Bobbeh Posted December 25, 2002 Share Posted December 25, 2002 You want to put the highest octane fuel in you can for best performance. Anything Super unleaded is best, Optimax is my fave but it costs. Example of BHP loss on a new Subaru Sti I read/heard about (think it was on Top Gear or 5th Gear).. normal unleaded fuel 225 BHP, with Optimax it was 261 BHP.

michel lane Posted December 25, 2002 Share Posted December 25, 2002 I Think i heard from somewhere that on most jap imports they have been tuned to run on oct 100 ? so they recommend you run on super as an eqivalent. The U.K spec ecu are design to run on standard 95 octane.. i could be wrong??? Quote Link to comment Share on other sites More sharing options...

Terminator Posted December 26, 2002 Share Posted December 26, 2002 Your car will run on 95 fuel, just remove the efi fuses for five minutes and the ECU will learn the new fuel charateristics in a short while. Jap specs where designed for 101 ron, and that is what many of us aim for, Optimax and booster is as close as you can get to 101 without race fuel or adding some nasty stuff to the fuel. If you have cats on bottle of millers to 50L of fuel is OK with no cats you can go to a higher level of booster. Quote Link to comment Share on other sites More sharing options...
peter richards Posted December 27, 2002 Author Share Posted December 27, 2002 hi terminator , i think thats what the service manager was talking about .they seem to be quite interested in the car . customer service is good .one small touch , one of the wheel covers had come off , when i picked the car up after the service they had fitted one free of charge . by the way phil ,just come off the phone to james , he has given me some very good prices on the wheels . once again thanks .
