Using A Fuel Stabilizer To Extend Life of Gas

Does Fuel Stabilizer Work | PRI-G Fuel Stabilizer

If you own a gas power tool that has been stored for some time with gas in it, you probably experienced some engine starting problems when trying to crank it. Gasoline over time gets old or stale and some of its properties breakdown causing some gum and carbon deposits to build-up causing the gas to get stale and goes into the carburetor causing starting failures. Does fuel stabilizer work when added into the fuel tank? The answer is absolutely yes.

You just wont believe it when you add the stabilizer into the fuel how it can extend its life and your gas powered tool will start every time. Not only do they keep the gas fresh longer, they also can help protect the life of the engine over time as an added bonus. Most stabilizers extend the life of gas in storage for up to one-year. The following topics that will be covered are listed below.

Recommended Stabilizer Rankings

If we had to rank the fuel stabilizers in order from one to five our listing is below:

1. PRI-G – Our reasoning for this ranking even though it’s the most expensive of the five, this product is good for up to three years when opened, the best of the five. You can extend the life of the fuel with annual treatments, which you cannot do with the others.

2. STAR TRON – This product is the second most expensive you get 16 gallons of treated gas per ounce which is tied for first best. It provides 2-years of fuel stabilization once placed in the tank, the second best.

3. BRIGGS & STRATTON – This product provides up to 3-years of fuel stabilization once placed in the tank. The best of the five.

4. STA-BIL – This product allows you to extend the life of the fuel by doubling the dosage rate for up to 2-years.

5. STAR BRITE – Provide Ethanol protection for E10 fuels for 1-year. Back to Does Fuel Stabilizer Work topics.

Conclusion

I think you can agree that all five of these products will do the job for preserving gas for up to 1-year. However, each brand has its own best options. Our recommended brand is PRI-G for the reasons stated above. The bottom line is to provide protection of fuel once placed in the tank of any gas powered tool. The tools include: lawn mowers, generators, leaf blowers, snow blowers and even the engine in your automobile. Back to Does Fuel Stabilizer Work topics.
