91 or 93. 93 is best but 91 is ok. Anything below is bad or may lead to future issues. I put in 89 once (3/4 tank of it) because nothing over that was around for 40miles and car ran sluggish. Seemed like it really needed to try in order to maintain hwy speed. I quickly burnt that off and once I got to Chevron, put in 91. It ran sluggish(ly) up until the second time I pumped in 91.
Manual states premium only as so does the sticker on the cap or near it. Will help prevent knocking (and
sometimes crickets).
