Isn't the advertised octane rating a minimum though?
No not really, they even have a small print stating that 98 is average on pamphlets that BP used to give out when they introduced 98.
Mobil states on the pump that synergy 8000 has a minimum rating of 97.5...
Yeah that'll be it. I was sure I have seen something about being a minimum.
