Notes:
- The viscosity index shows how well an oil retains its viscosity at different temperatures, so the higher the viscosity index the better. Redline has some impressive numbers, best prices I found are here.

- For some viscosities, Torco RFF oil is labeled almost double the weight of other brands, so pay attention to the actual viscosity and not the weight.

- Rockshox oil is actually repackaged Torco RFF, but with the weight on the label corrected.
