Yes. Your car has a larger block (2259 cc) versus the VTEC model (2157 cc), but your engine also uses a 9.8:1 compression ratio. That's close enough to 10:1 to recomend premium fuel. What kind of performance do you get with your engine? I've never driven one, but these numbers are nothing to sneeze at for an everyday 4 cylinder. Of course it's not VTEC territory, but I would assume it's not to shabby, either.
