theres a whole big mess regarding shock oils and 'weight'. it requires a bit of reading, but basically wt is a very inconsistant means of measuring the viscosity of the oil. every manufacturer who uses wt for silicone shock oil has their own scale, and they are in some cases quite a bit different from manufacturer to manufacturer. Losi's 30 and Associated's 30 and Ultimate Racing's 30 will all have truely different viscosities.
The true measure of viscosity for silicone shock oil is cST, or Centistrokes. some manufacturers like kyosho and x-ray use centistrokes for their viscosity measurements. for some reason, though, they are using incorrect terms on their bottles, like CPS or CTS.
For the most accurate readings, a rheometre is used to measure the true cST of shock oil. The following link has conversion tables for some of the more popular oils with testing that was performed independantly using a properly calibrated rheometre.

Read through it and you will have a better understanding of whats going on. This webpage is what prompted me to gather all my old mixed oils and sell them so that I could get a complete set of oils from one manufacturer, allowing me to make changes with known values.

I also understand that associated is labeling their bottles of oil with both cST and W values:
