Lots of Shell here in SC, and I am a sucker for their advertising, esp for their purity and maybe less valve deposits, and in our newer cars and my QV only the 93 octane. In my '52 army truck, with a flat head 6 cy, and my power products, only non-ethanol gas. I try to not let my fuels get too old, and use Stabil in my gas cans and truck. And I don't use gas for cleaning parts. Too dangerous. Long decades ago, my brother in law, then a teen, had a gas tank he was welding on explode, and he spent the next six months in a burn unit. And back in the early '80's, my beloved Huffaker Racing prepped TR8 had a gas leak, and the garage hot water heater's pilot light blew it up, burning my TR and the garage, and only the firewall between the house and the garage saved our home. I am very very careful with any fueling I do.
Be safe out there, NV
