tip fluid level
Thinking what I wrote earlier and then looking at my gauge at 65 C I made an error in my graphing.
So I was figuring where the fluid level should be because of the added .5 liter. Since I could not get the temp up to 80, barely got it to 70 once, usually only get it to 60, I needed to know where the fluid should be at 60.
Turns out the fluid for the nominal (mid-position) fill at 60 C should be ~ 2mm below the 80 numeral mark on the tube. That will equate to new nominal (mid-position) fill at 80.
If you can get it to 70 C, the level should be ~2 mm below the max 80 C on the tube.
50 C comes in at the 80 min mark on the tube
I was reading the temp from the PDT999 I borrowed from Ricardo.

How did you figure out the 60C fluid level? Is this just a linear extrapolation between the 30 and 80C marks denoted by Porsche?

Yes, I just did a linear interpolation on the mid points shown on the tube and then applied that to the new 80 C mid point.
oil coef of thermal expansion is linear and I just have to assume the cross sectional surface area is not changing much in the pan, so the level in the tube is linear with temp.
