how much difference is there between 7wt and 7.5? My fox ones say 7 but i’ve got a bottle of 7.5 rock oil stuff. I’ve no idea how the fork il weight scale works so not sure if a .5 difference is significant or not!

Also do oils generally mix, (ie will the rock oil stuff mix ok with the fox stuff left in the forks)?

Thanks

You’ll not notice a difference. I think they mix OK.

You could get two different brands of 7wt and there could be a huge difference. The different makes will probably make more difference than the 0.5 on the label.

Chuck it in, if it feels wrong, swap it for something else.
