After reading loads of stuff on the net which is mostly years out of date, it seams that the main differance between car and bike oil is the fact that most but not all unit construction bikes use the engine oil to lube the gear box. Pre-unit construction (seperate gearbox and engine sump) and many unit construction bikes from the 1950's onwards used an EP oil (extreme presure) for the gears.
It's the shear effect that breaks the oil down? and shortens the effective life of the oil, now there is the point if with modern semi and synthetic oils if it has any adverse effect if the oil is changed every 6,000 miles.
A few years when I got a new works van the FIRST service was at (from what I can remember) 26,000 miles or one year. A motorbike would be on its 5th service at that rate? if it did that milage.
So should you use bike oil..........YES.........will it make a differance ..........that's up to you?
