I own a 2019 Kia Stinger GT2 with the 3.3tt gdi engine. Kia originally gave a wide range of oil viscosity recommendations for my engine (5w30, 5w40, 10w30, 15w40 and 20w50) in June of 2018 they released a TSB narrowing the recommendations to only 5w30 and 10w30. Can anyone give a reason for this? The 2.0T engine can still use the heavier oils. Why remove them for the 3.3tt?
Now I'm at 40k miles and starting to notice some oil consumption. Currently I'm using Pennzoil platinum euro 5w40. I'm thinking about stepping up to 15w40 or 20w50. Thoughts?
