What do you think the small Gas Station like Pioneer and XTR

There are a couple of these stations around my area, their price is always around 5 cents cheaper, what do you think their gas? Trust them? There is one called "Canadian Petro", I don't know and will not try it.

im sure they have teh same gas as other major brands but dont have all the additives such as engine detergents etc ...

personally my gf went to husky and used their stations and noticed a significant drop in mileage where usually $50 would last her 1.5 weeks ... it lasted her 3 days lolloloololl sooo could contain more then 10% ethanol and stuff like that

ed116 is pretty well on point. The independent stations buy gas from the same refineries and may or may not get the same gas as the regular stations. Depends on what is on the truck. Sometimes they have contracts with refineries. You can ask them who they get the gas from.

Those additives don't improve mileage, they just clean your engine. I don't understand how you could get different mileage, probably some other factor accounted for that.

higher ethanol content means gas burns quicker thus affecting mpg :)

usually gas stations have up to 10% ethanol but husky could have had more during that batch ...

XTR gets the gas from Sunoco, not sure about Pioneer. I do get gas from Costco when the tank is very low, not worth to top it up when wait in a long line.

No question ethanol makes a difference, but your original post said it qas a difference 3 days vs. 1.5 weeks(10 days), hardly believable to be due to gas alone.

Best to rotate different brands. Save bit of money.

I agree 100%, Costco, Pioneer and Petro Can. I did try XTR today with full service.

That's not what higher ethanol content does.
Ethanol contains less energy per volume than gasoline, but at a higher octane rating and burning cooler than gasoline, so it's a great way to raise the octane of what comes out of the pumps.

Yes it raises the octane but, that is so refiners can use a cheaper, lower grade cut to send to the customer....add ethanol and bump the octane. The mileages does suffer a as result.
This is why premium without ethanol gets such better mileage.

Yes, Ethanol contains less energy per volume (https://en.wikipedia.org/wiki/Gasoline_ ... equivalent) and it's stoichiometric is much richer than gasoline (http://www.ultra-gauge.com/customer_sup ... article=29), but the average E10 blend we see everywhere, except for Shell 91 octane which is usually ethanol free, contains about 2% less energy than 100% pure gasoline.
Even if the net fuel mileage difference ends up being around 5%, that's only 25km on 500km... barely noticeable.

I personally have never noticed a difference between Shell 91 ethanol free and any other E10 blend, even Esso's 93 and Petro 94 - my car REQUIRES 91 octane too.
