Salutations: Unless you have gone for higher compression or your sensors are dead - you should be fine on 89 octane (midgrade here in Canada) fuel.. The knock sensors kick in and flatten the ignition if it thinks you are using too low an octane - but midgrade seems to work great for me on a 2.0 1989T.. -- J Dexter - webmaster - http://www.dexterdyne.org/ all tunes - no cookies no subscription no weather no ads no news no phone in - all the time Radio Free Dexterdyne Top Tune o'be-do-da-day Brian Setzer Orchestra - Jump Jive Wail http://www.dexterdyne.org/888/019.RAM pablo wrote: > > Could anyone tell me where to find information about the "AON" method Saab > seems to use when talking about fuel grade requirements?
