Please explain what you mean by better????
10 Micron will filter better but 20 may have a higher flow rate depending on size.
If the filter is large enough to flow enough oil then 10 micron would filter finer particles.
Check the flow rate on both filters that info should be available.
Hello Polly, Bart is exactly right...
A filter that is fine enough to remove small particulates will be of little value if it will not have sufficient flow rate to satisfy the need...
