MT-90 is a 75W90 gear oil (viscosity about the same as a 15W40 motor
oil). Redline MTL is thinner, a 75W80W. Are you sure you weren't using
the MTL?

You don't say which Swepco product you used. I think the Porsche folks
mostly use their 201, which is available in multiple grades, up to a
250! Their 210 is an 80W-140, which sounds closer to what you describe.
