Comparative Oil Weights Table

15 years ago

Buying the right oil for your bike is very important as it can effect performance and the amount of wear-and-tear your bike receives. So what oil should you use in your suspension? Most suspension units use approximately a 5Wt (SAE). But, due to the international SAE standard being so loose, one oil company’s 5Wt can be the same viscosity as another’s 7.5Wt.

Here’s a really nerdy table that uses the much tighter Centistoke (Cst) testing scale, so we can compare brands with accuracy. Want to know more about oils, suspension components and your options? Check out www.teknikmotorsport.com
