I just bought 2013 Mazdaspeed 3 and while perusing the owners manual I found that Mazda now endorses Castrol as their preferred lubricant.
Wow, a little concerned about that as the engine in these things is referred to as the little volcano. In my last Speed I used Pennzoil Platinum with great results, but back in '08 Mazda didn't really endorse any particular oil, just required the use of a high quality 5w-30.
Has something changed with Castrol oils that I am not aware of? I would imagine they used Castrol products in the validation of the engine but that oil doesn't get much respect here so I am leery of using it. IMHO there are so many better synthetic oils that I could use (including my old stand by Pennzoil Platinum).
Any thoughts on this? Any oil recommendations?
