Chainsaw bar oil will stick to the chain a little better.[ it works very well on non O ring type chains ]
But it might not be what you want in some circumstances as road muck will stick to it as well .
Sometimes you will want to overoil the chain in order to clean it .
Gearbox oil is a good compromise .
Blessed are the cracked, for they let in the light. - Spike Milligan
