2019 Hyundai Tucson 2.0 GDI, 5,750 OCI PP 5w-20. Engine failed 5k later.

they didn’t learn to avoid these Korean pieces of broken turds after the very FIRST engine failure???

They didn’t learn after the second engine failure and thought that maybe 3rd time’s the charm and hoped it wouldn’t BLOW UP?!?!

I recently did valve covers and a leaky oil cooler housing on an 09 Santa Fe… What a terrible vehicle to work on. Every other bolt was a “*** were they thinking when they designed this”, moment.

That is a poorly maintained engine.

Ya
I don't think they take care of their vehicles very well....

Never tried M1 0W40 or QS Euro 5W40 (yet) in my 2017 Hyundai 2.4L GDI engine . Max OCI was 5K miles / 6 months , now I’m in that 3.5K to 4K mile / 6 month OCI range with M1 5W30 EP or Valvoline Advanced 5W30 and high efficiency oil filter (Fram Ultra) . Top Tier Shell or Chevron regular grade seems to run fine in the 2.4L GDI (although premium grade seems to offer better power / response) .

I've used both. It's the M-1 that works better inside those Hyunkia four cylinder engines. I'm getting a sewing machine sound using Amsoil currently in the cold weather . When I used the QS 40w prior in 80-90 degree weather, my engine sounded like an old Royal manual typewriter journalist pounding on the typewriter keys.

Lordy-Lordy What would that Kia sounded like, had I reversed the application and used the QS in the winter?.... shaking a shoe box full of marbles? Sorry, I reminded myself why I quit using QS in 2004. So I tried it again in 2023 and will wait another 20 years to try it again.

Wait -never mind. I'll either be in my 90s and senile then, or I'll be driving a hydrogen-powered vehicle. I follow member Accent Abuser. I do believe / recall that he quit using QS also, immediately following the end of his vehicle warranty at 100k.

Our Hyunkia engines prefer Mobil-1 over QS. They like the Valvoline you used many times prior. I quit Valvoline for political reasons. But if you are OK with their new ownership, I suggest you move back to Valvoline, or go to Mobil-1.

Just my opinion and how different oils fare with my Hyunkia products. If your engine(s) need 40w, they will let you know. Doing a trial run is always a good idea. Accent Abuser is a smart Accent oil shopper. He has the opportunity to abuse, but doesn't really.
