There is a modified piston ring on later models. I have seen a few of these using 3 1/2 litres in 15000kms. It is not and upgradeable part though, and a modified engine is fitted in place.
35000 km
I too noticed, 2020
You must be reffering to this
However, this issue started from 25000 km. Spark plugs do not show any sign of oil consumption. But,turbo to intercooler hose got some oil deposites. Dealer is suspecting a turbo failure.
Did you observe it on the modified one or the earlier one. Mine is 2018 manufactured done only 35000 km. I am really disapointing on mitsubishi quality.
Do you recommend me to use 5W30, which is recommended for Japan. Presently I am using 0w20.

The earlier version suffers with oil consumption issues. Here in Australia we use 5w30 only in this engine
Many thanks for the reply. Does the 5W30 reduce or completely stop oil consumption issue?
I am wondering why Mitsubishi did not recall this faulty powertrain and did the necessary replacement.

No it does not. But for here, it is what we use..
Not all cars have the problem for some reason. And some use more oil than others.
We have replaced 3 engines and have another 4 being monitored for oil comsumption. But we see around 30 of these a week with no problems

It is really strange why some only getting the problem, may be construction material issue of a series of vehicles.
Did you guys dismantle an engine and checked what has happened, is it clogged oil scraper rings? in mine, spark plugs do not show any sign of oil burning, no oil stains!!! Here dealer has got no clue and they are suspecting turbo failure by noting some oil residue in the compression side hoses. But I believe this is a false diagnosis.

We did not strip the engine down. All the checks we did over the time frame of a few months were enough for Mitsubishi Australia to condemn the motor.
It is unusual that only a few of them are really bad, and other not so bad. The new ones are great though, I have a 22MY and it doesnt use a drop of oil

It could be a group of vehicles produced in a particular duration, mine is 2018 March. It would be interesting to tear it down and see where the problem is? I am wondering it could be a faulty turbocharger since no evidence of oil passing through piston rings.
I am using the vehicle for short trips, but the oil change was done timely "either within 6 months" or within 5000 km. Always used Valvoline 0W20 fully synthetic and genuine oil filter.

Thank goodness for this forum. Seems like my 2018 Eclipse Cross SE is suffering the same issue. Here's my history with the vehicle.
Bought it in the Spring of 2019 and haven't had any issues until a few months ago.(end of August 2022) The car is only used for around town driving. I.E. Work, school, shopping, occasional in-state vacations, etc I am normally on top of scheduling routine maintenance at my local dealership, (oil changes, tires, brakes, fluids, etc) however this one specific time I was approximately 1,000 miles passed my oil change. That faithful Monday (August 22, 2022) I had all intents to immediately schedule one with my dealership after realizing how far over I was, but then it happened. I got the "Low Oil Pressure" warning message in my dash cluster. So before you knew it was Friday and I hadn't made the appointment with my dealership. (because life happens and sometimes you get busy with work/kids) I got hit the the Low Oil Pressure warning message as I was approaching a red light.When I came to a complete stop at the intersection the car just died. (Stalled) Luckily I was able to crank the engine again and continue to my destination. (Pick my kid up from school) I immediately called the dealership and told them the whole story and they didn't have any appointments until the following week, but recommended I get the oil changed right away. Took it to one of those instant oil change places and they were like, "yeah you shouldn't have been doing any driving after that low oil pressure light came on the first time." There was no oil whatsoever on the dipstick. So got a full synthetic oil change (like the manufacture recommends) and to stop back in when I put on another 3,000 miles. I also had scheduled an appointment with my local dealership to do other maintenance with the car the following week. Asked them to look into any possible oil leaks due to the recent occurrence I just experienced. Dealership said no leaks detected. I.E. Gaskets, hoses, etc Fast forward to today.
Today was the day my car had just over 3,000 miles from the last time I was at the instant oil change place about 4 months ago and upon their inspection of the oil dipstick today, it was bone dry again! Luck would have it though that I had an appointment already scheduled with my dealership this afternoon! I.E inspection/emissions, new battery, and brakes. Told them I wanted a more through and in-depth look at this problem because there's no way in hell this car should be consuming that much oil in between the last oil change 3,000 miles ago. (Side note all prior oil changes were occurring approximately every 5,000 miles with full synthetic oil at the dealership per the dealership recommendation.) Well tonight as I was writing writing this message I went to check the vehicles Warranty and Maintenance manual to verify if the dealerships recommendation matched. To my surprised it DID NOT. It states every 3,750 miles (6,00km) or every 3 months. (Whichever one comes first.) I kinda wished I skipped telling the dealership about stopping at the instant oil change place today and want to see if they would have told me there was no oil on the dipstick or not. Now per their request on my service paperwork they provided me today it states, "Customer needs to come back every 1,000 miles for documentation. Do not add or change oil until test is done." I am personally going to do my own weekly video documentation of the oil level (via the dip stick) and drive the vehicle until I approach the required 1,000 miles. However lets say I get into the 2nd month of driving it, (and I'm nowhere near the 1,000 mile mark) but I notice the engine oil dip stick is bone dry again....I'm going to carry on and drive the vehicle like dealership recommended without "adding/changing the oil until test is done." At that point all the liability falls on the dealership because I (the consumer) followed their recommendation. TBH it shouldn't be the consumers job to even do what I'm doing on my own after reporting the issue to the dealership. But now I'm weary of the whole situation and doing this as my own CYA (cover my ass) in case I need to present evidence in the event they try to say it's my fault. Even though it's not.
Send good car vibes that my EC survives these 1,000 mile oil consumption monitoring test.

