Ok. Been toying around with the idea of buying a small supply of Sunoco Optima 95 for use in small engines that see very little use over the course of a year. It advertises a shelf life of several YEARS. So... I live in the middle of nowhere and of course it's not available but there's a shop that'll sell me Sunoco Standard 110 octane leaded gas. Similar shelf life. Keep in mind. NO VP gas in my area. The ONLY thing available is the Sunoco 110 Standard. Economically there is not another viable option. (Shipping is a thing and gas is not only heavy but a hazardous material) This will be for a pressure washer, to sit in the generator, for who knows how long it'll sit before I need it again, 2 stroke gas, and a few other small engines that might get used frequently in fair weather but not for long periods of time. For example. I'll get my pressure washer out on a weekly basis but It's unlikely that I'll burn more than a tank a year on it. Two at most. Then it sits for another winter. Do you know how little fuel a Stihl weed eater uses?! Curious on thoughts?
