steviej Posted August 13, 2004 Share Posted August 13, 2004 This is what is in the 2002 ES manual. Fuel selection: Select premium unleaded gasoline with an Octane Rating of 91 (Research Octane Number 96) or higher for optimum engine performance. However, if such premium type cannot be obtained, you may temporarily use unleaded gasoline with an Octane Rating as low as 87 (Research Octane Number 91) steviej Quote Link to comment Share on other sites More sharing options...
