ok this talk has gone on to long..... oil height has absolutly no effect on the fork "ramping up". The oil in the lowers does nothing more than provide lubrication. Also, the forks use 50ml or cc not mm. You can run more or you can run less and the fork would feel the same, as long as the bushings are lubed up.

50ml / cc in each leg (milliliters and cubic centimeters are the same)

cool. Are you sure the ramp up deal is a myth? because it makes sense because if there is too much oil in the fork the seals will blow out. At least thats what a bionicon sales rep. explained to me. You work for FOX?

since the publication of the 2007 manual they have changed the spec to 50cc and suggest 10wt oil.

how come 10? would it last longer, or does it work better w/ the new damper or something? there werent really any notable changes to the fork in '07, so im wondering why they would change the oil weight

The 36/40 dampers have always used 10wt oil. The lowers used to use 7wt for lubrication but no everything is 10wt. Not 100% sure of the reason...it just is.

Next year with the Kashima coat there is a new specific lubrication fluid for the lowers that is supposed to feel amazing.

Fox recommends 10wt. RED oil and 10wt. GREEN oil, at $25 per quart there has to be a cheaper option. Can I just run Maxima Lubricants 55901 Fork Oil 10 Wt. in both damper and stanchion baths? It's $7 vs $50, is there a significant difference?

just run whatever 10wt you can find, it's not that important

You only need to use 50mL of 10wt oil into each stanchion tube, and you should use float fluid to lather the foam oil rings up nicely. Also lightly at the bushings below where the oil rings sit.

Here is a link to the service manuals for all their products. http://www.ridefox.com/fox_tech_center/owners_manuals/010/eng/index.html
Just select the 2010 Fox 40 and it tells you everything
