Well I think that is a lesson learnt, I did not know that but think before I run it, I will drop the 5 litres out, hadn't bought the extra litre yet so apart from a 30 second run I haven't done anything with it. I can afford to buy some more oil, I cant really afford to buy a new gearbox so think I will play safe and not test it, just in case!
Lesson learnt is dont listen to the idiot in Halfrauds who told me it was for bikes and cars
See? This is why I asked, but was too late, thanks all.
Have had a read on the JASO and API standards and happy the Motul I have just ordered is the right stuff, thanks, it is MA2
