Between those two I would go with Castrol 5W30...I like Mobil 1 5w30 better than Castrol though...that's my opinion.

+1 for Mobil 1 for top pick, Castrol would be my next choice.

I thought it was posted here a list of approved oil and both Castrol and Mobil have to be 0W-30?

Anyway I used Catrol 0W-30 when I did mine couple weeks ago.
