does the castrol meet the mazda mv spec? (which i think is renamed mercon v but im not sure)
i think the transmission is a ford 4f27e but it is called a mazda fn4a-el.
the vehicle is a 2007 mazda 5.
I don't think mazda MV is the same as Mercon V, but I did 3 drain and fills on my 06 mazda 3 with Castrol Multi Vehicle when my car had about 20k miles (at that time I thought MV was short for Mercon V), then at 40k miles I did one more drain and fill. Right now I have 50k miles and the transmission shofts really smooth, I will probably be changing again at arund 60k miles along with the fillter (I still have the factory one).
Based on that I think Mercon V is OK.
