[s-cars] Rear main seal leak - try dino oil again?

I didn't realize that the clutch would be shot. Someone mentioned that you can spray brake cleaner on the flywheel from the timing window and 'clean the oil off.'
Should I plan on a new clutch or have my mechanic evaluate it when he drops the transmission?
A closer look at the old case of oil and I discovered that it wasn't 20w-50 but just a mix of 10w30 and 40.
Probably not worth potential unknown risks of changing back to dino or using an additive. I did just sell the old mtm 1+ chip so I have some $$ to put towards the seal replacement. Not a job that I want to tackle myself.
My mechanic will just be getting back from a week vacation so I imagine that it may be a week or so before he can schedule me in. Clutch only slips in the higher gears at higher power application.

I would argue strongly against any attempt to use a seal sweller/restorer.
First, it swells all the seals, not just the leaky one. Sure it may stop
the leak, but it softens and weakens the seals which drastically shortens
their lives (again, all of them). Second, the damage is done. The clutch
is soaked in oil. How is stopping the leaking going to help that?

Last week I reported that my clutch was slipping. Upon further inspection
it appears to be the rear main seal that is leaking and causing clutch not
to hold new RS2 power.
Currently running winter 5-40 synthetic. Since its (supposed to be)
springtime now I was going to switch back to mobil 1 15-50 synthetic. But I
noticed a case of old Penzoil 20-50 race oil left over from my old LT1 vette
days (yes I should have kept that car).
Should I give the dino oil a go first in hopes of abateing the rear main
leak?
I figure that I might as well try it as the case of penzoil will probably
sit there another 10 yrs.
I noticed on 'two-guys garage' this morning (I have no life) that bars-leak
has a rear main seal 'restorer' product that they used on an old T-bird.
But who knows what it would do inside a turbo?
