RexyLexy415 Posted August 3, 2006 Share Posted August 3, 2006 Would it hurt the engine if I use plus gasoline (89)? Or do you recommend using premium gas at all times. Any ideas or how you use your gas choices. Although the 1993 SC 400’s do require Premium gas only? What is the were scenario that can occur if we do you plus 89 gas rather than the premium gas. The reason why I ask is because the gas prices in California are so expensive these days! Thanks.. Link to comment Share on other sites More sharing options...
