2018 Hyundai excessive oil consumption

[laurieja1]

I just joined this forum so if this post is not what this website is for please delete. Thank you

I have a 2018 Hyundai that suddenly at 72,000 miles has started using excessive oil. I took it in for an oil change and after just 2,000 miles the oil light came on. I took it back to the place that had changed the oil and they told me it has no oil in it. They told me that Hyundai had a recall for this, so I took it to the dealership and they told me that my model was not included in the recall. They said that they could do some sort of flush out to see if that fixed it but that is was going to coast me $1,000. I didn't and don't have the money for that, they told me there was nothing else they could do. Now I drive around, a single female having to check my oil every week carrying around a jug of oil adding as needed. Is there anyone that can tell me what I should do?

Are you the original owner?

Odd that it suddenly started using oil, rather than gradually started using more.

Clogged PCV? Stuck oil control rings. I wonder what the recall addresses?

Or is this a service bulletin, may want an opinion from another dealer.

I would think would be covered under the 10 year/100,000mile powertrain warranty.

No I bought it used with 27,000 miles on it.

It could be as simple as the oil brand and viscosity that burns readily.
If it were me, I'd continue topping off with 10w-30 oil till 4K miles in after last oil change and do another oil change with 10w-30 or 5w-30 oil and keep monitoring oil level weekly. If oil burning isn't improving then contact dealer and/or call Hyundai Corp to request warranty engine replacement.

Going from full to "no oil in it" in 2000 miles isn't due to the brand.

You say used but did you buy it as a certified pre owned or not and just used. If you don't know for sure go through your documents. If it does have a certified pre owned warranty you should still have the 10 year 100k mile powertrain warranty and if you do then you can pressure the dealer into doing a free oil consumption test to where if it fails the test then repairs or replacement is free. And that awful stealership is an absolute con artist for actually trying to charge you a thousand bucks for what is likely a $20 can of liqui moly engine flush which I know they won't guarantee will fix the problem so that you can't ask for a refund when it does jack so you'd be out a whole grand. I'd suggest going to a different dealer entirely. That one you went to is rotted out to nothing.

Most likely not. We don't know whether oil level was at top mark right after last oil change, what oil change sched the car was on, what engine, what maintenance etc. Could be PCV, they are cheap and quick to replace.

 

[Propflux01]

It is the 1.8L engine. Usually not a problem with them, but if you just bought it used and outright, you are past the 5-year 60K transferred warranty. If, as was described earlier, you bought it Certified Pre-Owned from a Hyundai dealer, then the 10Y/100K warranty is still in effect.

All HyunKia's from this era use oil. Gave my '17 Soul to my daughter. Check the dipstick twice weekly I said. Did she? No ran it dry. At least you're not like the 18 year old girl who posted "What does the teapot light mean?" on a Soul FB page. Still have nightmares about that.

Mine didn't use any. Ever. Traded it with 136K on it.

Going low on oil and having the oil pressure light turn on is very bad and probably did irreversible wear damage and only further exacerbated oil consumption. Yes, it sounds harsh but Hyundai/Kia require meticulous oil changes just to compensate for their design, material and production weaknesses. Direct injection and weak piston ring tension are contributing factors that u have no control.

If the engine never went low on oil and only consumed oil, u could do an oil cocktail- Valvoline Restore & Protect + HPL 30 EC. It requires 500 mi dipstick monitoring. There is anecdotal evidence that it slowed oil consumption by cleaning the piston oil control rings. The caveat is the cylinder bores were not damaged or had excessive wear.

Was it full to begin with? And what oil light came on? Some hyundais have an oil level sensor. No oil in it could mean below the dipstick which is half a quart below minimum.

Hyundai's are know for carbon sticking the oil control rings down, which increases oil consumption. Valvoline Restore and Protect is a newer oil that is designed to free up stuck rings like this. It's not overly expensive, so you have nothing to loose by trying it. They say it takes about 4 oil changes before you will see results. If it were me, I'd use 5W-30 Restore and Protect, and change it at 5000 mile intervals. As you mentioned, carry a jug with you and check every time you fill up the gas tank. With time, you will learn how often you really need to check the oil (likely less likely). And hopefully, after some good miles, the oil consumption will decrease.

Get a Hyundai dealer (or an independent shop for less $$) to do piston soak procedure.
Here's how Kia describes it:

What model of Hyundai? How often do you get the oil change done? I'm assuming, based on your original comment, that you take it some place to get the oil changed?

Without the model, we don't know what engine. While many of Hyundai's recent engines are known for acute excessive oil consumption, some are not. For example, if you have the 2.0L Nu MPI engine, that's not an engine where excessive oil consumption is common. However unlikely, it's probably worth replacing the PCV and seeing if that at least slows the consumption. If you have a 2.4L GDI, 1.6 GDI, or even the 2.0 Nu GDI, those are known for oil consumption and the problem is, unfortunately, likely a lot worse than a bad PCV.

Okay sure. But it wasn't because the OP used a particular brand. This consumption (if accurate) is way beyond brand difference.
