Put this stuff in my Mk3 gearbox and it made it very stiff to change from cold, although shift is fine when car warmed up.
Get the impression from looking on the web this could be a real issue in winter (it's currently 25 centergrade)
This is undoubtably good oil, but don't think it suits the MX5 mk3 gearbox, this is GL5, whilst Mazda recommend GL4.
I have now put Castrol oil in of the same grade, so time will tell if it's an improvement.
