Default Changing Oil?

I did a search, and I couldn't find anything; so here goes.

How does one change the oil in an MY02 RS?

Sorry if it seems like a dumb question

Thanks.

Buy oil.

Buy filter and little metal crush washer.

Stop engine.

Cover garage floor with old newspapers or rags and put on some rubber gloves so you don't burn yourself.

Unscrew cap from oil fill point in engine bay.

Place 5qt catch pan under oil pan.

Unscrew oil pan nut using a wrench or socket, being careful not to strip it.

Oil will pour out very strongly and may splash some.

Let oil drain, near the end you will need to move the pan back over some more as the flow decreases in strength.

After the pan is reduced to dripping slightly, move the catch pan under the oil filter.

Remove oil filter using oil filter wrench ($3-$5 at auto parts store). More oil will drip out.

Clean the area where the filter goes. Use a rag and get rid of any gunk that has built up there - You want a nice clean seal with the new filter.

Fill new filter up most of the way with new oil, and smear some of the new oil around the rubber gasket at the top of the filter.

Screw filter on using your hands. Tighten until it is tight, then give it another 3/4 turn. Don't use the filter wrench to put it back on.

Now put the oil pan nut back on with a crush washer on it, but make sure to clean the bottom of it off first. It has a magnet there to catch any metal particles. If it is dirty then your new oil will be contaminated immediatly. Make sure you don't cross thread it either, that is bad news and requires replacing the oil pan. It should screw back in pretty easily. After you have hand-tightened it give it a few more turns with a wrench. No need to be superman here, just make sure it is good and tight and the crush washer is crushed slightly. Now take a rag and clean up any spilled out from the underside of the car. If you have oil on the headers or other parts of the engine it will smoke and smell bad for a week or so.

Now put in 3 quarts of oil and whatever is left of the quart bottle that you used to fill the filter. So you should have 4 quarts total in the system now. Run the engine for a minute and check for any leaks with the engine running. If there are no leaks, then turn the engine off and wait a few minutes for the oil to drain out of the engine and back down into the pan. You should now check the oil level with the dipstick and add/remove oil as needed. Overfilling is bad and can cause leaks so double check your owner's manual to get the exact amount of oil that should be in there.

After a week of driving, check the oil level again and look for leaks.

I check the oil level and tire pressure every friday that it is not raining or nasty outside.

In addition to the great instructions by remarcable:

One trick that I picked up from another thread and that worked well for me is to punch a hole into the bottom of the oil filter (e. g. with a screwdriver) before removing it. This way you can drain the oil that sits in there, and there's no mess when you remove it.

Also, even though it's (hopefully) obvious: Check your manual to find out how much oil your car needs. It's 4.8 quarts for a WRX.

Do crush washers come in all different sizes?

Why fill the filter with oil before screwing it on? Doesn't that make it harder to put on and risk dropping and spilling oil all over the place if you don't get the filter on correctly?

Arrow FYI...

To All:

I highly recommend adding slightly less than is stated in the manual because all the oil does not drain out. My 02 OBS calls for 4.2 Quarts but I always add only 4. Also be leery of the dipstick because in my opinion I have encountered irregular readings!!! Sometimes the level is below the full & @ other times it registers on F.

Default Can't Get Oil Pan Nut Off!

Right now my car is sitting on jack stands, but I can't get the oil pan nut off! They must have used an impact wrench! What do I do? Buy an impact wrench to remove it?

NO!!! Dont use an impact
It comes tight from the factory.
get a 17mm wrench use the closed side and use a hammer and start whacking the wrench.

How is whacking on a wrech any different than using an impact wrech?

I, too would not recommend impact, but rather a steady application of torque. In order to do that, you'd have to lay under the car and push it with your feet. That may work, but I would recommend the "soft impact" method.

Get a LOOONG wrench and tug on it REAL fast, real hard. It is a form of impact driving, but it's a bit softer than a hammer or imact wrench.

If all else fails, whip out the hammer. If that fails. Take it to the dealer for this ONE oil change and tell them to not let the gorilla near the drain plug (except to remove it).

I tried again and pushed really hard - got some leverage by holding on to the underbody with my other hand - may have pushed against the tire with a foot for leverage also. I was kind of worried about using too much leverage and somehow knocking the car off the stands and crushing myself, but it didn't take that much force. However, I rolled up my windows and locked the car (which activates the alarm) while it was sitting partially outside the garage door so I could come up here and type in the last message. Doh! I forgot to deactivate the alarm, and the loosening tug set the alarm off. Luckily my remote wasn't too far away and I turned it off. Better than last time when I activated the alarm with the hood up to cool off - when I closed my garage door after mowing the lawn and shut the hood, the alarm practically made me deaf with the garage door shut and me struggling to get my dirty shoes off before running inside the house to get my keys!

Anyway, the oil change was successful, but I have a small oil leak either at the drain plug or filter. When the drain plug fell on the oil pan with the screen, I couldn't find the old washer. I assumed they didn't use a washer the first time and just put the new one on. Maybe it's possible the old washer was stuck to the oil pan, and I now have 2 washers on? Would this cause a leak? I saw some oil on the plug Sunday and tightened the plug more to gorilla specs, but it is still leaking in that area. Have to wait until Saturday to have time to jack it up and look under it again in the daytime.

The previous crush washer may have still been on the pan. The wide flat side faces the drain plug head. Subaru specifies 44 Newton-meters or 33 foot-pounds torque to tighten.

I had the same friggen problem! Except every place I went to for the crush washers didn't have any. I had to use the old one or none at all, so I used the old one. It was leaking for about a weak, and I *think* it has stoped now. If it hasn't I'm going to have to order a new washer from a store since they are too incompetent to actually have them on hand, drain the oil again, and then syphon it all back in when I'm done putting on the new washer. BAH! I also had the same problem getting the plug out! Had to take it to the place that monkeyed it on in the first place and make them loosen it. They definitely aren't going near it again. And...they get a monkey :monkey: !

Welcome to the club! Some time ago I wanted to check the torque on my lugs before driving to an auto-x, and as soon as I got working on the first one, the alarm went off. At 7am on a Sunday morning! In a residential neighborhood! And I had the remote in the house!

I got crush washers when I bought my oil filters, I ordered a sixpack of each from subaruparts.com. I think the crush washers are like $0.50 each. I doubt that the old one was stuck to the oil pan, I could hardly get mine off the plug during the first oil change. If anything, you may have missed it on there, with the torque specs they use at the factory it's completely flat.