What was the frequency you had the customers bring in their Eclipse Cross's for oil consumption test/checks? I.E. Certain number of miles/months (Whichever comes first?)
And forgive me beacsuee I'm not familir with the expression "condemn the motor", but what does that mean?

They were coming in 3 monthly for checking and topping up by us only.. All amounts added were recorded for evidence.
Condemn, in this case is as per dictionary definition "sentence (someone) to a particular punishment, especially death"
The engine is deemed unrepairable, so it shall not be reused

How many 3 month checkups/oil top ups were required by your customers before Mitsubishi Australia made the decision to condem the 3 engines you replaced?
You also mentioned you have 4 additional Eclipse Cross's being monitored for oil comsumption. Just curious if they're all the same year and how far along they are in the testing. Do you predict they will suffer the same fate as the last 3?

The testing was over about 2-3 years. When a car comes in for its first oil change at 15000 kms is when we notice a low level. That is when the testing starts. Owners have never complained of this, probably because they never check the oil themselves. All the vehicles are in the 2018-2020 production era, and are YA designated (Eclipse cross first generation). It is very likely these other units will require repair, as the oil loss is too much to be reasonable.

For clarifications sake, based upon your previous message response it took 2-3 years to conduct/conclude testing (customers bringing in their vehicles every 3 months for oil top ups/logging oil consumption) before Mitsubishi Australia made the decision to condemn the 3 engines? Then you replaced all of those customers engines via the power train warranty.
Do you happen to have any official documentation from your dealership that shows the recommended oil change timeframe for a 2018 Eclipse Cross? I.E. So many miles/months. (Whichever comes first.)

Servicing information is available on the mitsubishi Australia website.
Here we do not have powertrain warranty. These vehicles are given full vehicle waranty for between 5 to 10 years depending on year of purchase.

Really I don't understand why Mitsubishi Motors investigate this matter and take corrective actions immediately. It is obvious that this is an issue arised from either faulty engine desige or spare part. Delaying the corrective action could lead to unncessory problems as clogging of Cat Convertor and sensor failures, by that time perhaps the warranty might be elapsed, giving trouble to customers. They should probe in to the real cause of the problem, is it a turbo leak or oil piston issue?. Apparently, as Dibby mentioned, even Mitsu Australia has not done an indepth analysis of what has gone wrong. My gut feeling is the cause could be the use of premitive single piece oil ring in ECs produced in 18 and 19. I recall, Honda Fit also suffered same issue some years back and Honda Motors accepted the fact of design failure and did corrective actions.
Seems Mitsubishi Motors is not such responsible company
