2012 Mazda 3 SkyActiv Oil change question
I was reading through the forums and it is time for first oil change. I bought the car with 31K. I have no idea what was used before. Is any fully synthetic 0-20w probably okay, or should I really get the Mazda oil with Moly? I read where it was a bit thinner and better for starting. However, right now I don't change my own oil. The place I go has Mobile 1, Castrol, and something for GM motors they use called Quantum (meets some GM standards).
The Mazda dealer I called just uses Castrol GTX. So I'm thinking it is probably okay to use any of my previous listings. What do the experts think? Or do they disagree as well?
