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.

There are several different methods used in the world for octane ratings. In the USA and Canada a different scale is used than most of the world. This is 4 to 5 points lower than the scale used in the Philippines. Hence USA and Canada octane ratings are 4-5 points lower than the scale used in the Philippines. So 87 octane in the USA would be called 93-94 octane in the Philippines for the same gasoline.
