1) Thanks everybody for your responses!
2) I actually let the oil drain for quite some time because I spent a good 20 mins or more trying to get the filter off while the plug was removed.
3) So, you guys are saying I should:
1) Drain oil.
2) Replace filter with new one.
3) Replace oil plug.
4) Return oil to engine.
Basically, I have to drain the oil in order to replace the filter. This is correct?
Thanks again!
