Cars That Use Premium Gas
Typically, three levels of gasoline are available: Regular, plus or premium. Gasoline fuels are rated depending on their octane level. Regular gasoline has an octane of 87, plus has an 89 octane rating and premium gasoline has a 91 octane rating. Before the early 1990s, engine knocking and other conditions could occur if the correct fuel was not used. However, today's engines use computers to regulate performance based on what octane is used.
