Core RC Shock Oils: How do the viscosity 'grades' compare to other brands?

[Origineelreclamebord]

Hi everyone,

I recently bought some Diff Oil from Core RC, and I am quite content with the stuff - The price isn't bad, the bottles close well/work nicely, it used cSt ratings, which I am used to because I currently use Tamiya (not TRF, Tamiya) shock oils...

However, the stock of shock oil is down to nearly zero on the more important oils. The Tamiya oils are only for sale in sets - and fate has it, 300, 400 and 500 oils are the ones I use the most (which are in two different sets)... So, I'm considering to switch to Core RC.

I'm just wondering, how do the Core RC viscosity grades compare to other oils (Tamiya, AE, Losi?) - I found the image below and I'm concerned the 400 oil from Core RC is actually 40wt (which is way too thick for me).
