I'm trying to help you with your oil consumption issue, as I have some experience with the 2.4 GDI.
Three questions for you:
1) Did it come with the "increased capacity" oranged dipstick from the factory, or did you get that via a recall or service bulletin update?
2) What other lubricants did you run in the engine and did it always consume oil?
3) How many miles on the vehicle and when did it start to consume oil?
I'm trying to offer you a best guess why it's consuming oil, as the amount of oil it's consuming is not normal.
As for my 2017 Hyundai Santa Fe 3.3L, I ordered a quart of engine cleaner from HPL and I will run a full 5000 mile OCI with that. I know the engine is clean, however, I want to get out whatever little possible dirt is in it. I will also send an oil sample to OAI and see if there is any unusual amount of wear metals or fuel dilution.
E.g. - if you have one or more pistons scuffing the bore, that should show up in an oil analysis as an decent size increase in Aluminum. Someone who knows more than me about the subject please correct me. I know that @dnewton3
is highly skilled and experienced when it comes to organizing and interpreting UOA data.
if I'm right, then you should probably do the same. Unfortunately, I learned that with these Hyundai engines the viscosity or oil brand isn't exactly the solution to keeping them for a long time. Proper maintenance and keeping them clean is.
