• Old question. There is no advantage to buying any higher octane than the mfr recommends. If your engine pings/knocks with that octane, you have an engine problem.
  • I just buy regular. Gas prices here are not bad, but in other parts of the bay area, they suck. Just depends on the height of tourist season and of course holidays.
  • I buy Premium. It is a better fuel in terms of the power it provides in the right engine, having a 90 or higher octane rating. It’s an unleaded, crude oil by-product with detergent additives and less polluting characteristics.
  • I usually buy the middle grade. My vehicles seem to operate better with it. 11/26/23
