There are some here with far more than that. I’m at 189,000 and the engine is running fine. It does burn oil and if I have the time I might do a partial rebuild (replace piston rings and rod and crank bearings), but it’s been reliable.

 

My three Hyundai’s have 2.4 L port injected engines. The 2010 Santa Fe with 120,000 miles and 2010 Tucson with 74,000 miles just got an oil change with 1 qt of Marvel Mystery oil.

Result of driving with 1 qt Marvel Mystery oil, 500 miles prior to engine oil/filter change. (These are subjective observations, wife and girls told me to clean my ear, and I hearing things.)

1). Less valve noise
2). Remove plugs, bore-scoped, less or no carbon build up.
3) Open oil fill plug, engine looks very clean aluminum, no sludge or carbon.
4). Remove vacuum line, bore-scoped intake, very clean, very little or no carbon on intake valves.
5). Changed to latest API SP / ILSAC 6A 5W-30 engine oil, Walmart SuperTech $15 and Costco Kirkland. $13 for 5 qts.
5). Compression test 178-179 psi before, 183-185 psi after, gained 5 psi in compression, most likely freed piston rings.

 

@rjsilva how much oil does it burn? I think mine burns a bit but haven't pin pointed an exact amount yet.

 

Maybe a quart every 500-1000 miles, depending on how it’s driven.

 

My '01 5sp will burn/leak a quart about every 1500 miles... it burns a little but leaks a little too. My delivery job will have it idling for an extra 5 minutes, 7 times a night, but it's on schedule to top over 400,000 miles (640,000kmn) before February 14th. Original engine/transmission.

 

 

Do not tell my 2003 engine about this "expectancy", please. It work pretty well, do not burn any oil, still have original catalytic converter and have more than 212 thousand miles on the odometer My buddy have 2007 Elantra (same engine) with more than 260 000 miles on it (but his car burn some oil, to be honest). Proper and regular maintenance with quality oils, filters, belts etc. - and your engine would last much longer than that.

 

I have a 2011 with 145,000 miles. It hasn't had an easy life and I can't really see it going much past 200,000. With reasonable maintenance and an easy driver I can see them exceeding 300,000 miles.

 

@MR1Kingsbury not bad. And really 1500 isn't bad. Just a quart between oil changes. Just gotta keep up with it.

@Oleg S. I am beginning to think that the expectancy is based off of normal maintenance under normal conditions before the engine starts becoming less efficient (or a large issue occurs).
Let's be honest most of us on here care for our cars better than most. And from what i have seen (from Facebook groups) that this expectancy seems to be fairly accurate.

 

Also gained 1-2 MPG city and highway. City cold/short drives gained the most 2 MPG. 2010 Tucson getting 23-25 city. Previously got 21-22 MPG city.

 

@RAYMUND155 lol how does any of that relate to the thread?

 

I should include 2013-2014 Hyundai Elantra got 1 million miles on original engine/transmission. She currently have over 1.1 million miles on her Elantra. Please go watch 1 million mile Hyundai on YouTube, Hyundai did not believe her, until they discovered it was serviced by a Hyundai dealership and they verified it was original engine transmission. That Dealership service many “Hot-Shot Drivers” who put more than 500,000 miles on their Hyundais. That Hyundai dealership also offer 20 yrs/200,000 mile drive train warranty.

My post is meaning full because maintenance is critical to engine/transmission longevity. The new engine oil API SP / ILSAC 6A is a game-changer. Using Top-Tier gas (with detergent) and following Hyundai/Kia service bulletin to use Chevron Techron with full tank of gas at oil/filter change to keep fuel pump, regulator and injectors clean and reduce carbon/sludge build-up, increase longevity.

 

I'm glad got some more mileage to look forward too. My elantra is a 2002 GLS auto and its is just rolled over on 176,200 miles and until recently we havent done pretty much anything maintenance wise to it other than oil changes, filters and every once in a while brake pads. So far this thing has been a trooper being left in a field for 1.5 years because the shift solenoids went out. Replaced the solenoids and it drove from Tennessee to Florida and has been driving around town since July.

 

it IS time to replace the timing belt... Normally a 60,000 mile maintenance item, if it fails while the engine is running it will be VERY costly to repair... and in fact will total a car over 12 years old.

 

Good to know that I'm not alone. I also was skeptical about this "million in 5 year". 24/7 delivery vehicle with different drivers? Maybe... Personal vehicle with single driver(ever for delivery work)? No way.... Math is pretty simple.

 

Apparently it's true.

This Woman Drove Her Elantra a Million Miles So Hyundai Gave Her a New One

What's even crazier is that she apparently achieved the milestone in just five years.

For once ol' Ray isn't spewing utter nonsense.

 

The NEW API SP / ILSAC GF6A, is a game changer if the 7 news tests results suggest,

Previous oils have lost 9.5%-12.6% in ASTM Volitility test % loss 1 hr @ 250C. In a 5 qt engine that’s 1/2 qt in 1 hr at 250C. (Source PQIA Tested Oil Data), much higher Zinc caused O2 sensor shorting and Cat getting fouled. These lead to LSPI - Low Speed Pre-Ignition (detonation).

