Hey Everyone,
I asked the Mag1 support team about using the following product:
http://mag1.com/ProductDetails.aspx?id=feb26b17-c445-4631-ac06-5f688312182f (Euro Spec 5W-40)
Their response was interesting.
"You should not use our Mag 1 European formula in your 2013 Hyundai Sonata. It will void the warranty as it is the improper fluid. My vehicle guidebook states you need a motor oil meeting API SM certified by the American Petroleum Institute (starburst symbol). Our Mag 1 European formula does not have the "starburst" symbol, only the API "donut" as it is formulated for European vehicles. For more information regarding this topic please see this link : http://www.api.org/certifications/engineoil/categories/upload/motor_oil_guide_2010_120210.pdf
Regarding viscosity grade for temperatures you should follow your owner's manual.
Thank you for your question."
I don't think a 5W-40/0W-40 exists that carries the starburst symbol??
This is what Hyundai said about using that grade.

"The reason SAE 5W40 is also recommended for the Sonata and Genesis Coupe is because their engine management systems differ from the Santa Fe Sport Turbo and are calibrated more aggresively to obtain the extra Horsepower they possess."
I'm probably over thinking all of this, I honestly don't see the harm in trying 5W-40. Like I said before, I'm just experimenting to see how it does against 5W-30. I will not use it long term if UOA results yield poor results.
Has anyone received mixed recommendations like this before? By the way the manual even allows for API SL if SM isn't available. Not sure if that makes much of a difference.
-Thanks
