It seems that I remember that the price difference between gasoline grades was usually 10-15 cents a gallon, even when gasoline got up to 4 bucks a gallon a few years ago the price spread did not seem as great as it is today.
I filled up yesterday and noticed that 87 octane was 2.39 a gallon, 93 was 3.04 a gallon.
This was at a Top Tier station, Shell, and all grades here in the corn belt contain 10% ethanol, except at a handful of stations. I wondered why this has changed.
I have one vehicle (3.3L Toyota)that does not require premium fuel, but can benefit from it. I typically only put premium in it when I have driven in the mountains, was doing heavy (heavy for the vehicle, 3500lbs) towing or when I have simply felt rich that day.
It does make a difference in power, a slight difference, I have read between 15 and 20 percent.
More curious than anything, I have had the impression that the additive package is the same between the grades at a top tier stations?
