1990 Firebird Formula- Vin F TPI Fuel Type
Hello,
I was just reading my owners manual today for my 90 Firebird 305 TPI(VIN F). The manual states to use premium 91, and I was not aware of this until now. I just want to make sure I am interpreting this right so I start to use the right fuel. I have been using 87.
