Fuel stabilizers are additives placed in gas tanks to prevent gumming and varnish buildup in gasoline or diesel fuel, keeping it fresh and usable for more than a year. They avoid the need for draining fuel from a vehicle before storage.

Fogging oils keep engines from drying out while stored. These oils inhibit corrosion by coating metal components and cylinders to stop water buildup. They can be used in any vehicle with a gasoline engine.
