It is common knowledge that time deteriorates fuel. The shelf life of gas can range from three to six months. Long storage of gas causes gums and furnish that adversely affect the fuel system. Through time, exposure to heat, and pressure, fuel can become stale and put intrastate. Using old gas is also detrimental to your engines.
It can damage your equipment and can cause fuel-related downtime. To avoid this problem, a fuel stabilizer is vital in engine care and maintenance. A fuel stabilizer is an anti-oxidant that increases solvency, breaks down varnish, prevents oxidation, protects from corrosion, and restores performance.
A fuel stabilizer is crucial in small engines, especially lawnmowers. Using a fuel stabilizer is the easiest way to maintain your lawnmower for the seasons to come. It ensures mowers run quicker, smoother, and without difficulty.
Considering the foregoing, we looked for high-quality additives to prevent engine degradation. The products discussed below boil down to similar features: promoting power, better fuel economy, and ensuring a year or two of safe storage.

Fuel Stabilizer For Lawnmower – Buyer’s Guide
Now that you have learned the feature, benefits, and drawbacks of our handpicked fuel stabilizer, there are specific considerations before purchasing one.
Although fuel stabilizers are designed to save fuel, protect engines, and improve the performance of the equipment, you cannot have your desired result when you purchase an additive that is not compatible with your fuel. An additive may be compatible with gasoline but not with diesel or ethanol blend or vice versa. Thus, it is essential to know first the fuel you are using.
Ease of use
One of the most important considerations is how easy the product can be used. We use additives to make our chores more straightforward, more convenient and have peace of mind. This includes the product design, how easy it is to measure, pour, and apply.
Length of Time
The idea of a fuel stabilizer is to increase the shelf life of fuels. Some fuel stabilizers prolong the shelf life to several months, and the best ones can increase the shelf life by up to 2 years. Hence, it is essential to know how many months can be stored while retaining their strength and freshness if you are storing numerous fuels.
One of the primary reasons why an engine deteriorates quickly is through too much water absorption. A fuel stabilizer that contains alcohol will make this a more significant issue and fail to correct the problem of the engine.
Some fuel stabilizers are more concentrated than others. An ounce of a fuel stabilizer may correct several gallons of fuel while others can correct fewer gallons. Thus, it is also essential to consider the ratio of the fuel stabilizer and the gas because a consumer can save more in the long run.
