Chainsaw bar oil works great also

castor cleans up real easy with denatured alcohol or simple green

I like to "slow the flow" with around 25% STP

I guess I could slow the flow a little more,,, but a 1/16" hole in my shaft log seems to work out pretty good for me.
As Daniel's recommendation, I would like to try the BIO chain oil.

This is the oiler system I like to use. That is a 3cc syringe (most pharmacies carry them) cut down to about a cc and a half. Drill and tap the collar 10-32 and run a 10-32 die over the nipple on the syringe then trim it to length. Fits nicely under the pipe and I add oil from a small bottle just before I fire it up. About a cc is plenty and you don't have to worry about all that oil dribbling into the hull if you are dead in the water. I have boats not run since October and they are still dripping oil at the prop end.
