My first DIY oil change

Recommended Posts

After learning the shop recently used Castrol 5W-30, I'm going to try to swap it out on my own. I saw the write up (thanks Loren!) in the DIY section, and had a couple questions:

First off, since the filter is brand new (and this is my first time ever getting under the car), I'd like to keep things simple and leave the existing filter. All I want to do is drain whatever will drain and add the proper stuff.

How much oil will remain in the filter? I assume I won't need to add a full 9 quarts.

Also, where can I get the Aluminum sealing ring? Do I need to order, or does the average Pep Boys sell that?

Usually the sealing ring is sold with the oil filter (at least good dealers do).

I would remove the filter oil, let it drain for a few minutes then put it back on.

I would put 8 quarts in run it for a few minutes then shut it off. Wait 5 minutes and then measure the oil. One or two bars from the top is okay. More damage can be done if you overfill.

The sealing ring can be re-used if you feel comfortable doing so. By this I mean if you have an idea if it was not damaged by being over torqued or is not distorted and it still has some crush left as to conform to different sealing surfaces. If your are uncertain it's better to replace it.
