I'm in the market for a new vehicle now because my 2018 mustang had a coolant leak and needs an engine replaced. Just took an uber to the dealer to get the loaner yesterday, and rode in a 2012 Mazda CX-9 (v6), driver said it had about 190k miles on it. Was going to add the CX-9 to my shopping list until I saw this thread they just don't make them like they used to

I had a couple of tiny leaks in my van... there was some kind of pan that was catching the dribbles so I never even knew I had the damned leaks. Maybe your car has a pan thingy too?

Mustang needs a new engine at 7 years and 71k miles
ETA: it's getting a new engine courtesy of extended warranty, if anyone wants to take a mustang with a new engine off my hands

We have a brand new CX90 and the low oil light has come on multiple times, they did an oil consumption check and it didn’t even make it to the 1400 miles to measure the level before the light came on again. It’s currently at the dealership, will report back when I know something.

You're good, I meant add the CX-9 model in general to the shopping list 
It's looking like a Rav4 (need something for the kid coming in January) but definitely open to shopping around other similar models. Hoping your problem is a relative non-issue!

If it's down a quart after 4K, that isn't terrible.
2 or more quarts, Id be concerned.
I've never seen an oil light come on just being low a quart though.
Lights can be se sensitive, so if you took a corner at decent speed, it could flash on, if you're low.

Correct.
My guess is it's down almost 2 quarts.
LMK what cold level is.
Also, be certain correct wt oil is being used.
Those engines are tight and like the thinner wts.
I like Castrol or Mobil 1.

I wouldn't worry until it comes on again.
Here's why.... You don't know the starting oil level when you bought the car and you have no indication if it were a little bit low when you bought it or when/if the oil was changed when you asked.
Change the oil. Take a picture of the oil level on your dipstick for an absolute reference. Do this once a week so you can quantify the change. Pay attention to any odd smoke that may occur on startup as mentioned earlier.
You're likely fine. Unless there is some kind of weird damage, 65k isn't enough to wear a car out nowadays.

My Expedition has been burning oil for 100K miles. Has 180K on it. I check the oil every week and put some in if need be.
Start buying cheap oil. Keep a funnel, a quart of oil, and some napkins in your car. Keep the funnel in a plastic bag so oil doe get on stuff.

I have a 2018 Mazda CX-9 with about 65k miles on it. We purchased it about 4-5 months ago. Had it checked out by our trusted local mechanic before we bought it and had them do an oil change right after we bought it. No issues until the oil light came on today. The oil level seems a bit low but not too bad. It does not leak any oil that I can see and it runs great. We are due for another oil change in about a month or 1k miles. Spoke to our mechanic and he just suggests we bring it in for the next oil change. He didn’t seem concerned. Should I be?
If the oil level is less than a quart or so low between changes and it runs good it is probably a bad sending unit. Moderately low mileage on what is a pretty reliable engine. Unlikely to be a bearing or something major.

We had a Camry that started burning oil and eventually blew the head gasket .
It'd be highly unusual in my experience on any engine that burning oil would lead to a blow head gasket...I am not sure how it could but it probably could. Most likely the engine was burning oil and overheated or froze in a completely unrelated incident akin to having a tire blow out on a car that used oil. If the oil level got low enough to cause the engine to overheat to the point that it blew a head gasket the engine would have probably come apart in spectacular fashion before the gasket blew...but its theoretically possible I guess.
Most folks do not remember it but it has not been but about 25 years or so that burning a quart of oil or less between changes at 5000 miles was pretty much normal in cars. Fords were NOTORIOUS for this. Machining tolerances have eliminated it almost completely in modern engines but it was more unusual for an engine not to be half a quart low or so between changes than it would be for it to be full. I have driven a pile of cars that would burn a quart per tank of gas....and put a bunch of miles on them while they did it. It was more or less normal.

we haven’t seen any smoke. If it were burning oil wouldn’t it run kind of rough as well as smoke?
If it was burning a bunch it would...they all burn some. It is less than 5000 miles between oil changes and it less than a quart low it is fine. A pain in the arse for sure because you probably ought to check the oil at least every other fill up (should check it every fill up but almost nobody does anymore) but running an engine a quart or so low may mean it will run 1-2% fewer miles over its lifetime...especially if it is a quart low over 5000 miles. If it is a quart low the entire 5000 miles it would be slightly worse but not much.

Some motors just burn oil too.
Very few do not burn some oil....

Hard braking, hard turn, AC cycling, all manner of things can cause an oil light to come on in a car. They are an electrical device so dirty connections are often the culprit. I wouldn't be too concerned about it if it is less than a quart low between changes. I wouldn't be overly concerned if it was a quart low at 2500 miles but that is because I have driven many cars and trucks that would burn a quart or so between fill ups.....and drove them for many many miles.

Ask your mechanic if he reset the oil change warning light. That model Mazda may also have an oil change interval setting that may be set low. I had a 2020 Mazda 6 and found a 3k mile interval. The owner asked for a 5k interval and I set it to that.

May just be sensitive to low levels. My sister had a 2013 cx-5 and the brake fluid was just barely in the low and the light popped on. I topped it off, didn't need much and it went out. Never checked it again....oops.
Unrelated to engine oil...
Brake fluid levels can drop as the pads wear. When they are getting thin it takes more fluid for the caliper to push the pad to the rotor. If you add some just remember to remove some after replacing pads with new ones or the reservoir can be overfilled. Usually though if after replacing pads fluid is at max level it will not go below the min level due to pads.

I've never had a street car or track car do thst unless they were already low on oil.
It is extremely difficult for those connections to get dirty on anything built since the 90s.
They're pretty well sealed from thr environment.

My daughters Altima was burning oil and blowing smoke at certain times, especially after idling for a while. Ended up being the PCV valve. $20 part