 

1 million Kilometers is very possible. vs 1 million miles.

 

The lady drove 1 million miles in a 2013-14 Elantra. 1,609,344 Kilometers on original engine and transmission.

 

I have faith and trust in Elantra as much, in fact more the the rest, but 200,000 miles per year is not believable. Sorry, if the story on the internet says its true but I do not believe.... Every service interval would have to be like a race car pit stop, getting the work done in minutes instead of days that is normal for dealerships..... Then to drive 600+ miles a day for 300 days a year by one person is not only illegal in US and AU but is downright not conceivable. OK, so the speed limit is 70mph... Average speed cannot be more than 60, assuming 1) stops for fuel every 5 hours, stops for traffic control, slows for traffic, tire failure. stop for an oil change twice a month, stops for rehydration, or dehydration.. I am not convinced... Not in 5 years... Maybe 5 years and 360 days. or maybe 2 or 3 full time drivers to swap out every tankful. But not 4500 miles/week, every week, every month, for 60 months. I would need more evidence....

 

Come on, mr. MR1Kingsbury. We should not be so selfish and must respect other opinions, even if they are illogical and implausible.

Mister RAYMUND155 (with his neighbor’s cars) already put shame on us.

Yes, 600 mile per day is a lot. Yes, 4500 miles per week sounds crazy. Yes, most bodyshop’s and dealer service departments work from 8 am to 5 pm (well, some of them from 9 to 6) and work only 5 days per week. Yes, “part’s delivery” job there in US assume many stops, city driving with speed limits, traffic etc. etc. Yes, Australia use kilometers instead of miles, and (accordingly to my buddy from Australia) common speed limit is 50 km/h (31 mile per hour) for city streets and 100 km/h (62 miles per hour) on highways (with some exceptions, of course).

However, what we know about Australia? What if this lady (with all my respect) is the only single person in Australia and delivering part to all body shops and dealers on whole continent? Maybe their body shops/parts department work 24/7 all year around? Maybe this fancy grille guard on her Elantra made her invisible to police radars? Who knows?

Australia is unique country. They not only drive on the wrong side of the road, they also walk upside down there!

Oh, sorry mr. RAYMUND155 – if you one of these people who believe in flat Earth, just discard my last sentence…

 

I live in NW USA. In 20 minutes you can go from Sea-level to 6,000 ft Alpental ski slopes. Trust me the Earth is not flat. From the top of Mt. Rainer (Paradise n Crystal Mt. Ski Resort) you can see the curvature of the earth.

Update. Finished performing 2nd oil change on 3 cars with API SP ILSAC GF6A. The full synthetic oil were from Costco Kirkland 5w-20 and Walmart Supertech 5w-30. The oil filter was Hyundai with new Al crush washer.

Observations and Tech.
The cold weather performance on my vehicles have noticeably improved, Faster cold starts, less initial knocking or vibration at cold idle, smoother cold weather running, better observed MPG at cold weather neighborhood driving, and smoother engine on 650 mile trip over the Cascade Mountains. PQIA test report show these oils have much lower viscosity at cold crank test, -30, protecting engines during cold start. I change my oils/filters between 3K-4K, the oils are much cleaner. I borescope the Al engines. They are still bright Al to no sludge or carbon deposit.

 

I've done some research and found numerous places claiming that the Beta 1 and Beta 2 (2.0L) has a life expectancy of about 300,000km (~186,000mi).

https://www.motorreviewer.com/engine.php?engine_id=63

While some sources such as: G4GR - двигатель Хендай 1.6 литра | Otoba.ru claims even less at 250,000km (155,000mi).

Finally a screenshot from Wikipedia:
View attachment 454119

My Beta 1 has currently 177,xxx miles and I keep up well with maintenance and I've always been told/heard.that these 4-cylinder were very reliable. But I guess everybody has a different perspective of reliability...

 

Hello EricRaptorMan, I ended up checking with my friend, whose Uncle had a Beta 2 powered i30 he drove to engine failure (rod through the block).
I thought the engine had died at about 400,000 km or so but the friend said it was up around 700,000 km (about 440,000 miles) when the engine finally cried enough.
Just to give some perspective from actual cars out on the road.

 

I've read in a couple of places that for the 2.0l Beta II, "Adjustment of valve backlash is required every 90,000 km."

I've taken my 2010 Elantra Touring to the dealership for years and no one every said anything about doing stuff like this. At 335000km (mostly highway) it's a little noisy before it warms up, and loses about 500ml of oil between changes (8000km), but otherwise runs like new!

 

I have 2009 elantra gl sedan g4gc 325k km 5 speed was leaking a bit of oil but fixed leak from valve covers still going Strong sometimes I drive a like a race car driver a few times a week and get 38 mpg when I puppy.. it's been on the road since new from February 2009 to this day of 2024 December and still going every day it's seen every winter with salted roads in Ontario canada and barely any rust there Just a little surface rust.
On the passenger side but i'm fixing that it's not even right through it has a 1 inch above the rear tire n tiny bit underneath good car also I still need to do the valve adjustment. The dealer never did it once just like Comment above me I don't Understand why don't they don't follow the There are maintenance intervals where it gets to a hundred thousand k or 60000m
