is more supply/demand. people use more fuel over summer, so they jack the price up to keep you from buying gas, winter the price drops cause theres less demand.
driving a sc car for the last 9 years, i cant tell if theres a difference or not in the blends, ( i cant tell you all 93 is not equal) i buy from one place only unless im way out of town.
funny how the same tune but gas from a different place can cause new found kr, go back to the good place and the kr goes away. things that make you say hhmmmm.
ive yet to try 87 in the regal. being i got meth injection now, im my mind im thinking the meth will make up for the 6 points lower octane. im just chicken still. ive chipped up one piston already, dont want another engine swap.
this will ruin your week.

for those who never chipped a piston before, this was wot top of second into third in the shift it started to make this pinging / crunching sounds for about 15 seconds, even after i let off cause im like thats not sounding good.
1/2 mile later the cel went off for a misfire but i already knew i smashed the spark plug.
