This is for changing oil on the 2007 4Runner V6. I'm not sure if it's different on the bigger V8.
What you need:
socket wrench with 14mm socket
5.5 quarts of new oil
new oil filter
new crush washer
oil drain pan
oil filter wrench
ziplock bag (for used filter)
disposable gloves
rag or towel
-------------------
it's super easy to change your oil. if i can do it, anyone can. be sure to buy some replacement oil and filter and new crush washer, BEFORE you change your oil. Stupidly I almost forgot to do this one time.
I always use Mobile 1 for SUV 5w-30 and genuine Toyota Filters, which I get from the parts department at the local dealer. I also went to local medical supply store and bought some latex gloves. They are cheap to buy in bulk and I go through about 2 or 3 pairs per oil change. Helps keep the oil off my hands. you might also need to buy an oil filter wrench. helps you grip and rotate the oil filter off the threads.
1a. make sure truck is on flat pavement.
1b. place an oil pan under the truck. (i use cheap plastic sealable oil pan from walmart)
2. ratchet off the drain plug and let the oil drain. throw away the crush washer. sometimes you have to pry the crush washer off the vehicle. just take a flat-head screwdriver, wrap the end of the screwdriver with a rag and wedge the crush washer off. let the oil drain.
3. open up hood, look in the engine compartment and locate your oil filter. carefully unscrew the oil filter. this will probably require a filter wrench, which you can buy at walmart too. some oil will drain out into the oil filter cup. there is a drain in the bottom of this cup to get the remaining oil out. use a small plastic bottle or cup and hold it under the drain plug below the oil filter cup. clean up any excess oil and/or dirt, being careful not to shove anything down to the oil pipe that the filter screws onto. also be careful with the oil filter as it will still have oil inside of it. place the filter into a plastic zip lock bag and set aside. will help keep things tidy.
4. once the oil has completely drained, place the drain plug back into the drain hole, being sure to use a new crush washer. do not cross-thread and do not over-tighten.
5. screw on a new oil filter in the engine compartment
6. fill up engine with your favorite motor oil and replace oil cap
7. recycle oil and oil filter. call around town to see who accepts. it seems lately hardly any places locally will accept filters anymore, but they do take the oil.
