I know here we just had a scandal that for a whole year the oil company the owns the province was not putting supreme in the supreme tanks... "By mistake"I have sent mails to the big Fuel companies and received confirmation of what is in each grade of gas. I have never in my life (touch wood) had a bad gas situation. Not in any of my sleds, not in any of my summer power equipment or my mercury 300xs. Jus sayin
This refinery also supplies most stations no matter what the brand.
Ive never had bad gas per-se because they dont advertise octane at a lot of places here and they put stickers on the pumps that say "May contain up to 10% ethanol".
Then you go ask the attendant and they say " I don't think supreme has ethanol in it"
The individual stations here can choose what fuel spec. so it can change from location to location. ( i think that is just to insulate the big bad company from screw ups)
I've gotten bad diesel twice now tho.
OH BTW, 80% of the 300 000+ barrels per day of this refinery go to the US, hope none of that was put in the wrong tank also lol They probably only screw the locals anyway lol
