Oil change on my 83 SC 911

[myslateblue911]

I have always had my mechanic do the oil change on my 83 SC 911 over the years. It is a simple task that I am going to start doing myself. I have done many oil changes on other vehicles over the years, but of course the 911 is not like any other vehicle I’ve ever owned. Any tips and tricks for doing oil change and filter on my air cooled 911 would be appreciated. Oil brand as well as weight? Oil filter brand? Process for draining the oil. How much oil should I expect will drain out of the engine to make sure I have a large enough a container to catch it all. Anything else I’m not thinking of. Thank you

I eventually had to get a 5 gallon bucket under the oil tank when I pull the plug - the oil drops so fast that my standard oil container couldn't keep up and ended up with oil everywhere.. just need something with big open top, and deep enough to keep splashing down...

Otherwise, pretty straightforward

I think this is a standard right of passage. I did the same thing with my first oil change. I had one of those waste oil jugs that lay under the car and have a depression on the side with a drain hole for the oil. Oil comes out of the tank so fast that it overwhelmed the drain and overflowed.

I have a big pan with a spout now. Thinking about adding a Fumoto drain valve to the tank. Can't use it on the sump, it would hang too low. But the sump only drains 2-4 quarts, and slowly.

I usually have to add about 10 quarts of fresh oil.

I use a "Performance Tool W4071" 4.5 gallon Pan for the oil tank that I got specifically for the warnings noted above and an old ""Performance Tool W4076"" 10 quart jug style pan for case, which ive had for years.. not necessary to drain both at same exact time but I do.

don't forget new crush washers, and maybe consider adding magnetic plug for oil tank

Like others have said: lots of oil and real fast!

Otherwise a great car to change oil on as you don’t need to jack it up.

Get a bucket that is tall enough or cut a five gallon one down that is almost to the bottom of the tank that you can still get your wrench into the space.

Do the tank first and then a decent sized pan under the engine for the rest.

I buy the Porsche factory filter from our host and use new crush washers for the plugs- tip: buy a bunch of the crush washers as they are cheap and then you don’t have to remember to get them each time.

I use a drain container such as the one below mentioned previously. Sturdy walls and plenty of room for the 10qts or so that you should expect to drain from both the oil tank and the sump.

The Stahlbus valve works great on the oil tank and replaces the plug. The advantage is that you can direct the flow through the tube into your container giving you a needed element of control. If you should need to change containers, you can always stop the flow by using a hemostat to clamp the tube temporarily. The other user hint is that it's a good idea to zip tie the drain tube to the fitting so that it doesn't come off.

If you get a combination collection pan and jug, DO NOT get one with a small hole. You want one with a large screened hole like this one. You can find it on Amazon and elsewhere:



This is the one I got 20+ years ago.

Add me to the "oil gushing out faster than my drain pan could handle" club. Make sure you have some kitty litter handy.

Buy this oil pan, and it’ll last forever. I’ve had mine for about 40 years.

I drain my used oil into used 1 gallon containers

I usually drain it cold with two pans they fill about evenly and dont overflow. Use a Mann or Mahle filter
