I highly recommend using premium ALL the time. The cost of premium is rarely $0.30/gallon more than regular 85 octane. For our NSX's 14ish gallon tank, that's only a $4.20 difference. Heck, its only a $6.00 difference for the entire tank of my 20 gallon Expedition. I usually see a $0.20 difference which puts the cost at $2.80 and $4.00 respectively.
Is $2.80-$4.20 worth it? A $6 difference is worth it to me.
