Gearbox and Diff oil [NC]

Hi, I currently own a MX5 NC 2011. I have seen some workshops which provide mineral gearbox oil. Would like to know if its recommended to use mineral or synthetic. I drive my car daily. Thanks

  1. My model of MX-5 is: 2011 MX5 NC
  2. I’m based near: West Midlands
  3. I’m looking for technical help or recommendations on: Gearbox and diff oil

The NC is very sensitive to gearbox oil. I believe there is a Castrol and Redline oil that’s good, I use Motul, massively improved cold shifting
