Excessive oil consumption

[HBMaGneT]

2023 Palisade that uses the same engine with 20k miles. No oil burned between 5k OCI. I use Shell Rotella T6 5W30 or 5W30 HM full synthetic during the summer. Kirkland 5W30 over the winter.

Interesting video on Valvoline's new Restore and Protect engine oil for those of you with engine oil consumption.

EDIT: Some positive Amazon reviews. I don't have oil consumption issue yet, but I'm considering restore and protect at 60k, 90k, 12k, etc.

It does not spec ACEA

2020 Kia Telluride 55k miles. Did 1st phase of oil consumption test. I returned it after 1000 miles and on invoice it said it was missing 2.7qt of oil only after 1000 miles.

On the second test now for another 1000 miles.

Symptom was wife would state it would shudder when going uphill or from a stop. I finally checked oil and it was bone dry. We did an oil change and after about 3k miles it was almost empty .. barely can see anything on dipstick... that is when we took it in for consumption test.

My 2020 Telluride has 62k miles and has received regular oil changes. It just recently started to feel like it was going to stall when I came to a stop. Shortly afterwards it started making a weird noise. No odors, no warning lights displayed. My husband decided to check the oil and it was literally dry. He had to add 4 quarts of oil before it even touched the dip stick. We have an appointment with the dealership in a week, but I’m afraid that they are going to blame this on not getting the vehicle serviced on a regular basis or that nothing is wrong with it. My biggest concern is the fact that the check engine light never came on which could have posed a serious risk to the vehicle or myself. I’d love to know if anyone has experienced similar issues.

Yes I have also

my 2020 telluride has 89541 on it and it uses 4.5 quarts of oil at 4200 miles and it is serviced every 5000 miles at the dealer.They tell me this is normal for this engine something is wrong.

Same here, if there is a "low oil" sensor, it never comes on. If there's a low oil pressure warning, I've never seen it. Last year within less than 5k miles after an oil change our Telluride started ticking, I checked the oil, bone dry. I put in 2.5 quarts before I could even see any oil whatsoever on the very tip of the dipstick. The next time we drove it, rod knock and the engine was dead.

I'm still waiting for Kia to recall this and reimburse us for the thousands of dollars we had to pay out of pocket for this. I have a feeling that'll never happen.

we will never buy another gdi engine again...the oil consumption is unacceptable...why even do an oil change

 

[Kao]

i am a new (<2500 miles) owner, so i have to ask: doesn't an "oil" light show on the dash to notify a low oil status?

Nope!!

There is the normal low-oil-pressure light. Other than that, the driver is not given information on oil level.

In my experience that kind of feature is uncommon, probably because the oil level can really only be checked when the engine is not running and there has been time for the oil to drain back down after the engine has run. My wife's Mini has such a system and it is a PITA to use, but the wizards at Mini have determined that the dipstick can be eliminated. The result is that she does not check the oil level as often as she should, like "never" unless I remind her.

the normal low oil pressure light doesn't work on the telluride so what's the point?...my subaru has low oil pressure and a low oil level lights...never seen the low pressure turn on but that's because the low level pops on first and i put a quart in

I dunno. The low oil pressure light in my Tellie seems to work just fine. The pressure sensors that I have seen and used are very simple mechanical devices wire directly to the light and just ground the sense wire when OP is below threshold. I have never had one fail, even on racing engines, but that doesn't say that they don't or can't.

Re Soobs, my last car was a WRX but I don't know whether it had a low-oil-level sensor in addition to the alarm pressure switch.

so your telluride has had low oil pressure and the light has come on before?...mine lights up when i put the car in accessory mode but i doubt it would work for it's actual purpose

Why do you doubt?

I don't have access to Tellie wiring diagrams, but my guess is that the Accessory Mode displays for alternator failure and low oil pressure are accurately reflecting the fact that the alternator is not putting out and the oil pressure is indeed zero. IMO, there would be no reason for these to be faked.

