[QUOTE=teejay;797227]"hi, I have no proof or idea, but my car kinda felt slower with a full tank of fuel, give me money"[/QUOTE]

LOL

I learned from the best in the game...

If what u suspect is true then the operator would be in some hot water. But u have no way to prove it. If its keeping u up at night get in contact with the head office and let them know your suspicions saying u will get the fuel tested if it happens again or not get fuel from them again. I can tell - like u - the difference in the way my Caldina feels when on 95 or 98 fuel (Jap import designed for 100 tho)so don't let others make u think ur nuts.

Solid digs guys. Thanks for the advice ALLPAWS and howlfactor, I'll start off by talking to the servo staff first and go from there.

You realise janawani shindu the operator hasn't got a clue?

The truck drivers fill the tanks at the servo, for them to get it that wrong would of been noticed given they carry 10 times more regular unleaded than premium.

Well aware the counter staff probably do not know, but they will hopefully have the number for the manager who might.

janawani shindu will convert the sale by offering you 8 packs of gum for 30 cents

Fuel consuption will vary with traffic conditions, the way you drive, type of driving, ambient temps etc...
Butt dynos are like opinions. Useless.

Given you have no facts for your claim, It should make for an interesting conversation at the counter.

If there was any real proof, or engine damage then it would be worth pursuing.

Put it in the "But did you die?" catagory, fill up elsewhere and move on.

and the dumb keep getting dumber!
