I always find the differential between mid-grade and premium gas fascinating too. Between brands, the percentage difference in price can be all over the place.

Since I've tuned my car to run on high octane and I'd prefer to avoid ethanol, my fueling options are somewhat limited. So I try to avoid looking at the price per litre when I trundle down the hill to the Chevron.

My attitude of passive denial might change when our office reopens. Since being packed in like sardines on a train for 40 minutes is not exactly appealing to me right now, I may end up driving to downtown more often.
