Here's a procedure that works for me. Unfortunately, my vehicle usage almost always requires a full lube job at each oil change so I've only been able to enjoy doing this twice.

This won't work if the oil filter is on too tight unless you're a gorilla. If the filter is on not more than 3/4 turns and, ideally, has been twisted back slightly in the reverse direction, most should be able to use this method. I like to do it when the filter is slightly warm and the engine cooling down, but I'm not sure at what temperature the filter is easiest to turn.

Loosen:Put a cloth down to catch drip (see 3rd pic). Stand facing against the front part of the driver's side wheel well. I'm 5' 9" and require a short step stool for this. Reach in (see pic) with the left hand and apply torque to the filter. It probably won't move but keep applying torque. Rest if necessary but eventually the filter should start to budge. When it gets much easier to turn, don't remove it but, instead, move into the remove/install position.

Remove/install: Stand facing against the front of the vehicle where the horns are. If you needed a step stool in the first position you'll need it here, too. Reach in with the right hand and get a good feel for the angle/location of the filter. You may even want to unthread it and then re-start the threads to solidify the feel of installation angle. When it's ready to be removed, let it swivel in your fingers to a thread up position to minimize spillage. (Some people have mentioned using a bag at this step. If you can get that to work for you, it will cut down on mess. When I tried it, I dropped the filter so I'm sticking with the pivot method. I've had the skids off a couple of months later and the oil mess is barley detectable.) Carefully pull it out being mindful not to catch it on something and drop it. Wipe your hands and grab the new filter. With the feel of the angle/location of the old filter fresh in your mind, the new one should thread on fairly easily. Turn 3/4 turns after seating and then turn it slightly in the reverse direction to make the next filter change easier.

The downside to this method is having a small oil drip from the skid plate for a few hours.

Good post. I still remove my skid plate. Adds 10 min total (5 off and 5 on). I don't even jack the truck. Are dude's having issues getting their skids off?

Also, Fumuto valve on the drain is a life saver!

Getting them off is no problem. If they're bent up, getting them back on can be a pain.

I've done this two more times since posting the thread. After getting the procedure down, it's really quick and easy now.

Totally thread reviving here, but I'm having an absolute ***** of a time getting my filter loosened from the top. One of the bolts on my skid plate is rusted solid and I rounded the head before I thought to hit it with PBLaster (the other one came right off even though it looked about as rusted), so I'm going in through the top.

Which direction do you turn it? Logic dictates that it should be left when facing the filter, which would mean that when you're facing the truck and turning the filter, it would be directly back towards you--i.e., turn the filter towards the front of the truck to loosen it.

Is that correct? I've never had this much trouble getting a filter off. Effing dealerships.

Yes, left when facing. Counterclockwise. Same rotation as the wheel rolling forward.

If you're attempting to remove someone else's installation it might well be impossible.

I should probably add that I abandoned this method long ago. It's nice to know how to do it, but it's usefulness is pretty limited especially when weighed against the potential for making a mess.

For future just remember as your looking directly at the end of a oil filter or a bolt its counter clockwise as stated or "Lefty Loosey Righty Tighty"......lol
Very rare on cars anymore but they do still use left handed bolt patterns but I myself have never seen it on regular maintenance items like filters.
My old 69 Dodge Superbee had left hand threads on drivers side lug nuts but I changed them to rights like everyone does...

fyi: Heres why they put left thread nuts on mopars...lol
