Make sure you've got a big flat drain pan. There's a lot of oil in those suckers!
You'll need a cup wrench to get the filter housing off and then tightened, although I've never found one that works for me, and use a strap wrench to get it off (protecting the side of the filter housing) and just tighten the new one by hand.
Works for me; no leaks.
You need a new crush ring for under the drain plug. Do you have the proper 8mm Allen wrench for the drain plug? I replaced my stripped aluminum stock plug with the LN Eng magnetic plug.
Make sure you let it drain thoroughly. I jack my car up on one side to get access, but when it's draining I let it down.
There's a whole big debate on oil, and it has steered me away from Mobil1. I ran it for 4 years, but my last fill (after flushing) was with Castrol Syntec 5W-40. I would use Syntec 10W-40, but we can't get it in Canada. Apparently any 30W is too light.
Don't forget to cut open your old filter element and check for debris!!
