i was helping a friend clean up his bike for winter storage.. after the oil change he decided to give it a wash but forgot to replace the oil filler cap. hosed down the bike on one side but he came around the other side he noticed the oil filler cap was not in place.. from what i understand and saw, some water must have gone through that filler hole..not much though because hose was set on "mist".
- He wants to ride the bike to the gas station to fill it up. (gas)
- should he add a little bit of more oil and ride it anyway. the engine could use a little bit more of oil since he didn't put enough.
- should he just dispose the entire oil from the engine and do a fresh a oil change?

thanks guys
 
don't run it...not worth the risk...drain the oil out and put fresh stuff in...then go to the gas station and fill her up....then when you get back drain the oil and fill again and put away. that's my0.02's
 
For what's involved in doing an oil change - Change the oil. NOW. Don't start the engine or even crank it until you do that.

You don't know how much water has gotten in. Whatever has gotten in, is heavier than oil, will sink to the bottom of the pan ... where the oil pump pick-up is, i.e. there is a good chance that the water will get pumped into the main bearings, and water is not a good lubricant.

Engines deal with minor amounts of condensation easily, because the next time the engine gets to operating temperature, it boils off. But, a big slug of water in there is a whole different matter, and you don't know how much has gotten in.

Because water sinks to the bottom, it will also tend to be the first to come out of the drain plug. If you are careful, and you drain the oil into a CLEAN drain pan, you may be able to refill the engine with the same oil you drained out ... and if there is any visible water, just don't pour in that last little bit with the water in it.
 
thank you guys for your fast replies. i just advised to do what has been adviced on this forum.. glad i asked. thanks guys
 
You can add a little Seafoam to the fresh oil after the change and it will remove the last traces of water too. Read the can though, don't add too much.
 
Might even want to flush a little oil through once everything is done draining and before putting the plug back in and refilling, just to rinse out whatever might still be in there. Extra oil wasted is a lot cheaper than shop labour hours.
