CX-5 2.5 turbo 2021. Cold engine, after sitting overnight. Searched for another thread like this, didn’t find one. If it’s a duplicate, please direct me…

 

At that level you are about 3/4 quart or more over filled. I would guess you have filled the pan now above the flange. Technically because you have a balance shaft it would likely not cause any problems, but it is a bit higher than what I would recommend running the engine. Mostly because of the changing angles of the vehicles operating conditions.

The lower line and top line on the Mazda dipstick is the normal oil amount range. This means you can safely run the engine at either line or anything in-between.


In the picture I can also see that the dipstick may need to be cleaned with some solvent as you are getting a slight surface build up film that is not making the best readings possible. I would also recommend that a paper towel or newparer be used for wiping because clothing soap or detergents used in washing shop rags can cause a slightly false reading. Also try to do a oil reading when the engine has cold overnight and before it is first started the next day. Things most 99% of people don't know when reading the dip stick.

 

If that is the actual oil level on the correct dipstick I would consider it too high for safety. Aerated oil is the potential result.

 

Because the balance shaft will kill "cavitation" from forming and it would take extreme crankshaft speeds in a pan with a balance shaft to even worry about it forming.

 

The entity that changed the oil insists that that is correct with 5.1 quarts added. And they are the authority. I don’t agree either. I have a friend with an almost identical car. His is filled to that same level after an oil change at the same place.

I may remove some, or have the oil changed again somewhere else. Can’t find the Mazda oil anywhere close in quarts. Is any good name brand api m or n 5w-30 ok?

 

That and the specification the are posted in Factory Service Manuals as well owners mauls are based on a new engine that had never had oil. While they are close they are never in the hundredth value like what was told to you.
Now it may be that your dip stick for some reason is not correct, but I doubt it! Wherever you went getting your oil change should be a lesson learned and never go to them for service again!
If they are a fast oil and filter jack-in-the -box typ service company like jiffy lube where they set the oil fill meter (they use large 55 gallon or larger capacity revivors and use a pump fill system) as per the factory specification. YES often it will be slightly above the full mark on the dip stick with some vehicles but not as high as the picture you posted.

When you add oil after a oil and filter service it is always better to add close to the amount removed, (experienced auto service technicians can estimate close to the volume) then start the engine for a couple of minute turn it off and recheck the oil. Although the oil will strike across most of the first 1/4 of the dip stick someone experience can still see the surface tension point of oil to get an idea close enough where it is at and approximate how much more to add to get within the lines of oil quantity.

 

Most engines can handle a 1/2 qt over fill with no real problems. Some older American engines
could handle one quart overfill without problems. As with others here, that is a bit to much. Likely
not worth draining but use caution next time.

My 2¢

 

LOL where did you get this information? WOW maybe you had better do a little more fact finding about sump capacities?
Most oil pans exceeding the 5 quart capacity would have the pan filled and above the oil pan flange which would saturate the gasket and cause leaks. Naturally I am referring to pre 1989 or older American engines.

 

You guys are missing the part about them being the “authority” in determining proper fill. Who is the authority when you have a question about your new car? And please note. I didn’t do this! If I did it, no one would have ever seen it…

Here is another pic after a 20 mile expressway drive and sitting for 5-10 min. Dipstick has been sterilized and polished, and wiped off with a more appropriate shop towel.

 

can you post a picture of your dip stick wiped for a reference please
