Yup can't beat 11.5 cents per litre... BUT.. as with anything.. things aren't always as they appear..
I can't prove without reasonable doubt, but I believe I get waay less mileage with Superstore Gas compared to Petro Canada.
I've been trying to compare the two equally, but I keep ending up going on road trips, and its hard to compare highway driving vs city driving. But so far, it seems I've been getting about 50-60 kms less on a full tank with Superstore compared to petro.
I drive a 99 civic, 41 L tank I believe, and with Petro gas i seem to get about 550 kms before my gas light turns on, whereas with superstore gas the light goes on at around the 500 mark.
Regardless, I mostly fill up at SS, but sometimes goes to PEtro as its 7 cents off/L on wknds only.
If someone knows a bit more on where SS gets there gas or if there is actually differences in gas, that would be great
