Well, after installing the filter in the pvc line yesterday, finally had a chance to take the cobra for a run today. Was out for ~1.5hrs. When I got back I thought I would check the filter. Didn't know what to expect. When I opened the hood, I was surprised to see about 1/4 teaspoon of oil in the filter. :uh oh: Is this considered alot? Here's a pic of the amount.
