I bought my 1988 944 Turbo and it was using a lot of oil--about 1 liter per 500 miles. I changed the oil and put in a recommended Valvoline race oil (VR1) 20w50. It almost completely stopped using excessive oil--only about 1 liter every 1000 miles or more. This is factory spec (1-1.5 liters every 1000 miles is normal usage).
Apparently, these older motors love the heavier stuff. And the race oil has this chemical that's good for the seals (not sold in "off-the-shelf" reg oil).
I'm guessing the previous owner was running some modern, light oil like 5w30 synthetic.
Good luck, Dan
6.3 quarts, but don't stress over the .3 - call it six quarts even.
5 quarts without a filter, 5 1/2 with.
The oil pressure sensor on a Porsche 944 is typically located on the engine block, near the oil filter. It is mounted on the lower part of the engine, often on the driver's side, and can be accessed from underneath the vehicle. To identify it, look for a small cylindrical component with an electrical connector attached.
I use Mobil 1 10w30 works well with good quality filter.
the oil drain plug is located at the bottom of the sump under the engine. If memory serves you will need a hex bit to remove it.
6 quarts U.S. Dash warning indicator will light up with 5 quarts.
It is located just below where your oil filter and just above where you power steering pump are mounted in the engine compartment.
If the oil light stays on in a 1987 Porsche 944 despite the oil being full, it could indicate a problem with the oil pressure rather than just oil level. Possible issues include a faulty oil pressure sending unit, a clogged oil filter, or a malfunctioning oil pump. Additionally, there may be an electrical issue, such as a short circuit or a wiring problem affecting the oil pressure gauge. It's advisable to have the oil pressure tested to diagnose the issue accurately.

To check the transmission oil in a Porsche 944, first ensure the vehicle is on a level surface. Start the engine and let it warm up so the oil reaches optimal operating temperature. Locate the transmission dipstick (if equipped) or check the fill plug on the side of the transmission; remove it carefully and use your finger or a dipstick to check the oil level. If needed, add the appropriate type of transmission fluid until it reaches the correct level.
spark plugs and wires, oil and oil filter, air filter, check rotor and points in distributor, check belts, just basic maintenance.
For a 1983 Porsche 944, it's generally recommended to use a high-quality synthetic oil with a viscosity of 10W-40 or 20W-50, depending on the climate and driving conditions. Many enthusiasts prefer synthetic oils due to their better performance and protection at high temperatures. Always check the owner's manual for specific recommendations and ensure the oil meets the API (American Petroleum Institute) standards for that model.
