mixing different weight hydraulic fluid

[FoxCPM]

If I mix a quart of hydraulic fluid 46 with quart of grade 80 would that give me a new grade of 63 or these numbers have nothing to do with averages?

I need weight 68, and the common ones are 46 and 80

Thanks!

Looks like Google would be a better friend to you than I can be now. I have no clue.

Same here I don't think it works like that though.
