Mazda CX 5 Is This Overfilled Enough To Be Concerned About ?

[DwightFrye]

It is well known that the 2019 Mazda CX 5 owners manual for the 2.5L turbo engine shows an incorrect oil capacity at 5.1 quarts with an oil filter replacement. Adding a 5 quart jug for an oil & filter change will only bring the oil up to halfway between the low and high dots on the dipstick and in order to fill to the max level dot on the dipstick it actually takes 5.5 quarts.

I wasn't careful in adding that extra half quart and may have added 2-3 ounces too much. Is this oil level on the dipstick enough to be concerned with that I should try and remove a few ounces ?

Not at all.

 

[atikovi]

Seriously?

A 1/2 quart wouldn't hurt anything. Dealers frequently put in 6 quarts because they use a flow meter that measures quarts,

 

[DwightFrye]

Yes, seriously. If I had a Fumoto valve my OCD would have me opening it up to drain a few ounces.
But if it's not an issue I'm not going to pull the drain plug just to remove a few ounces.

I really don't think so.

5 quarts is 160oz. An extra 2-3 ounces is on the order of 2% overfull. Probably in the rounding error range.

I wouldn't lose sleep over anything less than 1/4 quart overfull, and probably not over 1/2 quart overfull.

No worries. Good to go.

 

[Leo99]

I hope not. That's what my dipsticks looks like.

Avoid this issue in the future - dump in 5 quarts and be done. Between the dots is 100% FINE.

Yes! Why is halfway between the dipstick dots “incorrect“? Those dots are Minimum & Maximum levels, not “capacity full”. Add the amount required by the manufacturer and sleep well.

No, but dont do it again.

This times a million.

I don’t know what it is about the Mazda community but enthusiasts are all convinced that Mazda doesn’t know how to write fluid capacities in their manuals. Take a look at Mazdas247 and you’d be convinced that anything requiring lube in a Mazda leaves the factory under filled.

Not at all. I always found the 2.5L takes about 5.2 quarts. Some just put 5 in and call it a day.

take it easy.. don't lose sleep over that.

@haggler has a point...
Maybe you should go stand in the corner for 15 minutes...

 

[Racer4]

I vote like most you should be OK.

 

[Dave Hess]

I would not worry.

 

[Hypergalaxy]

A rule of thumb that I live by is 10%. Say if your car takes 5 quarts, you should not have any issues filling it over or under .5 of a quart. It should be stated that you really should never underfill your engine, but don't overfill it too much. Hope that this helps.

Where does your Owner's Manual state the oil reading should be located?
