As the weather gets warmer, a lot of folks are bringing their motorcycles, classic cars, and lawn equipment out of storage for the spring and summer seasons.

…Which can mean getting these sleepy engines fired up for the first time after hibernation may be tricky.

That’s because fuel degrades in storage over time, even over the course of just a few months. Not only can it form varnish and residue that might gum up a carburetor or injector, it pulls in moisture that may rust fuel lines and the tank from the inside out.

And the impacts of long term engine storage can be even greater due to today’s ethanol-blended fuels that have a knack for degrading rubber and eating away at seals.

That’s where a good fuel stabilizer comes in.

To show you exactly how fuel breaks down over time and some of the hazards of long-term fuel storage, we came across this video from the fuel additive aces over at Seafoam. Seafoam’s been in the fuel game since the 1930s, so its experts know a whole lot about the chemistry behind gasoline and related fuels.

The film is less than three minutes long, yet packs in a ton of good information about fuel stabilization—and how it can help prevent damage (and frustration) from the effects of bad gas.
