Hello,
I have a 2016 Hyundai Elantra with 145k miles on it. I am original owner. Never had any problems with the car before. I was on a road trip from Utah to Alabama and back. On the way back home to Utah, when we pulled over to get some food engine just shut down. No check engine light, low oil, hot temp whatsoever. Engine started right away but then it happened again. Only while rolling on low speed (parking lot). When I checked oil, dip stick didn’t show anything. Luckily I was close to the store where I could buy more oil. I poured 1 quart, started engine, let it run for a minute and then checked oil level. Dip stick still didn’t show anything. I bought three more quarts and kept pouring gradually. It took two and a half quarts until dip stick showed max level. Engine takes 4.2 quarts according to manual.
There was no leak underneath the car, no black smoke behind the car.
We hit the road again and checked oil level after 2 hours - it was still showing max. Checked oil level at each stop, every 4-5 hours and was showing max all the time.
Can someone tell me what could have happened? What could have happened to the engine? Is there a risk that it’s damaged?
It's either leaking or burning, there are no other choices. When this happened when is the last time the oil level was checked? Many Hyundai engines are notorious for oil burning and other internal problems.
Of course with the oil level that low there is always the possibility of internal engine damage but if it's not making bad noises or displaying other obvious symptoms of serious trouble it should be OK for now.
oil level was checked/ oil was changed about 10k mikes before that happened.
That's way too long between oil changes which will cause the engine to wear prematurely.
About all you can do now is keep an eye on it and don't go more than 5K miles between oil and filter changes. When you change the oil check for signs of metal particles and debris in the oil. Aside from that and maybe doing a compression check you'd need to tear down the engine to determine the extent of damage and wear.
just saying that changing oil every 5000 miles is not a thing in my opinion.
5,000 mile interval is definitely a "thing".
The longest manufacturer recommended interval I've seen is 7,500 miles (12,000 km), and that's only under the most theoretically ideal conditions. at 20,000 miles the oil is sludging up, and you're significantly shortening the life of the engine. at 35,000 you're just waiting for the engine to seize any time.
And this is all assuming you have a perfectly made engine, which seldom happens these days.

if you're here then you're a fan of Scotty, a mechanic of 50+ years. So listen to him. (7:52)

Thank you for your answer Chuck.
oil level was checked/ oil was changed about 10k mikes before that happened. I use 20k miles oil for vehicles with high mileage. I heated it’s ok until most of it is highway mileage which in my case it’s about 90% highway mileage.
That day engine sound little different. But I was never expecting oil to be that low.
I know that people in USA change oil every 5k miles. Same vehicles in Europe change oil every 15k kms. That’s why I was going to change my oil after 10-12k miles. Some vehicles in Europe are required to change oil every 60k kms according to manual.
If you want your engine to last change oil and filter every 5K miles. 60kms? Not sure what this is in real miles, but there are plenty of videos on youtube showing sludged up engines where oil changes have been neglected for a long time. As Scotty says, oil is cheap and engines are expensive. It's that simple.
Well currently my Wife's 2016 Elantra in in the shop for random engine stalling and when restarted had almost no power when the gas petal was floored, but let it sit or try several starts and stops and it will go almost to normal.
The Dealer (I bought an extended 100k/10 year extended bumper to bumper warranty otherwise would fix myself) first replaced 2 dead coils (we have been complaining about 1 year for low engine power issues, they always said "could not reproduce"), but issue still happened, now they replaced the crank shaft sensor saying it had abnormal readings. My dealer stated to my that the 2016 Elantra were having a lot of crank shaft sensors failing, but there was no recall.
hope that helps
60k kms=60000 kms= 37500 miles.
just saying that changing oil every 5000 miles is not a thing in my opinion. Again, Europe changes oil every 10000 miles and those vehicles go for 200000 miles and more no problem
what’s your guys opinion about high mileage/ extended performance oil?
