Break in oil consumption (2024 CX-5 Sig)

[propflux01]

Just a general question concerning oil use during break in. I know many engines use some oil the first few miles of a break in period. My 2024 sig is the first vehicle Ive ever owned that used any oil before the first interval during break in. That being said, how many of you all out there have had oil usage during the first 5000 miles? If so, when did it stop (or did it ever stop) using oil? Ive lost a half quart in 4500 miles, just curious how others’ experiences stacked up.

I've had 2 CX5s, a 2020 and a 2024 and neither have had any measureable oil consumption during break in or subsequent to break in.

Just a personal thing of mine in over 50 years of car ownership, but I never let the break in oil, (or whatever you want to call the oil that comes in a new car), get to the 5000 mile mark.
I've always done my first oil change quite early, and oil consumption has never been an issue with any vehicle I've owned.
I did the first oil change on my 2017 Mazda 6 at about 3,500 kms (2,100 miles).
I recently did my first oil change on my 2023 Stinger that I bought one year ago new. It has 2,500 kms on it (about 1,500 miles). That's just me though. Not everyone will agree, but that's OK.

From my experience the Turbo will lose some oil during the break-in period. It wasn't significant, maybe couple ounces to get it back to the full mark. Regular NA didn't seem to lose any but I changed the oil at 3,600 in the NA, around 4,800 in the Turbo. Just my observations.

is yours turbo or NA? how are you driving the car? aggressive? moderate? gentle?

It is a signature turbo. Normal driving. Up and down hills, but no hot rodding.

half a quart in 4500 miles is really nothing to worry about.

You can consider using thicker oil to slow down consumption. In fact, I would recommend it.

So long as you are not frequently or repeatedly going past half throttle during break in, your internals shouldn't be under any excessive stress.

You can expect your engine to be fully worn in after 3000 miles.

What is your current fuel economy?

Turbo engines can consume some oil. Go a bit thicker, like 5w40 and don't worry about it.

I know it's not bad, but the OCD in me isn't happy, considering this is the first car I've ever had use oil.

I am going to let Mazda dealer do the first 5K service, to get it "on the books" and probably do it myself for the rest of its life.

No, just normal driving. I think I've pushed it once or twice passing a car on a two-lane, but nothing over 3K and not long. Nothing I haven't ever had to do in any other new car I've had.

The current is between 26.8 to 29.7. At this moment it is 30.1

I was hoping to stay with the 5-30 but If I have to move up I guess I will.

Perhaps change the oil filter yourself or at some quick lube place before taking it into the dealer for its first service. Metal shavings will be in there from the break in process.

Have you had a turbo engine before? I've heard you can expect some consumption from them.

Again, it's really not anywhere enough to be a cause for concern, likely consumption occuring by high heat and shearing forces generated in the turbo itself.

Going a grade thicker is not at all any cause for concern and in this case would be helpful.

Yes. The Wife's car is turbo. Never has used a drop of oil since we bought it with 3 miles on it. I do all the changes with 5w-30.

Mine only has 400 miles left now before the 5K service, so already have it scheduled.

I drove over 1500 miles last week on an interstate trip. The oil level is down a bit on the dipstick, but still well over half way, so maybe it consumed 8-10 ounces. The oil will be changed in another thousand or two, so I won't top it up.
It might not use as much in cooler weather or on shorter trips at lower speeds, but I don't think this is excessive for possibly up to 30 hours of operation at highway speeds in 90 degree heat, and it seems many other newer cars are similar.

I would stay with the 5w30 until at least the warranty expires. Use what the manual says to use. If something happens in the future you wouldn't want Mazda denying a claim because they say you used the wrong grade oil.

Oil is fairly inexpensive, if the consumption continues at the current rate buy a gallon jug and top it off when needed.

Did you check the oil level when you took delivery? I know I didn't and it could of been low to begin with.

Yes, I've been keeping an eye on it since I got it. I had planned to stay with the 5w-30 if I could. My other vehicles use that as well, even the other turbo car.

Even if you occasionally did go over 3000RPM before the 3000mile break-in point, that would not have caused any accelerated internal wear.

Plus, your fuel economy was good. Unless someone else was a bit hard on the car (such as a test driver before you bought the car, someone you lent the vehicle to, etc.) caused some minor internal wear, sounds like there is some slight wear in one of the seals from the factory.

It's minor enough, that if you were to experiment with different oil weights, you could stop it all together.

It had 4 miles on it when purchased end of May. I'm hoping it just goes away on its own, hence if anyone else had this issue.

Yes, it certainly can, and likely will on its own. It did for me.

there is no need to go thicker than 5w-30 on the turbo

 

[Mazdiod2]

I think the Mazda 5w-30 is a regular mineral based oil, not synthetic.

 

[N7turbo]

I'm not sure. At 1,200 miles I drained 5.7 quarts. I know how much I put in, so I'll know in ~2 months when it's time for my next change.

 

[cxha]

Our 2020 GT used 1/2 quart, then nothing more in 20000 miles. The 2022 Signature turbo hasn’t used a drop in 14000 miles.
