For an Infiniti I30, it is recommended to use premium unleaded gasoline with an octane rating of 91 or higher to ensure optimal engine performance. While regular unleaded (87 octane) may be used in a pinch, it’s best to stick with premium to maintain fuel efficiency and engine longevity. Always consult the owner's manual for specific fuel recommendations.

I have a 1999 I30 Limited and when the gas light comes on, I fill-up 17 gallons. Tank capacity might be 1 or 2 more gallons above that.
