Oil classes?

[TygerTung]

In the haynes manuel for my honda CG110, it recomends the use of 10w40 class SE or SF, now is it alright to use for example class SJ? I have just rebuilt the motor about 500km ago, so it's just run in.

SJ is designed for cars 1997+ it says in this magizene, and SE is from 1971-1979, and SF is from 1980-1988. It's an old manuel from the 80's so maybe they didn't know about SJ oil then.

Surley a newer oil would be better right? Or should I use the older oil?

The dude at BNT said I had to use special motorbike oil or it causes the wet clutch to slip.... Is this true?

Cheers,

Sam

Sleep is for the weak!

It shouldnt really matter what oil you put in the newer the better in my theroy, which is already flawed, I see no problem myself.
