Ossa Mar, What Oil Does It Need ?

Featured Replies

As above, what oil is it needed for the engine / box. ?

I just use a 10--40 grade engine oil from a motor spares shop I think about 900cc I found if I used a light gear oil the clutch slipped.

 

my ossa is a gripper I think the mar uses a bit more oil?

I've experimented with a lot of oils to get the best from my race bikes over the years and used them in my trials bikes. On the 'modern' 1960's two strokes (obviously not in the 'unit' four strokes, I found Caterpillar TDTO to give the best results. No clutch slip and no wear.

I know a lot of lads who use ATF in theirs.

Modern cheap 10/40 as used by bisby is as good as anything and far better than the best and most expensive stuff we used back in the day....

If anybody wants a litre or two of Cat' TDTO to try, pop in and I'll give you some.
