Whatman filters-.22 vs .45 does it matter??

[hammertime30]

I'm looking at a different brand filter at .22um....the most common seems to be .45um....Do you guys think it matters when filtering oil or do you think .22um would be difficult to push the oil through?? Has anyone used the .22um filters??

22 is water
45 is oil

You can get oil through a 22 if you have a the patience but I wouldn't do it unless it's been through the 45 first.
The 45 is enough though
