Most of the Premium fuel here on the West Coast is 92. Only certain Chevron and select “Petro-Canada” stations carry 94.
My LSC likes the 94. A LOT. It gets the 92 most of the time, because I cannot justify the extra 20 cents/gallon for commuting. When I go on a road trip however, YIPPEE!
Sunoco used to have 94 here in MA but no longer. The car only see 4-5k miles a year so I can afford to spoil it. The thing is these new engines are totally different. Computer adjusts for everything, the result is less rate of acceleration compared to the old engines.
