What type of oil in dampers?

[H8NSKPAUL]

Hi guys,

As some of you know I am in the process of converting a standard set of suspension legs into coilovers. I have got stuck & need help with identitying the type of oil that I need to put in the leg? what viscosity to use? I am sure this is crucial to the performance of the damper.

Any help is greatly apreciated.

Many thanks,
Hans.
