- I just bought my 1988 supercharged mk1. There is a switch that lets me designate between regular and premium gas. Since it is forced injection, I want to use the premium gas. What does toyota consider premium? 92? 93? 94? I am looking for two things. What toyota recommends, and what people have found works themselves best.
