Super easy to do.
Jack up the truck and support it with jack stands. If you've never done this, be careful.
Locate the oil drain plug. Be sure it is for the engine oil.
Get your catch pan under the truck and loosen the plug with the appropriately sized 6pt socket. Do not remove the plug with the socket. Once it is loose enough to do it by hand, take it out by hand and don't drop in in the pan. Set it aside to inspect and clean off before reinstallation.
While that is draining, identify the oil filter. Chances are the person who changed the oil before you tightened the crap out of it. You may need a filter wrench to get it off, you may be able to get it off by hand. Regardless, don't loosen it more than a turn before you put a pan under the drain lip located directly under the filter. Once the pan is there you can unscrew the filter all the way. Empty the filter into the pan and make sure the oring is still on the filter. if it isn't, just pull it off of the oil filter housing. Old filter and oring, discard. Rarely does the oring stick to the truck, haven't had that happen in many years.
While that is dripping I like to put the oil plug back in. Inspecting the plug for metal debris or torn washers before installing. Clean the area around the plug with a rag and install. Don't over tighten just make sure it isn't going to leak.
Once the oil filter area is done dripping wipe it all down with a rag. If you don't wipe it now you'll never get to it after the filter is on and it will drip in the garage or driveway.
Take the new filter and fill it half way with fresh clean oil. Take some on your finger and wipe the oring on that filter to lubricate it.
Screw it into the same place the last one just came from. You'll have to feel around with the filter to find the threads but be very gentle. You do not have to force the filter on and you don't want to cross thread this at all. You'll get a dozen turns out of it before it is tight. If it is tight right away, it's on crooked.
Once the filter is hand tight its done.
Open the hood.
Open the oil filler cap.
Take your time after 6qts because she will start to fill up on you. Do not overfill it. It's very easy to add more and very hard to take some out. Once you think it is full, using the dipstick to measure, put the dipstick back, put the oil cap back on and start the truck for a minute. Shut it down for a minute. This fills the oil filter with oil and leaving it off for a minute gets it out of the heads and into the pan. If it needs another 1/2 qt add it now.
Check it again in a day to make sure everything is good.
Just be careful under the truck man, that's one thing you're going to regret is it falling on you.
