Texaco gas station. 100% premium gas 24/7, 7 days a week. Restrooms open during General Store hours. Our winter diesel is #1 winter grade and ordered especially for Idaho/Montana’s arctic winter climate and contains antifreeze agents. Typically good up until at least -30 fahrenheit. IT IS MORE EXPENSIVE than the cheaper diesel in the valley but it is #1 diesel mix with additives and costs us a lot more so please don’t ask why our diesel is more expensive than what they sell in Idaho Falls. It is worth it and it would be irresponsible of us to sell #2 up here in the winter. For Last Chance General Store hours just google “Last Chance Store Island Park”. Thank you!
