- I'm fully aware of the rule about the 5% average. Hence, I was surprised to see the statement on Husky's website about their 87 in Calgary not having ethanol.
If there is 87 without ethanol, I would like to track it down to see if there's any empirical evidence resulting in a difference in fuel economy strictly due to the grade of fuel, as the variability of ethanol would be eliminated and any increases should be as a result of the higher octane of the fuel.
Unfortunately, for most of the stations I frequent, I always see the "up to 10% ethanol" for the regular gasoline, hence, I just skip it and go to the premium fuels as the bump in fuel economy is often worth it for the increase of time & distance between refueling to offset the difference in cost.