Since I check oil at reasonable intervals it is highly unlikely that I will ever see the oil pressure light when the Tellie engine is running. IIRC I have only seen that warning once, on a racing engine fresh off the dyno. I air-freighted the engine back to the builder and he rebuilt it again but never told me what the problem was. The metallic sheen in the oil told me that a bearing had failed but the warning light saved the engine. On the racing engines I used 20 or 30PSI switches; I don't remember which.

 

[Point37]

what i'm saying is no one here has ever said that the low oil pressure light popped on when the oil is almost all out of the engine...therefore whatever sensor is supposed to turn the light on does not work or is designed incorrectly...so other than seeing it turn on in accessory mode like below, it doesn't function/turn on when it's supposed to, so what good is having the light...just because it lights up when you start the car doesn't mean it functions properly

OP please put a poll on this thread asking if anyone has ever seen the low oil pressure light come on and how much oil was left when it did...probably won't happen since OP only has 1 post ever

That light has NEVER come on in my car to indicate low oil and I was down 5 quarts 6k miles after previous oil change. That’s the indicator light I wanted someone to show a picture of on here. Thank you for posting that.

i would imagine the light should come on by that point...the car takes a little under 7 quarts total...started a poll to see if anyone else has any input

Low Oil Pressure Light

has anyone had the low oil pressure light come on when you have low oil pressure, like it's supposed to?...not counting when you put the car in accessory mode like the below photo shows...also please share how much oil was left in the car when the light came on...i assume the dipstick will not...

WADR I think you're mixing up two concepts.

Concept #1: If the light works like every other one I've seen it will come on when oil pressure is near zero -- below its trigger threshold which may be something like 5 or 10PSI. IOW it means that for all practical purposes the engine is out of oil and should be shutdown immediately to prevent bearing damage. It might also trigger if a bearing has been damaged to the point where the clearance is so large that the oil pump cannot maintain pressure. Either way, the engine is done and you're likely to get a seized engine or rod through the side of the case if you keep going.

Concept #2: That the light is warning of low oil level. You seem to be expecting this and I don't think that's right. I don't think the light is intended to or is capable of doing this. So if you get the light you cannot expect to limp somewhere to top the oil back up. Maybe. Maybe not. Dirty Harry's famous line applies: "...you've got to ask yourself one question: 'Do I feel lucky?' Well, do you, punk?"

Now it is true that some cars do have a low oil level light (My RX-8 did IIRC) but Kia does not advertise this as being one of them. That's why they say: "Drive carefully to the nearest safe location and stop your vehicle."

exactly...under concept 1 when the low oil pressure light turns on the engine is most likely already damaged so it's pretty useless since the car was being run without sufficient oil cause they set the pressure at which the light turns on too low...maybe this can be fixed with a software update?...and under concept 2, no, i am not expecting it to light up cause a low oil level light doesn't exist on this car, but it should be added with the next redesign to prevent engine damage since the low oil pressure light is not going to prevent damage from happening

Ah.. we are moving forward.

Unfortunately for your theory, the engine oil pressure does not depend on the amount of oil in the engine. As long as the oil level is enough to cover the oil pump inlet, the pump outlet pressure will be unaffected by the total engine oil level. The outlet pressure is determined, roughly speaking, by the design of the pump, the temperature of the oil, and the bearing clearances. So pressure will stay in the design range until the pump inlet sees oil foam or no oil at all. Then it will head towards zero very quickly. The exact trigger pressure of the sensor makes little or no difference.

Re damage when the light comes on because of low oil level, that is mostly under control of the driver. Yes, there will almost certainly be damage. If he shuts down the engine quickly and is lucky, maybe only bearings will be damaged and the rebuild will be relatively cheap. If he missed the warning and the result is a broken rod and a hole in the case, that is not repairable.

2020 Telluride w/120k started burning oil like nuts around 95k. We've had the shuttering at the stoplight and seen some black exhaust from the tailpipe during heavy acceleration at different points. Yesterday, I added 5 quarts of oil to bring it back up to full. I'm not a car guy, can someone tell me where all of this oil is going? Also, do the newer models run the same engine and suffer from the same issue? I actually really like the car other than this one major issue.
