What tools do you have? How are you going to lift the car? How are you planning to catch the used oil?

It's good to take it on yourself. If you follow the logical steps, it's very easy to do.

I've used Mobile 1 for quite some time, granted a local shop had Valvoline fully synthetic for an amazing deal so I used that last time, but Mobile 1 is where its at. Job should take you no more than 20-30 mins TOPS.

Its the gasket that gets replaced when you remove the drain plug.

I've never replaced the crush washer in any of 3 of the 2GS's ive owned and i put about 200k miles between the 3 of them. oh and i read somewhere that mobil 1 is not fully synthetic but they won a court case where they can display fully synthetic on the bottle because of the process of refining the oil or something along those lines. Personally i like pennzoil and castrol.

Maybe you can get away without replacing the drain plug crush washer but I got oil drip spots on the garage floor the time I didn't replace one on my first Lexus. The crush washer also helps prevent stripping the threads since it actually does "crush" as you tighten the drain bolt. Crush washers are cheaper in a 10-pack. Each of the last several 10-packs of OEM Toyota/Lexus oil filters has cost right at $40 including a 10-pack of crush washers.

I've never had to put a Toyota or Lexus car on jack stands to change the oil but I do sometimes raise the car on the front passenger side a few inches with a floor jack. (I reach under the car and never put my body under it.) I lower the car down while the oil is draining from the sump. I've got a separate catch pan for removing the oil filter.

You will need a 14 mm socket to remove/reinstall the drain plug and a 10 mm socket to remove the fasteners holding the engine undercover. A short 2"-3" socket extension might be helpful. You GS likely has plastic threaded inserts at the front of the undercover so gently tighten those when reinstalling the undercover so you don't strip the threads. If someone else has been changing your oil, you might find some of the inserts already stripped -- I keep a couple of replacements on hand because I occasionally strip one too.

Assuming you are going to take the oil to a recycler, you will probably need a a couple of plastic jugs and a funnel to get the oil into them.

And something to keep your garage floor clean -- a drop cloth of some kind ... a few layers of newspapers can work too. Have some rags or paper towels handy. I buy surgical gloves by the box to keep my hands clean while doing the dirty work on cars.

Wiggling around on a cold garage floor is not my idea of fun. I have a creeper with a padded headrest.

By now, I've got oil changes down to a science. I just calculated I've changed the oil on our Lexus and Toyota cars 88 times since I bought the first LS in 1990 and who knows how many times before that since I started changing oil on the family cars in the early 60's before I was old enough to drive.

I don't have a plastic cover under the oil pan. I am not sure if there is supposed to be one. So I can reach the drain plug without lifting the car and removing other things.
