oil extraction through dipstick
Has anyone have any feedback on using an oil extractor device on a 993. Apparently you insert a tube through the dipstick tube down to the bottom of the pan, you then pump a handle to create suction and the vacuum pressure created extracts all of the oil into its own canister (7 quarts so you would need to do it twice, automatic float shutoff when you reach almost 7 quarts).
They seem to cost in the range of sixty dollars and I was told that you are able to extract more oil using this method than just allowing the oil to drain via the drain plug.
Obvioulsy you still need to change the oil filters, but it would apper to me that to remove the oil, this is an easier, cleaner and maybe better way to go about it.
Appreciate to hear some feedback.
Thanks

The hard part about 993 oil changes isn't the draining of the old oil, it's changing the @%@!! filters. So you'd be spending $ on a part which really doesn't save you from the heavy lifting.
You can get 10.5 quarts out using Robin's DIY instrutions at http://p-car.com/

see thats what i was told......u cannot get all te oil out by just removing the drain plug.......apparently with the extractor and the vacuum that is created provided that the tube is bottomed out you will get all the oil out.

The product you may be referring to is sold by Griot's Garage (and maybe others)as the Oil/Liquid Extractor. I have one and use it regularly, on the theory that my oil contaminates quickly with the repeated shorter trips I end up making. It's very easy to use, and when the oil is warm you can get out every bit that's not in the lines or the filters. I use it on other cars, too. No complaints. I should point out that this is not a substitute for regular oil change services by someone qualified (not me!) Just a precautionary measure.

I always drain the oil, I have older 911, but in principle, my opinion is, that using the extractor is not a good idea because when draining the oil, you get the small metal 'dusts' or any other small 'dirt' obkects out of the system, because they are usually at the bottom of the pan and when draining, they drain out with the oil.
Or am I wrong about this?

Thanks for the input...based on what Robin is saying (which I am sure is absolutly correct)there is probably no benifit to using such a device (that is if you are replacing the filters at the same time).

Many other countries use the vacuum method too, I don't think there is anything wrong with that method, is just that it doesn't help much in making the job easier for the 993, because draining the oil out of a 993 is not the hard part.

Maybe in mainland europe, but not in the UK.
They still drain into special cans, which are normally emptied into barrels. The garages then have to pay some environmental tax to cover disposal costs.
Well actually the punter pays, but thats another story
I'm not quite sure how you would vacuum out the oil from anything but a dry-sumped angine anyway. Where would you place the pipe on an overhead cam engine with only a dipstick going anywhere near the sump ?
I'd never heard of these things until it was mentioned here.
