This is my uoa from earlier this year. About 5k miles after this the shortblock got replaced at hyundai. I use to work at a hyundai dealership, but I was surprised to see this one fail at such a low mileage. Currently, the car has PP 5w-20. I am considering switching to either 5w-30 M1 EP or PP Euro L.
2019 Hyundai Tucson 2.0 GDI, 5,750 OCI PP 5w-20. Engine failed 5k later.

I dont want to talk smack about blackstone but
that oil is very thin.. and their fuel % is not to be trusted its inferred not directly tested.
100k warranty protects from engine issues if you trade in before 10/100
main reason I felt ok with the "IVT (cvt)" on the 2020 elantra.

Elantra is available with a 2.0 NA port injected atkinson cycle engine

Are you going to do one since you've had the block replaced? On those engines, 5w-30 all the way.
Even with the fuel you can see that viscosity remained within grade. Oil grade won't fix poor engineering.
I’ve come to the point where I don’t believe much at all regarding a Blackstone analysis. Viscosity nor flashpoint.
As to using a 30-grade, increased MOFT is not a bad thing.

it was before the new block.
Exactly my thoughts. You can also change the oil/fluid all you want, but if there is a flaw in the engine design or build, it's only a matter of time before failure.
I also don't think this can be used as a knock against Blackstone. Engines fail for any number of reasons, and not all of those produce wear metals that would flag Blackstone or any other UOAs.
5W30 for this Hyundai. The End.
Ya. IMO a UOA is more likely to provide a false negative rather than a false positive due to their inherent limitations
I will do one when I switch to 5w-30.
Just put in the P.P. 5w-20 ( S.P. , GF-6A ) along with a FRAM Titanium FS988 ( w/ wire mesh ) in the '18 Accent 1.6 Ltr. with G.D.I. . Since new it gets the smell of gas when checking oil level . The post by O.C. takes the edge off 
. Usually change oil and filter hovering around 5,000 miles .

Is it a T-GDI engine by any chance? What does Owners Manual say for recommended oil viscosity?
I thought it was a turbo'd engine, no? If that's the case, run xW-30 or xW-40 oil in it.

The 2L in the Tucson is not turbocharged.
How did it fail?

Not addressing the specifics of this engine failure, the Nu 2.0 GDi also had issues with engine failure. Not as common as the 2.4 or 2.0T Thetall, but still possible.
Viscosity may help with dilution but not build issues with some of these 2010-19 engines.

I'm pretty sure it was the connecting rod bearings.
At the dealership, we had sooo many pallets of blown engines. Hopefully, Hyundai fixed their problems with the new smartstream engines. I no longer work for Hyundai so I am out of the loop.
