CAUTION
Use of a fuel which is low in quality or use of an inappropriate
fuel additive may cause engine damage.
J Fuel requirements
B Fuel Octane Rating
Your engine is designed to use only unleaded gasoline with an octane
rating of 87 AKI or higher. This octane rating is the average of the Re-

gasoline filler nozzle. Under no circumstances should leaded gaso-

standards as indicated on the underhood tune-up label. It is designed
to optimize engine and emission performance with gasoline that
meets the clean burning low-sulfur California gasoline specifications.
