So, is it OK just to use cheaper car oil then?

oil change
 

:confused1:well that opened up a few ideas but when it comes to the oil grade/type i have read somewhere (cant remember where!) that if you use an oil with too many additives as in fully synthetic oil it can make your clutch slip ?? anyone had any expierence of this ?

If your engine is in reasonable condition you should use a motorcycle specific oil of the correct viscosity .I'd avoid car oils .
A lot of the VStrom guys use Shell Rotella non synthetic [diesel oil ]15/40 with very good results .It does not have friction modifiers and will be fine in transmissions as well .

I use fullsynthetic 5W40 oil from www.louis.de - Motorrad & Freizeit

Cheap, and seems fine. someties in the summermonths i change it to a 10W50 allso fullsynthetic.

Mine is an '03 and uses no oil what so ever.

If it burns oil, just use a thicker one, imo theres no need to go "down" in grade.

Get a 15w50 er something like that.
