In one gallon cans, ready to use, all castor oil, Plain bearing and ball bearing types. $20.00 per gallon plus shipping, USA only. For those who wish to mix their own, ether can be difficult to obtain (used in another hobby!). Try using THRUST starter fluid by GUNK sold at truck stops and intended for diesels. This contains 25% ether and the rest is mostly heptane but it seems to work.
Now a better alternative to THRUST may be JOHN DEERE (tractor supply) starter fluid which is reputed to contain 80% ether. I also have Amyl Nitrate in pints at $12.00 plus $6.00 shipping, USA only. 

A basic mix is equal parts by volume, ether/kerosene/oil.

A better mix is ether 3 parts, kerosene 3 parts, oil 2 parts by volume.

There are many variations for different purposes. My Diesel Diary goes into this in detail.
