Question about 1993 Subaru Loyale
There was no warning lights or no over heating, the car went from 60 mph to 30mph, when i got home i noticed smoke coming from the catalytic convertor i checked the oil it was low so i topped it up with oil and it started first go but i havent driven it again
Low oil could definitely cause this trouble. When a vehicle gets low on oil, the friction increases and that causes the pistons to move slower. Slower moving pistons means lower rpms which in turn slows the vehicle. If this condition remains, the parts will not only wear prematurely, they will actually begin to weld themselves together. I would suggest you go to a local mechanic and have a compression test done. I hope it all turns out well for you.

There are only a few things that cause oil in the intake, most common is a plugged PCV (Positive Crankcase ventilation Valve), this causes pressure to build from the combustion process and forces oil into the air cleaner/air intake system, and in some cases out the oil seals, another issue is excessive engine blow-by, this is when the piston rings don't seal anymore and the pressure once again builds and forces oil into the air intake, the last and easiest to fix is an overfilled crankcase. Excessive oil burning of any kind will destroy the catalytic converter in a short period of time. How many many miles on the car, does it have excessive blow-by?

I had the same problem, and the reason was the sensors, will need to change the catalytic sensors some vehicle have two, they called front and back, get under the car and locate them, they have a electrical plug and are easy to remove, is like removing a spark plug but some require a special socket I hope this help
