I use one part Mobile One to 3 parts mineral spirits or Coleman Camp fuel. The selection of thinner is not critical. The idea is that the thinned oil easily penetrates the pivots, then the thinning agent evaporates leaving the oil behind.
After application, wipe the chain clean with a rag to remove any excess.
I have no idea what is in ProLink, or any other commercial chain lube, but this formula works very well, is long lasting, and is cheap.
