| Gav, there are a few with 91. It's just that in most cases it means they must have an additional tank, so many stations can't do it. My favorite gas station, which was one of the cheapest yet still self serve (an unheard of combination around me--I hate full serve but eat it to save the coin) also had 91. One week after buying my mini, it closed and was replaced with a dunin donuts (that other liquid that is way more expensive than gas). It's very rare I get to put in 91 now.
Did everyone notice the gas prices jump overnight? remember bostongasprices.com if you're filling up... |
