Now that I own a 2022 KIA Soul and I've read through various posts here and elsewhere and I've watched a number of Youtube videos I'm opening up the discussion on choice of oil. Normally, I read the owner's manual and just follow it and that works well with my Lexus and Toyota. Since there seems to be more going on with the Hyundai/KIA engines than normal what is the collective's thoughts on choice oil and OCI? Owner's manual calls for 0W-20 GF-6/SN+/SP with an OCI of 8K miles or 5miles under severe conditions. I'm running Castrol Edge EP 0W20 in the other two vehicles.
