Refilling suspension with oil

I have an old mountain bike which I'm taking apart, cleaning and fixing. I have taken the suspension apart and need to put new oil in it. According to the manual it requires:
Right Leg Top (Volume) cc/ml - 93
Oil Weight - 5
Right Leg Bottom (Volume) cc/ml - 10
Oil Weight - 15
Left Leg Top (Volume) cc/ml - x
Oil Weight - x
Left Leg Bottom (volume) cc/ml - 20
Oil Weight - 15
This is all new to me. Does it mean I need to get 5 weight oil and 15 weight oil, measure out 93ml of 5 weight and mix with 10ml of 15 weight then put these in right leg. and then just 20ml of 15 weight into left leg on it's own??

it should be clear from the manual, but it sounds as if the left leg has a single oil chamber and the right side has two separate ones, each needing a different grade of oil; if so, don't go mixing it up!

If my hunch is correct the 5W oil is for the damper, and the 15W oil is mostly just for lubrication of the internals.

cheers

93ml of 5w oil? Sounds like the fork may be a Rockshox fork, possibly a RS Dart? If so the 93ml of 5w will be for the damper (item #10) and the 15w at the bottom will be for lubrication, as Brucey says.
