Use Dextron II transmission fluid in it or Dextron IIE don't try to use anything else you will regret it if you do. Transmission fluids are manufacturer/transmission specific specific. If you use the wrong type or kind you could ruin the transmission permanently especially and older transmission like yours.
Look in your owners manual or on the dipstick, or call a local GM shop to know for sure.
Yes it is just fine to run that. BUT....Why? It will not make your car go faster, cleaner, or last longer than the Regular 87. It is way out of reason to buy the HIGHER 93 when there is Regular available.
Anyone would think that it is leaking...you must open the hood, follow the fuel lines all the way back to the tank..Remove the vac hose from the pressure reg see if fuel is coming from there. It is not suppose to. Remove your spark plug and look at them for any sign that fuel is pouring into the cylinder. That may mean that your FUEL INJECTOR is not working correctly. Another words fuel injector is staying open, when it should be closed. The raw fuel is getting pushed out the tail pipe on the exhaust stroke....That will RUIN a cat converter and your O2 sensors.. Nether are cheap....and there is a high probability of a huge fire.
The clutch release ("throw-out") bearing has gone bad...Use a new clutch disc when you replace the clutch release bearing...or it could be the clutch master cylinder. Check the master cylinder first...Look for any sign of leakage from either component .
