RV Fuel Stabilizer Tips For Generators
Fuel Stabilizers and Gas Generators
Here’s an important tip for the many RV owners that use an on-board or stand-alone gasoline generator.
Today’s gasoline fuels are a blend of other added compounds. The one we’re concerned with is ethanol (commonly referred to as ethyl alcohol). Ethanol is drinking alcohol more commonly referred to as “booze”.
Most of the ethanol added to the gasoline supplied to our gas stations comes from our nation’s vast reserves of corn. The ethanol in our cars doesn’t typically cause a problem because we drive them every day continuously providing a flow of fresh gasoline. But when left standing for a short period of time (2-3 weeks), the natural oxidation process breaks down the alcohol and separates it, leaving a layer of water and an odor that smells much like varnish.
Unfortunately, our engines can’t burn water so they won’t start when this process occurs. In a small engine, like an RV generator, the separation process occurs quickly and will destroy (varnish) the carburetor. Today’s carburetors are not made to be rebuilt. They are “remove and replace”, creating a moderately expensive repair bill for something that is preventable.
Here’ your tip!
If you are putting your RV in storage and there is a way of cutting off the fuel supply, run the generator until it runs out of gas, thereby emptying the carburetor bowl of fuel that could contaminate.
If you can’t cut off the fuel supply, you must add a fuel stabilizer like “STABIL” to the gas tank. Be sure to run the generator long enough to be sure the carburetor receives stabilized gasoline.
This is the same procedure we use to prevent fuel separation and water buildup in boat and lawn mower engines. Follow the instructions on the bottle.
Most fuel stabilizers protect fuel for 12 to 15 months. This simple tip could prevent a costly and untimely repair to your generator.
