95 Octane Fuel For Mitsubishi Gdi Engines?

[lilzackie]

Do we have to put only 95 octane fuel for mitsubishi GDI engines??If not what happens??

[fuzzo]

yes you should... i pumped 90 by mistake once and i didn't get to travel 1KM before i got check engine light

Using 90 Octane is not good for the engine..The GDI has a very small nozzle that sprays fuel into the engine combustion chamber, Using lower graded fuel than the recommended would result in the nozzles getting blocked and would reduce overall efficiency.

If you have used 90 Octane in a GDI Engine, Suggest you run the tank almost till empty, and then refill with 95 octane + Fuel System Injector cleaner - BG44k or Valvoline .

90 octane has a reputation for being dirtier (more "rodu" etc) than the 95 octane and that's probably why it mucks up the injectors.

(using lower octane than recommended does result in poorer performance and enging knocking, but than in itself wouldn't block injectors)

Guys, any idea what the fuel consumption on GDI montero's are in city running?

I've seen the trip computer on a 3.5L V6 GDI indicate 3 Km/L, mind you it was a SWB one too
