Here’s the latest version on the TSB mentioned as there were 2 older versions:
Yes oil consumption could be caused by many things. But for OP who has a 2021 CX-5 with 2.5T which is clearly listed on the Low Oil Level Warning Light TSB, we should suggest him to take his CX-5 to a Mazda dealer ASAP as the problem almost certainly is caused by defective exhaust valve stem seals. The fix is very expensive and if there isn’t this TSB this kind of oil consumption won’t meet the 1 quart per 1,000 mile industry guideline on oil consumption problem and none of the car manufactures would do anything about it. I believe @Tchman2016 did a right thing at the first place to suggest the OP to visit the Mazda dealer based on the TSB. Don’t waste the time to check or do anything else trying to resolve the oil consumption issue by yourself if there’s a TSB and you have warranty to cover the diagnosis and fix.
That's fine, it doesn't matter if you add oil because the light came on already and code is already set. In fact you are proactively protecting the engine from further damage by adding oil. Nobody's expected to drive around with low oil until they get to a dealership!
Yes when OP’s CX-5 is having a “LOW ENGINE OIL LEVEL” warning message and an engine oil level warning light on in the instrument cluster, a DTC P250F:00 should have been stored in memory.
Unfortunately it’s just like I guessed (the code SHOULD be stored in memory). It usually takes about 4,500 miles to use up a quart with damaged exhaust valve stem seals which most likely is about time to do the next oil change. Just make sure don’t add any oil when the Low Oil Level Warning Light is on and visit your dealer ASAP.
They either did not look at the history codes in the PCM or they did not scan the vehicle and jusy told you there were no codes because the indicator light wasn't actively on. As soon as that light comes on it sets a code. It is a fault code and the PCM wouldn't turn on that light if it didn't detect an issue. I've run into this issue before with my vehicle brought to a dealership when there was a fault light on the dash for which I took a picture of so there was no dispute. I have a high end scanner and there was a clear fault code stored in memory when scanned, however the dealer told me they scanned it and there was none. It was BS because I scanned my vehicle again after getting it back and the code there clear as day. Bottom line is that they are either liars or incompetent or both. They probably don't want to deal with that right now because the warranty time is much lower than actual book time to do the job. They also probably don't have the master tech/shop foreman available that is required to do the job either. These dealerships like to prioritize $100 oil changes before actual work. It's a very sad situation that most competent knowledgeable techs have left the dealers or the industry entirely because of the horrific pay system and treatment by their employers. Nobody wants to be treated like dirt.
Dealerships are strange. They know your make/model year falls into the valve seal issue, they can even check for a leak with a simple test. Why do they resist doing the work. I guess it is the reason Tchman2016 said. Burning oil can potentially clog up the catalytic converter.
Yes, that is how they explained it to me.
Well said! You simply can’t trust those dealers nowadays!
