Hyundai 2.4 oil for replacement engine

[Urshurak776]

The Kia Rio isn't burning any oil after a Berryman's piston soak. I am now just doing a once a year change as my son doesn't drive much.

My other sons 2019 Hyundai Santa Fe with the Theta II burns a little oil, but not much. Maybe 1/2 a quart in 4,000 miles. Doing 4K OCI in that with Valvoline Restore and Protect (on the third interval now.) The Valvoline Restore and Protect has made no difference at all. None. Car has around 65K.

I don't think the oil brand makes a lick of difference on whether or not these engines will blow. From dollar store API SP whatever to Amsoil . HPL. If it's gonna blow, oil brand isn't gonna matter.

Run cheap supertech and it should last 150k +
Run Mobil 1 and likely same engine life with 3500 changes

148 000 on the Hyundai Sonata and still kicking.

Sonata sold at 150,000 to my daughter so I will be able to update . It’s tough when you sell it for $1 lol Good for her not so good for me . Purchased a new Kia Sportage hybrid. 1500 miles and awesome so far .

You too? ;-) I just sold my 2011 2.4 Sonata Limited for $1 to a nephew in college. My engine was replaced at 119,000 and it is going strong at 161,000.

We just got our Hyundai Sonata back with a new (rebuilt) long block. The car is in great shape with 145,000 miles, and I will be using it to drive ~1,600 -2,000 miles a month, mostly long trips, so I'm thinking about keeping it for a while as a commuter.

My plan is to use Hyundai filter, even though they didn't question the aftermarket filters I used in the past or when I took it in for a blown engine, see post.

So now I have to decide what oil I want to try to keep this one from drinking oil like the old one... I'm thinking 3,500 miles OCI with a 5W30. I ran a lot of Mobil in the last one, but some 6500 OCI.

Mobil EP 5w30, Mobil 1 ESP 5w30, Valvoline RP 5w30, something else?

I was always curious do they give another New car 100,000 mile ten-year warranty

As they keep building these engines are they making changes so that they are reliable? Surely they must have some idea of how to make engines that don't drink oil so badly. I know there is more to it than just this. It just seems to me that they should make engines that can be counted on to go the distance.

Yes get rid of the low tension rings.

Yes , New cars still get the 10 year , 100000 mile power train warranty and 5 year 60 k bumper to bumper.

Hyundai doesn't change, they put their head in the sand. This has been going on for 14 years. Many are "hoping" their new engines are designed better. The newer engines have Multi port and direct injected injectors. But that is not the issue "metallurgy choice" with engine is the problem. Chrysler and Mitsubishi use the same designed engines, BUT with a much better metallurgy choice. They don't have the engine issue any where near Hyundai/Kia. My personally hypothesis is the higher ups have their own engine building companies, and use it as a "legal" way to imbecile money through doing the 200,000'sssssss of engines. A "high" gearhead high school kid could fix Hyundi/Kia's engine problem with "let's build our engines with more robust metal choices and a couple design changes to increase robustness. Problem solved. It IS that easy. But Hyundai/Kia =Head in the sand" churning out rebuilt engine, after rebuilt engine, after rebuilt engine THEN the second engine fails and then the third engine fails, there are a lot of those. I have heard of Hyundai putting in 4 engines.

Hyundai/Kia are in the top 3 list of engines that get jammed rings, be it oil rings and in my case jammed top rings that lead to excessive fuel dilution vs oil rings that lead to oil consumption. I think the default oil should be Valvoline Restore and Protect from day one , till the death of the car/truck.

Forget 20W oil in H/K engines as well - after the factory fill and one UOA using Quaker State Ultimate Durability 5W20 (oil was essentially toast at 4K miles) it’s been 30W the rest of the way in H/K engines for me . The wife’s Seltos 2.0L MPI engine is the first in the fleet to get Valvoline Restore and Protect 5W30 with the Sonata 2.4L Theta II and Sorento 3.3L vehicles next in line to receive Valvoline Restore and Protect 5W30 . If I didn’t have some moderate oil burning in the Sonata and Sorento GDI engines I would have been happy with the Mobil 1 30W ESP EP oils I had been running for a max OCI of 4K miles / 6 months in all three H/K engines . *If after 4 OCI’s of Valvoline Restore and Protect I do not see refuced oil burning in the GDI engines (as some users have noted) then it’s back to using Mobil 1 ESP 0w30 for my fleet of H/K engines to ensure high enough MOFT to help offset engine wear from soft metallurgy of key engine parts (i.e. rod bearings) .
