Genesis motor oil

[Genny46PM]

Does anyone know if the Genesis engine is pre-filled with synthetic motor oil at the point of assembly? I am now approaching 1,500 miles and contemplating whether I should get an oil changed with synthetic motor oil now rather than waiting until the recommended 7,500 miles.

I switched over to sythetic at 5000mi.

Comes non-synthetic. Switched to Mobil 1 0W-30 for the winter and just changed to Mobil 1 5W30 for Spring/Summer.

I used Mobil 1 5W-30 last summer, but will be running M1 0W-30 Advanced Fuel Economy year round going forward.

Do not use Castrol Syntec or Amsoil 0W-30, which is a European formula and not suited for the Genesis (or anything except German cars that specify it).

 

[Genny46PM]

Thank you!
Being in California, I will likely do the oil change with Mobil 1 5W-30 soon.

Why not use Castillo, that's the oil I've been using for years with all my vehicles

Because Walmart does not sell it, and a Google search of 'Castillo motor oil' does not seem to come back with even a single relevant hit.

Castrol makes several oils that meet the spec. for the Kia/Hyundia engines. Castrol GTX (API grp.II) petroleum based, Castrol Syntec & Syntec Blend (API grp.III) Hydrocracked/Hydrotreated petroleum based and Castrol Edge (API grp.IV) PAO based oil. Castrol Edge is very similar to the Amsoil products which is also a PAO based oil.
All of these oils are available in viscosities suitable for our engines.

Yes, I agree, but don't use Castrol Syntec 0W-30 or Amsoil 0W-30 European Formula oils in the Genesis, which have different specs than the Mobil 1 0W-30 Advanced Fuel Economy oil sold in the US. That is the point I was making.

There is a lot more to oil specifications than just the "stated" viscosity, which can be very misleading for synthetic oils.

Mark,
That is correct. American Kia/Hyundia owners should use 5w/20 or 5w/30 in their vehicles regardless of what brand or base oil they chose.

I slightly disagree, in that Mobil 1 0W-30 or 0W-20 (both called Advanced Fuel Economy by Mobil for the these viscosities sold in the US) are acceptable also in the Genesis.

But Amsoil 0W-30 and Castrol Syntec 0W-30 are different (in ways other than the viscosity rating) and are designed for German car oil specs (European ACEA: A3, B3, B4; VW 502 00, 505 00; MB 229.1, 229.3, 229.5; BMW LL-01). The Mobil 1 0W-30 AFE does not meet these German car specs (as do none of the 5W-20 oils that Hyundai specifies).

I fail to understand why anyone would want to use an oil that does not meet the spec. of the engine manufacturer. My Borrego's owners manual recommends 5w/20 or 5W/30 only. I'm not sure what is recommended on the Genesis. I would suspect the same.

The issue with the European Formula oils like Amsoil 0W-30, Castrol Syntec 0W-30, and Mobil 1 0W-40 is that the exceed the specs. Exceeding the specs is usually not a problem, but the European Formula oils don't work well in engines not designed to run them. Mobil 1 0W-30 Advanced Fuel Economy is fine in the Genesis. Oil specifications for synthetics are a little more complicated than for conventional oils.
