Employees car. She has 104k miles on it. Regular maintenance by a nationwide tire chain. Complains of excessive oil consumption. I changed the PCV valve as that was suggested. It was using a quart every 2 weeks of local driving. No smoke or oil in tail pipe. Runs great. Not a drop underneath or on the ground.

How many miles is "2 weeks of local driving"? What type and viscosity is the oil being used?

You can't dismiss engine internals, like rings or valve seals, just because it runs great and there is no obvious smoke or oil in the exhaust. Have you browsed some Hyundai-specific websites to see if this oil burn is a common problem?

Is this car new to her, or is it a problem that popped up suddenly?

PS: knowing the engine type may help us guess/research better...

Oil Consumption is a big issue with these cars and she will need to stop every 1000 miles at an oil change place and have them check and top off until time to change, if she runs it to the oil change interval it will be out. Unfortunately she will be paying about $10 every 1000 miles, at least she won't even need to get out of the car. Ford has also had a few vehicles that did the same thing burn a quart every 1000 to 1500 miles, totally bogus manufactures can get away with this stuff!
Lots of blog talk about it.

Have her take it to the dealer. She'll get a new engine after they confirm oil consumption.

She drives 250 miles a week. Pennzoil high mileage 5-20 synthetic . She bought the car at 60K and has gotten progressively worse.

And you say this because of some info you know about? or they should just do the right thing? Good luck with getting a dealer to replace an engine at 100k miles.

Alas, I think 500 miles/quart is considered to be the minimal standard for "normal" by many manufacturers.

I did a quick browse, and see that some 2.0L Hyundai engines were recalled due to poor heat-treat of oil-control rings. However, those are for 2019 and later, and for a specific type of 2.0L engine. It is sure worth contacting Hyundai, this engine may be a candidate for free replacement; but don't count on it...

Now for some background info, ignore it if it tends to confuse the issue:
I am well-familiar with a similar issue with the Saturn 1.9L engine (1991-2002 S-series). The pistons for those engines were made with no holes behind the oil rings for oil to drain away. As a consequence, excess oil remaining there tends to cook, make a residue, and then make the oil rings stick and not function. The result is high oil consumption similar to what is reported for the Hyundai. These (Saturn) engines can run fine like that, no obvious smoking, and pass Calif. emissions. The good news for us Saturn folks is that the cylinder bores are "well lubed", so wear on the block/pistons/compression rings is usually negligible.

Good luck and hope she can get something done by Hyundai! Other than putting $10 in every month.
