Straight 40 weight in the summer and straight 30 weight in the winter is what I remember being used in them.
27 years ago, when I was working understudy for the guys in Scientific Services, we were doing performance tests on the GT25 gas turbines.
"Starter motor" was a 12V71...the air starter would go, then the 12V71 would give two big revs, then run to full throttle while the fluid coupling between the V12 and the gas turbine was filled up, transferring the torque to the GT.
That was the bestest part.
