Hey guys my 91 VN S2 has 475,000 kms with a ,untouched or rebuilt engine and original 5 speed gearbox and diff. but i don't know what type of oil i should be running. its currently running 20w 40 and its running good, but i was wondering if i could put a lighter oil in and if so will it wreak my engine. It has highway kms of about 250,000 kms and then was owned by a old man so the engine was never thrashed.
