LSPI is not an issue with the 2.5 Turbo MPI/GDI. If you don't want to use Mobil 1 AFE 0W-30, then you can use any API SP 5W-30 motor oil. If you're going to drive it hard, then Castrol EDGE 0W-40 is a good choice, so are Quaker State Euro LX 0W-30, if you can find it, or Quaker State Euro 5W-40. As long as it's API-approved motor oil in the correct service category, you can use it. The correct service category means that you'll have to use a motor oil approved for gasoline engines.
I inquired at my local Hyundai dealer, and they use 5W-30 in the 2.5 Turbo MPI/GDI motors. They don't have 0W-30, and they're not even trying to get it. Hyundai doesn't have specific approvals or requirements, and their internal service manuals show motor oils up to 20W-50 for these engines. If you want to beat yourself up over this, go right ahead. In our 2.5 MPI/GDO (non-Turbo), I use Castrol EDGE EP 0W-20 because it's MB229.71 approved. If I had a 2.5 Turbo, I'd use Castrol EDGE 0W-40 to add protection. Turbocharged engines tend to cook the oil, and over time thin ILSAC oils will varnish the engine. Have you seen the inside of an EcoBoost engine that ran 5W-20/30 all its life? It looks terrible.
