I know I don't get all of it out but I'm doing about 3 oil changes a year so I figure 90% of the bad oil is being replaced with each change.

I have set an empty 2 # coffee can under the drain when the flow was down to dripping, and left the car sit over night.

Now I use a hex socket and just pull it away with the plug attached.

Water and washing up liquid,that really keeps the engine clean and has the benefit of cleaning your garage floor when the RMS goes.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I am attempting to change my oil (first time) in my '99 996 C2. I have the filter and gaskets for the filter and drain plug. My problem is getting the car jacked up in the rear to perform the drain and change. I have a floor jack and two jack stands....and I feel like an idiot but I can't figure out how to get the car up on the jack stands in the appropriate jack points. Please help!! I would also love a complete oil change tutorial if one exists... Thanks in advance!
I don't jack my car up when I change my oil. I back partially out of my garage so that the rear of the car is hanging over the lip from my garage into my driveway. This gives me plenty of room to get under the car. The 996 is one of the easiest oil changes I've ever done.
Is something like this an option for you?
Just buy a couple of 2 x 12s, cut them maybe 18" and 24" and nail together. Make 2 of these and use to raise the rear up 3.5" by backing the rear tires up on to them.
You can buy a plastic filter wrench at Walmart for a couple of bucks that works fine. Warm the car up a bit and put a large enough pan under to collect 2 gal of oil minimum. 8mm allen wrench I believe will remove the plug. It's all intuitive from there. GL
Absolutely DO NOT lift the entire rear of the car from the engine case!!! The engine mounts were not designed to carry the weight of the entire rear of the car.
I use a low profile floor jack (Harbor Freight 2.5 Ton steel ~$70), and I drive my rear wheels onto 2x12s so that I am able to reach the rear cross member. That is the proper lifting point on the rear.
1. Drive rear wheels onto 2x12s (or similar, just get it high enough off the ground to achieve ample clearance for the floor jack to reach the rear crossmember).
2. On both sides, one at a time, lift the car from the rear jacking point high enough to get a jack stand under the front jacking point.
3. Once the front of the car is supported by the 2 jackstands, lift the rear from the rear crossmember, and place 2 jackstands under the rear jacking points. NEVER, under any circumstances, get under a car supported only by a floor jack.
4. Change oil and filter.
5. Lower car in reverse order of above.
With the car up on 4 jackstands, it ensures the car is stable and level.
The correct oil filter cap size is: 76mm; 14 flutes (B cap). This can be purchased from any auto store for about $6.
See picture below:
Oil drain plug - red circle
Rear jacking point - green circle
1 Make sure that your oil drain pan will slide under the car while it is on the ground.
2 Jack the car from your favorite rear jack point ( left or right) right gives more oil filter remove clearance
3 Place the pan
4 remove the plug
5 let the car down for 15 min
6 Jack the car replace the Plug and new crush washer
7 remove the oil filter
8 replace with new filter E/W new "O" rings
9 Clean engine as necessary
10 Refill with "best oil for your car" (see 10,000 posts on oil thread for defination of best oil)
+1 This is the easiest way to do it unless you have the option that Dennis mentioned. All this building blocks of wood and jack points talk is giving me a headache.
Super easy to do. I don't us a jack, I built a set of ramps with 10 bucks worth of wood and a saw. There is a lot of oil, so make sure your container can hold it all.
So, tell me....what is your choice of oil and why?
at least the 996 drain comes out horizontal, I did a change on my Range Rover Sport with the plug that comes out horizontal, suffice to say my location of the drain pan and the hot oil trajectory were not aligned and both I and the garrage floor got a good dousing of hot oil
I press the drain plug against the pan whilst unscrewing until all the threads have fully backed out, then quickly pull the plug away, ensuring a mess-free drain.
There is a good youtube video on the 996 oil change someone did... i recommend you watch that, and as they say it is a piece of cake.
I have been waiting for someone to counter what I see most other websites recommending to jack the rear from engine case to get on stands (quite a few reputable sites). I've never had a car that did not recommend a cross or sub-frame member as the preferred center lift point... why is this subframe not a recommended lift point in the manual? Porsche only lists the frame sides...
I'll go with the cross frame (if I can get my jack to it). Thx!
Been changing the oil in my Boxster, Cayman S (2 times), Turbo for a while and I just back the car up on some Rhino Ramps.
This gets the engine of the car high enough to get under the car and do an oil change.
The car on ramps doesn't effect the amount of oil that is drained.
Just be sure the engine is warm -- IIRC the coolant temp wants to be at least 70C (158F) -- and let the oil drain for around 20 minutes.
I would never left my cars by any other "lift points" other than the factory lift points.
If I were unable to use ramps for some reason, I'd invest in a nice lift that would be flat/low enough to driver over/on and then would raise the car high enough -- safely -- to get under the car.
The lift would use the factory lift points so I could use this to raise the car for oil/filter servicing, but also use it to remove the wheels for a brake job or other work.
Sincerely,
Macster.
The cross member is a safe point to lift the rear of the car from... The other day I went to a Local Club members home to teach him how to do his own Brake job. For the DIY guy, in his home garage who can not nor does not wish to purchase a scissors lift, that is where I recommend to place the jack. Then you can place both of your jack stand either at the chassis points or on a secure location of the Sub frame.
This may seem like a stupid tip but just remember after you've run the car to heat up the oil and then go under to remove the plug - remember that the oil is %&*# HOT! Even wearing thick rubber gloves the oil almost melted them to my hand... Now I use a hex socket and just pull it away with the plug attached.
I just back mine onto trailer ramps, easy and safe. Less than $50 bucks at most stores;

quicker and safer than floor jacks.
I really like this reply Nick, nice and simple.
Has anyone else done it with a plastic filter wrench and allen wrench?
I'd rather not buy a fitting just for the filter removal and mess with torque wrenches (I know, do it right or don't do it at all yea yea..)
this is such a silly thread... I back mine on to a set of ramps. But I have done it with out lifting at all.
That pix of the guy jacking his car with the engine case... OMG.....Put down the wrenches and slowly step away from the car.
Agreed. and with a low profile oil drain pan I then let the jack down gently so the oil can flow from the front of the car (oil cooler is there) and let drain for an hour or two.
Backing up on ramps should in my mind leave oil in the oil cooler and lines. I have set an empty 2 # coffee can under the drain when the flow was down to dripping, and left the car sit over night. In the morning the can was full to the point of overflowing.
Refill takes all of 10 quarts, doing it this way......
jacking a car up by its engine is pure heresy in my book. NO EXCUSES.
Wow I had no idea that much additional oil would come out during that period of time.
I know I don't get all of it out but I'm doing about 3 oil changes a year so I figure 90% of the bad oil is being replaced with each change. It helps to make the whole process of changing the oil into just a simple 10 minute procedure.
As for jacking the engine, the only time I've done it was when disconnecting the motor mounts. I was nervous the whole time!
