It’d be interesting to see how much oil you need to change the oil on your 2.5T?

Obviously that would depend on where he prefers the oil level to be on the dipstick.

For some reason I can't seem to find the previously available approximate oil capacity listed in the 2020 CX-5 owner's manual or my 2018 CX-9 owner's manual (both online versions), but logically, an approximation makes the most sense based on both user preference and the range considered "OK" between the MAX and MIN marks on the dipstick. When you also consider other factors like drain time, oil dilution/consumption, prefilling the oil filter, etc., an approximation makes the most sense.

You can say the same about torque specs, to a degree. Stating a range instead of a specific value accounts for the variance in accuracy that some consumer-level torque wrenches may have, as well as any variances that may occur from a torque wrench that may not be calibrated perfectly. It would make sense to assign a hard value if the instructions stated to use a torque wrench that has been verified to be correctly calibrated and accurate to the in/lb, but they do not.

I pour an entire 5qt jug of oil in the engine. It should be ok. I think there is a certain amount of flexibility in how much is ok.
After all the oil level sometimes goes down after a number of miles.

That's what I do, too. It puts it right in-between the marks.

Same here, I just dump in 5 quarts and call it good. I don't use a 5 qt jug but it's the same amount.

I'm a "fill to the top of the mark" kinda guy. :)

The exact amount would vary depending on a few things, but generally about 5 quarts, as others have mentioned. If this is your first oil change and you don't have any extra oil lying around, it might be a good idea to get an extra quart of oil in case you want to top up in the future (and for emergencies - I keep a quart in the trunk just in case).

You guys will confuse people. OP has 2.5T and Mazda says it’s 5.1 quarts for oil change quantity. But for 2.5L it’s 4.8 quarts for oil change quantity. Many 2.5L owners put in 5 quarts for convenience but it still below Full / Max mark by least ⅛ quart、 or ⅛ between Max / Full and Min / Add marks. Now you guys say using only 5 quarts for 2.5T which is 0.1 quart less than Mazda’s spec? Other 2.5T owners have been using 5.5 quarts for oil change which should bring up the oil level to the Max / Full mark.

One can measure the oil level hot or cold, whichever way you prefer. It’s been proven they won’t make too much difference.

I put in 5 qts in our 2.5T. I like to keep it just below the Max mark. Need to leave some space for OD. :)

But 5 quarts is less than Mazda’s oil change spec for the 2.5T:

And why there’re suggestions to “overfill” the 2.5L with 5 quarts when the specs say 4.8 quarts, but “under-fill” the 2.5T with 5 quarts when specs say 5.1 quarts? Double standards?

We all know Mazda’s specifications sometimes are way off. Its “approximate quantities” on fluid capacities are inconsistent at best and the engine oil quantities listed definitely are low if we consider the capacity is to the Max / Full mark of the dipstick like everybody else.

What is there to be confused about? Is 5.1 quarts not "about 5 quarts" as I stated, and as you highlighted in bold? The only confusion I'm aware of is your mention of the 2.5 NA, since both the OP and Ladd have 2.5T-equipped CX-5s, and the discussion has been regarding only that engine (until you brought up the 2.5 NA in this post).

As I have mentioned in my responses to you in particular, about filling the oil - it's personal preference, and the exact amount required depends on a lot of other factors (drain time, prefilling the oil filter, oil level preference, etc.). To account for all of those variances, an approximation of about 5 quarts is logical, with a suggestion to keep an extra quart of oil on hand to account for oil level preference.
