When you say 'engine oil', do you mean the two-stroke oil which you put in the tank behind the side panel (or is it under the seat?), or the oil which goes in the gearbox/clutch?
If you mean the 2-t oil, then get the finest synthetic stuff you can find. If it's for the gearbox, any old bike 10/30 or 10/40 will do.
If all else fails, you could always read the manual, of course.....
