1986F150Six Posted December 7, 2017 Share Posted December 7, 2017 Not too very long ago [10 years?], gasoline sold by the name brand stations here in the Southeast, had a $0.10 per gallon cost increase for each higher grade of gasoline. This had been the practice for years. Keep in mind that the different octane gasoline sold at the pump is accomplished by blending, either at the refinery, the distribution point or at the station. For example, 87 octane was $2.50, 89 octane was $2.60 [+4%] and premium was $2.70 [+3.8%]per gallon. I will highlight in bold the approximate percentage increase. When gasoline prices neared the $4 mark, the difference between each grade increased to $0.25. The blending was still the same. When prices peaked, 87 octane was @ $4.25, 89 octane was $4.50 [+5.9%] and premium was $4.75 [+5.6%]. When the gasoline prices fell back to the currently lower prices, the grade level increases remained at +$0.25. Keep in mind, the blending practices are still the same. Currently, 87 octane is $2.12, 89 octane is $2.37 [+11.8%] and premium is $2.62 [+10.5%] per gallon. Just thinking. Link to comment Share on other sites More sharing options...
Gary Lewis Posted December 7, 2017 Share Posted December 7, 2017 I think you've just figured out their cunning plan to get more money w/o making it intuitively obvious to the casual observer. Link to comment Share on other sites More sharing options...
ArdWrknTrk Posted December 8, 2017 Share Posted December 8, 2017 Tell me how they blend it down to 87 octane while adding 10% or so ethanol at 113 Ron? E85 is somewhere between 100-105 octane and if you can take the hit on mileage will really make a lot of power in a properly set up flexfuel vehicle. Premium is hovering just below $3 a gallon here in the NYC metropolitan area. So i would say your $.25 price difference is probably spot on.

I also, have always blended my own. Link to comment Share on other sites More sharing options...
