil light illuminated. Vehicle has 9968 miles at time of incident and had one oil change at 5873 miles. So in the span of 4095 miles, engine had burned enough oil that none was showing on dipstick at time of incident. Vehicle was taken to dealership where it was confirmed that there were no leaks and the engine was consuming oil at a rapid rate. Mazda has issued a bulletin to dealerships concerning this issue, so the company is aware a problem exists with this engine. Had the oil level decreased to a low enough level, the engine could have feasibly failed, which could have resulted in a dangerous situation if it happened on the highway or in heavy traffic. Mazda currently has no fix and encourages that oil be added when necessary. Given the unpredictable frequency of the oil consumption, this does not feel like a safe solution, putting the onus entirely on the owner.

At about 3,605 miles, I received a low engine oil warning. The car is only 4 months old. When i took the car to the dealer, apparently there is a TSB that was issued in October 2021 about the problem. I bought the car in November was not advised of this issue. At this time, it appears at this time Mazda is unable to determine the root cause. It appears that I am to take the vehicle to the dealer every time I have this experience. I am worried about the potential impact and the lifespan of the engine.
