Re: [Tech] Which grade of fuel should I use
As MooJon stated, running lower-grade gas in a turbo (or supercharged) vehicle is NOT a good idea. The boost creates cylinder pressures FAR above those found in a normally aspirated engine. The high pressure causes lower octane fuels to spontaneously combust before the plug fires. It pounds the crap out of pistons.
