oil viscousity

What is the correct oil grade for an fd3? Am I right in thinking 15/40?  Just thought I should check before changing it.
Thank you please.

most use 10:40 if it\'s the castrol mineral oil stuff........Not to say that 15 might be wrong but as i understand it.
What slippy stuff you using? & what sort of abuse you planning on giving it?

Si mate, I don\'t know what is in it at the mo as my mech changed it last (I couldn\'t be arsed).  Moderate abuse no tracks or nout!  Too scared of hurting her!  There is some nasty armcos on race tracks.  Some on roads too I believe.

Thinking castrol GTX.  Its mineral isnt it?
