No alternative oil is appropriate for Ohlins forks or shocks. You must use Ohlins 1309 and the fork oil is set by oil height, not volume.
What you have done is likely add too much oil to one or both of the forks, and it is limiting the stroke. Or it could be that the oil you used has a thicker viscosity (5W cannot be compared across brands) and it's limiting the compression stroke.
Drain the forks, refill with Ohlins 1309, and set the final oil height measured from the top of the outer tube with the outer tube fully down and spring NOT installed. 160mm is a safe place to start.
