2 parts Dexron tranny fluid.
1 part 10w-40 syn oil.
1 part chain saw oil SAE 30, or STP or Slick50.
The chain saw oil has an additive that makes the oil stick to metal.
While on the oil... 10w as in 10w-40 is not SAE 10 weight. First the 40, the 40 is the SAE viscosity at 212F degrees. The 10w is an indexing number to compare oils with winter additives at 32F degrees... 5w is thinner than 10w is all it's telling you, it has nothing to do the the actual viscosity at 32 degrees... it's probably in the hundreds.
