What kind of oil should I put in my 85 Porsche 944...

Great question but this is the wrong category, go to car audio category.

Probably Nox too high. Can also be engine too hot. Last time cooling system serviced? Also can be carbon in the combustion chamber ignites fuel too soon. Fuel delivery system and all sensors may be a problem. Bad or corroded connections can contribute to bad behavior of the ECU.

i have a 1983 porsch 944 .the brake and oil light comes on and the oil pressure guage drops when the clutch is depressed.any ideas?

It's kind of crazy to think of it now, but back in the 80's, Porsche thought this was the most stylish practical place to put the switch for the alarm system. Some of them have it, some don't, as it was an option.

Valvoline Racing 30 wt. no it should not burn oil ; do a compression test

Sounds like a warped head.
