I do the oil changes on my 997 regularly (to speak with JFK: because it's easy. not because it's hard) but I will now finally tackle changing the oil on my aircooled 964 and no longer pay my mechanic a fortune to do it ;-)
Changing the oil filter looks like it's going to be a mess

• Is there a recommended wrench to get it off?
• Is there any genius tool that I can put below the oil filter housing to catch the oil that undisputedly will come gushing out?

I use a screwdriver and poke some holes in the oil filter prior to opening up oil resevoir plug. This will also let the filter be drained (but not fully). After draining both plugs underneath the car I use the screwdriver inside the filter as a lever to loosen it. When loosened I tape shut the holes and put some paper towels underneath the filter and remove the filter by hand. Very little mess.

I do a similar routine as previous post. probably only differ in the order drain tank reinstall its drain plug
then pop a hole in filter. drain case put plug back in. pull tanks plug again let drain over night. In am new crush washer on tank plug pull case plug for last drain and new crush washer. like above shove screw driver thru filter then wipe what little oil that will come from filter new filter 8 quarts or liters start car then add 2 more quarts or liters till dip stick say full

There is a seperate drain plug on the filter housing (inner wing) if you need. Not everyone uses this, as given some time the oil will eventually drain down from the filter with the crankcase plug out and the filler cap off.

I've had very good luck with this style of filter wrench.

Any old adjustable oil filter wrench either the metal or rubber band style will do what you need it to.

Thanks Y'all
i got one of those off amazon.Seems to be a good fit
I'll know for sure this weekend when I'll do the actual oil change

Have these as well. Have come in really handy for any oil filter. The only grips that would also fit the 968 fuel tank level float and sender cap.

My last oil change went smoothly. The jackstand was in the way of the oil pan. I had a flash of brilliance, and used an offset funnel. The funnel was too narrow…

The best advice on an oil filter wrench, don’t use one. When the filter makes contact just turn it 3/4’s more, and you’re done. You should be able to remove by hand. The screwdriver is good advice for leverage if you need it. And remember to tape the hole, ask me how I know.

And good advice on taking the right rear wheel off to vent the oil filter. Unfortunately my MY 1990 doesn’t have the vent… Letting the filter drain overnight may be the way to go.

I just did this today for the first time. I can not get a drain pan under the thermostat drain when the car is on the lift so I cut off the top of a rectangular plastic coolant bottle and used that as a funnel. I could hold the handle without my hand getting hot. A couple of paper towels under the filter helped but still a little spillage- not much though. Suer would be nice if there was a way to get all the oil out of the cooler and lines.

If you warm up the engine until the oil thermostat opened, you get about 85% of the oil out. The system holds about 12 quarts of oil and I usually get 10 to 10.5 quarts out with the thermostat open.

summary: the oil wrench worked great and thank you guys for the warning about the potential mess when draining the oil reservoir.
I MacGyvered myself a little chute - or you may say 1/2 funnel out of an aluminum turkey oven tray.
Worked like a charm
