oil in my antifreeze

[Otus]

I was changing out the antifreeze, took off the radiator cap slid my drain pan under the bike and pulled the drain plug. After I got it all empty I slid the drain pan out from under the bike and there were a bunch of spots of oil floating in the antifreeze.  Then it hit me ( DUH!) I never wiped the pan out after I helped a friend do an oil change on his bike. Had an oh $#!+ moment there for a second but I got over it.

Stuff like that gets your full attention for awhile doesn't it.

But, what the heck, if oil really had been in the coolant it'll just slick it up and help it circulate more faster.
