Gas mileage by brand

I've googled this up and down and can't seem to find any discussion.

Hypothesis: Some fuel gets you better mileage than others. Duh!

What is the best fuel to use assuming all prices equal? I'm asking because my wifes friend claims that she used Esso 87 forever (Esso points), and one day she used PetroCan 87 and got nearly 20% better mileage out of the tank.
First question: do you usually drive in the city and that day you were out on the highway? No, she just drives to/from work same route every day and groceries on weekend.
Second question: are you sure? Yes, same results on a second tank.

I find the 20% claim really tough to swallow.

Implication of PetroCan 87 getting 20% better mileage than Esso 87: Esso goes out of business while everyone lines up at PetroCan as long as the price of PetroCan 87 is less than 1.2x the price of Esso 87.

Anyone validated improved mileage across brand/premium?

I have a thing for Shell 91 in my motorcycle because the bike just works better without ethanol, and the cost differential per km is about 1c, and that's my only bias.

For 91 = shell or esso
For 87 = any name brand

I always avoid using "no name brands" with the exception of Costco.

Costco is actually Husky IIRC.

I run V-Power because my car is tuned for 91. I like the idea that there's no Ethanol, but not really sure if it's worthwhile. I do get AM though.

Costco 91 and Shell 91 made no difference whatsoever to me, other than the price.

I use top tier gas, Shell, Petro, Esso
I noticed a slight mileage increase (0.2L/100km) with Shell, but that is not significant and could be within the margin of error, but since i get an extra 1% cashback on my credit card from Shell i have continued using it.

I use Costco 91 and v power if I'm not close to a Costco. There's no noticeable difference in l/100 between the 2 for me

It depends on the car.

If your car requires premium fuel (91 octane) Then shell should give you more kms per tank. However if your car takes regular or mid grade then generally there should not be much difference between brands. Its possible that the detergents that Esso uses are different then petro canada and her car just works better with petro canada.

Personally I saw about a 10% difference when I use Shell 0% Ethanol but my car is tuned for 91 octane compared to using petrocanada

Noticed with gas from RCSS/Loblaws, gets no where the mileage I would with Esso/PetroCanada.

However, the advantage between Esso vs PCan should be minimal, the claim may not have factored in weather / temperature which makes a huge difference too.

Well, if you're genuinely curious, why ask us - check it out for yourself...first.

Run a tank of Petro 87. Then, run a tank of Esso 87.

See if there is any difference and then get back to us.
