    I know on the 1.9L in the wiring schematics there is an octane adjust plug connected to the ECU. Don't ask me how it works, but this may be it.

    Here in eastern Pa., Sun Oil Company "sunoco" has their own terminals and only Sunoco labeled tankers deliver product to their retailers. Still, these terminals are open to other retailers who wish to buy pipline gas for their stations. There just buying pipeline gas with "govt. spec" additives for the higher octanes, not Sunoco Ultra which is higher than spec Hi-Test. I trust Sunoco and the other major brands with their "additive packages". Around here we have Sheetz gas stations and twice a couple miles after filling up my escort it lost power dramaticly [45mph top speed] on the pa.turnpike, and my Mercedes started pinging bad after a fill up. On my 93 Mercedes theres a Resister that adjusts the timing for the octane requirments of the country the car is destined to. If I cut this resister, I now have a EuroSpec Benz and can only run the highest octane gas available. I don't want to do this becauce of traveling and not being able to get decent gas. Maybe it's changed since I've been out west but I can remember gas stations with 89 as their highest octane. Once that resister is cut thats it, The engine dos'nt have a knock sensor like my old 91 turbo Saab to adjust for crap gas.
