Thread 'Skyactiv 2.5L - Oil Capacity'

Apr 5, 2020

So unlike the 2.0L Skactiv engine, the Skyactiv 2.5L takes a bit more than what the manual states to hit the top hole on the dipstick. PimTac correctly told me this a few weeks ago.

Per the Mazda manual, the 2.5L engine takes exactly 4.8qts with a filter change. However, 4.8qts only brings the oil up to slightly above half when hot. When cold it is about 1/2 of the dipstick. I'm not sure why this is the case. Are they accounting for fuel dilution?

The correct way to check the oil in this car is to bring the engine up to operating temperature, the re-check after the car has been off for...

Thread '2020 CX5 oil capacity discrepancy'

Dec 22, 2023

Did my first oil change on my new to me 2020 Mazda CX5 Grand Touring. 2.5 non-turbo.

Manual and websites say 4.8 qts. Why did it take 5.5 qts. to bring the oil to the full mark on the dipstick?

I used ramps, so the front up on an incline. While the oil and filter was draining I jacked up the rear to level the car out. Nothing addition seemed to drain out while raising the rear to level.

I have been working on cars for years and aware of all the stuff, like car level, wait until all oil returns to oil pan etc.

Just surprised it took .7 qts. more than the book calls for to get to the...

Thread 'Mazda CX5 Dipstick'

May 7, 2016

I just replaced the factory fill on the wife's 2016 CX5. It has the 2.5L engine that calls for 4.8 qts of 0w20.

After replacing it, I can't get a reading on the dipstick - even after letting it sit all night. I checked underneath and it is as dry as a bone. I always use a new crush washer, and this time was no exception. So I am not really concerned since the oil could not have gone anywhere. It is just hiding somewhere...

Anyone else with a CX5 have trouble reading oil on the dipstick?

Thread 'Favorite Oil in Sky Active 2.5L engine ?'

May 12, 2022

Considering a new Mazda CX-5 and a main reason is the great reviews of the Skyactive 2.5L engine . It looks like it will run well on either the specified 0W20 or 5W30 ... Your preference and experiences in a synthetic oil for the Skyactive 2.5L ?

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

May 17, 2021

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 ?

I dump 5 quarts with a filter swap in my 2017, 2.5 Mazda 3 and slam the hood.

Love this approach.. thats probably what Im going to do now based on all this info, which will bring it just slightly above the middle mark of the two dots, but not quite to F. Thanks!

This is why I'm not a fan of 10-minute oil changes. You'd be lucky if they put a new washer on it, if they even put one back on at all.

While not a Mazda, I just recently changed the oil in my sister-in-law's "New to her" 2021 Subaru Forester. It was supposedly serviced at the dealer. It has a little over 60k on it, and the crush washer that I removed from the drain plug still had black paint on the edges. It had never been changed out in 4-5 years, 60k miles.

I totally agree. Ive had overfills, overtightened lug nuts, wrong oil altogether.. Never again, not even a dealership. Always do it myself, which is why I am so appreciative of this forum and all of you for your help.

Yeah, the drain plug on that Subie was tight! I had to use a 12” ratchet and put all I had into it to break it loose. It shouldn’t take anywhere near that much force to break a drain plug loose.
I was hoping it wasn’t buggered up when it came out.

I use 5 quarts with 2.5L engine.

Jug of oil is perfect for these Skyactiv engines.

I noticed that more oil drained out of my parents' CX-5 with the Skyactiv G 2.5 NA than my old 2.5 MZR which is supposed to have a 5.3 qt oil change volume vs 4.8 of the Skyactiv. I highly doubt the 4.8 will get you to the max mark as others have mentioned.

I mean, sure, if you're good with your oil at the half-way mark. Mazda says it's fine. I'm just too OCD, I like to roll at the Full mark. I would be bothered endlessly to leave it in the middle, even though I know it's fine.

YMMV

Dipsticks aren't precision measuring tools. Most of our irrigation motors don't have them, and we have to eyeball a sight gauge, lol.

I think I’m with you on this. I measure 4.5L and have not much left. The whole 5 quarts still won’t reach the full mark. I have to think full to the mark is still not overfilled. You think?

 

[CleanSump]

A couple of ounces isn't going to make or break the universe.
SD's Honda Accord says 4.4 qts. I dump in 4.5 and done.
Our BMW says 6.9 qts. Dump in 7 and done.
I don't let the bottles sit on the valve cover to drain every last drop. They get drained in the lawnmower dribblings bottle. That accounts for some of the minor few ounces.

I've had 7 mazda's with skyactiv 2.5 liter motors and I can say each one differed, albeit not significantly, with regards to the amount of oil req'd for a full fill per the dip stick!
