MOPED ARMY

I'd say whenever it starts to look bad... is there a filter on it?

Or, whenever you feel like it, I'd probably do it at least twice a year.

Bil, I have a PC50.I change the oil whenever it starts to turn brown.On these peds an oil capacity is 750ml or 2/3 of a bottle.For the cost of a 1 litre of oil,frequent change are not going to kill you. Oh and by the way,why are you yelling?

when you use caps you are speaking loudly; when you use lower case, you are being normal. sh-h-h.

PC50 oil change every 1,000 miles in clean conditions. If hot, dusty, cold conditions, change more often. If sluggish, change it; it will seem like a tuneup.
