Oil extractor question

[freesaints]

Has anyone ever used an oil extractor when doing an oil change? I've used one on my NSX and it works great and was so much easier than the traditional method. The volume difference aside, not sure if there were other reasons why one wouldn't work. I'm curious to hear if anyone's successfully used one.

How would get out the used oil in a 911 crankcase using a suction method? For most engines, you have a direct route to suck the oil from the bottom of the engine out. Keep us posted.

How would you extract the oil in the engine?

Pushing a low profile open container/oil pan under the engine and open the plugs is so easy, at most backing up on a couple of boards to gain an extra inch is all that's needed.

Getting the oil out of these cars is super easy without the addition of special tools. One word of caution. About a year ago I overfilled my car. In an effort to remove some of the oil I used a large syringe type device. It had an extension on it which allowed me to reach in the full hole and remove oil. However, when I pulled it out the extension was left behind in the oil tank turning a seemingly simple exercise into a half day of fiddling to get that stupid tube out through the DRAIN hole. My 7 yr old was with me when it happened and learned a few new words. He tells EVERYONE. So I figured since the entire third grade knows, I’d share it here to help someone else avoid the pain.

The oil tank drain plug has a magnet in it. I like to examine it and clean it during an oil change. I might use an extractor or some modern car with a pain to get to drain plug cover by panels. The drain plugs on a 911 are pretty simple to get to. No way would I use anything more than gravity and the eays to get to drain plugs.

A manual or electric transfer pump will do it if draining isn't an option for some reason.

Thanks for the replies everyone, just thought I'd ask since nothing popped up on the forums and it made life very easy on my other cars. Not that it's difficult with our cars, but this satisfied my curiosity.

I'm a bit anal about oil in my engine, and don't love the idea of sticking something in there unless I'm 100% sure it's clean. I'd probably spend more time doing that than I spend draining my oil the old fashioned way.

Fumoto oil drain valve on the oil tank makes it
more manageable.
No way to get the crankcase oil out with it,
but that's easy enough.

@87maniac - the Fumoto oil drain valve looks interesting but I couldn't see that they supported Porsche on their site. Which one do you have?

[87maniac]

freesaints- It's been a couple of years,
so double check, but I believe this is what I used.
'87 911. There is Plenty of ground clearance.

[911pcars]

Don't use in place of the crankcase drain plug. Not enough ground clearance.

The 911 is not a car that benefits from sucking oil out the top, unlike other makes. I have had some cars that were a royal pita to drain because there are belly pans to remove and then the oil runs over some cross member or a suspension component making a big mess.

The 911 (pre-964) has two drain plugs that are right in your face once you jack up the car and drain straight down. The only challenge may be that you have a lot of oil in the tank, and some people have made a mess putting a 6 quart pan underneath it! As mentioned, there is significant volume in the engine case that can not be reached with a sucker and I would not want to stick a suction hose into the oil tank, as there is an oil tank level gauge you may damage in the process.

The later air cooled engines are more involved, with the tank drain plug hidden under the side skirt, but the large oil filter is in there too, so then you are not really saving any time either, sucking on the oil tank ...

I hate those oil drain valves with a passion. How hard is it to undo a drain plug and how much time do you save? The valves are pretty safe, but they do stick out and can get damaged - Murphy NEVER sleeps.

I like the the Stahlbus drain valve on the main oil tank, mostly to slow the drain of oil as it otherwise drains so fast that my container can't keep up. Unlike the Fumotos and similar, it can't be opened on its own, you have to use the accompanying attachment, which I just leave in the car's tool bag.
