Fuel Stabilizer Buying Guide

Good quality fuel or gasoline should remain stable almost indefinitely. This will only happen if the fuel is stored well and is of a good quality. The best storage of gasoline is in an airtight container in efforts to prevent oxidation or mixing with water. The temperatures should be cool to reduce the chances that the container will leak. Well, these are conditions that are difficult to achieve especially because the fuel that you want to protect is in the gas tank of a vehicle or any other motorized equipment that uses fuel.

When gasoline is stored in a poor state, solids and gums start accumulating and this is what leads to what is commonly referred to as ‘stale fuel’. The existence of these materials in the fuel tank, the fuel lines, fuel injectors or fuel carburetors in older vehicles can be detrimental to your vehicles. The impurities will make it difficult for the engine to start and if it does, it will under perform and have a compromised fuel consumption level. Fuel stabilizers are used in extending the life of fuel that is to be stored for longer periods or will not be stored under the recommended conditions.
