Can any Civic X RS/turbo owners please shed some light if normal fuel can be used in turbo engines or Hi-octane is the only way to go? If yes, is Hi-octane from Shell, PSO, Total all same or you guys have some preferences?
Also if anybody can please share some tips on maintaining a turbo engine. I've heard about not swtiching off the car immediately after long trips & allowing turbo to cool down first. Any similar tips please?
