I am servicing my Fox forks and need some 10wt oil for the lowers. Just been to the Motorbike shop for some and F*** me they wanted £20 for a litre. I have some 15wt and some 5wt so was thinking of mixing the two to make 10wt but my brain cant work out what proportions I need of the two.

Is it as simple as a 50/50 mix :oops:

    Yep, 50/50! Assuming they are what they say, they can vary a bit in actual weight.

    Cheers Sonic I will get the syringes out. It is Stendec Crystal fork oil do you know if it is as rated on the bottle.

    Not sure - i think we have a chart in the FAQ.

    To be honest, for lube duties it doesn't make too much difference, the damper is more critical.

    I had a look in the Technical FAQs before but couldnt find anything unless its titled under something else. Its only for the lower leg lube its a FIT fork which I believe the damping oil is in a seperate chamber so should be okay.

    I've mixed that exact brand of oil, 5 and 15wt to make 10wt and it was a success. Damping is as it was prior to swapping the fluid.

    You shouldn't have a problem.

    All done and dusted got nice squelchy forks, now just need the weather to play nice so I can go and test them out.
