Seasonal equipment owners, this is one of those products you don't think you need until you've dealt with gummed-up carburetors from old gas! This CRC Fuel Stabilizer in the handy 1-gallon size is perfect if you have multiple pieces of equipment or need to treat lots of fuel at once. Made right here in the USA, this stuff works wonders for keeping gasoline fresh during storage. If you've got lawn mowers, snow blowers, boats, motorcycles, or generators that sit for months without use, this stabilizer prevents the fuel from breaking down and forming those nasty gums and varnishes that clog up your fuel system. Just add it to your gas can before filling up, or directly into your equipment's tank, and run the engine for a few minutes to circulate it through the system. It also helps prevent corrosion in your fuel system and keeps the fuel from oxidizing. The 1-gallon size is super economical if you maintain several vehicles or have a farm with multiple pieces of equipment. Much cheaper than dealing with carburetor cleanings or fuel system repairs down the road! I use it in all my seasonal equipment - the lawn tractor, snow blower, and backup generator - and everything starts right up even after sitting all winter. Seriously, if you value your equipment and want to avoid expensive repairs, this fuel stabilizer is absolutely worth it. The gallon container has a good pour spout too, making it easy to measure out what you need without making a mess.
