Flipped Porsche G96 fluid capacity and recommended fluid

[Rich Kruger]

I've tried searching the web and GT40's but cannot find this info. Anyone know whats recommended. I did find the OEM capacity is 2.85 quarts but wasn't sure when the transaxle is reoriented. Also would Shell Spirax 75-90 but the best fluid?

Presuming its the G96/50 or turbo then 4litres of GL5 75/90 (synthetic)--maybe add an oil stabiliser if you're going to be fangin' it

Agreed with Chris....we normally use one gallon....which is close enough to 4 liters to be relatively insignificant.

Here's a technical thread on determining proper oil level for the porsche boxes: Oil level

1 Gallon for the G96-50 seems to be the consensus shared by Gbox guys as well. I went with Mobil Delvac gear oil, Swepco seems to be popular as well

Ok Thanks!

Just shy of a Gallon. Mobil Delvac. We ran this for all the 25 hr races. When we would use 1 gallon it would always puke a little into the catch can. If I remember correctly. use a tie wrap and stick down side fill hole on drivers side. 65mm from bottom seems to be the magic volume.
