I have a 1997 Limited with the OHV V6 here in Manila, Philippines. The local Ford dealer advised me to just ran the thing on ordinary unleaded which is 93 RON. I sometimes fill up with 95 RON or even the pricier 97 RON and do notice that it does provide a significantly stronger 'kick'.
Then I read here that you guys across the Pacific are using 87 octane fuel as the recommended grade. Am I missing something here? I can't buy anything lower than 93 octane. Even the local E10 is at 95.
I guess its a bit pointless to ask after running thing for 10 years but I do want to avoid that inevitable overhaul for as long as possible.
