Hi, unleaded over 92 octane is good but you can run 89. Change oil very often if you have supercharger SSEI
a supercharged muscle car engine
R134
all newer vehicles take r134a refrigerant.
It came from the factory with R12 Freon. It may have been converted to R134a. If so there should be a sticker near the compressor. If it has not been converted, I suggest you do so, as the price of Freon is prohibitive.
