Gasoline Explained
Gasoline with no ethanol blended in. It stores longer and is easier on small engines. Here is who should be running it and why.
Most pump gasoline carries a percentage of ethanol. It is fine for cars in daily use, but ethanol has two habits that cause problems: it absorbs moisture from the air, and it breaks down faster than straight gasoline. In an engine that sits, those habits turn into gummed carburetors, water in the fuel, and hard starts.
Ethanol-free gas skips all of that. No ethanol means it stores longer and runs cleaner through the small engines that suffer most from blended fuel.
Storage is the whole argument. If the fuel goes in and gets burned the same week, ethanol blend is fine. If it sits, ethanol-free protects the engine and the fuel both. The longer the gap between fill and use, the more it matters.
If you run small engines, standby gear, or anything that stores fuel between uses, tell us and we will help you decide where ethanol-free is worth it. We deliver gasoline with the right blend for how the fuel will be used.
