In-Tank Fuel Stabilizer Filter (2-Pack)

Fuel Life In-Tank Stabilizing Filter, to good to be true? That is the question I have been unable to answer definitely. Full disclosure: I have been provided with a sample two pack for 1 – 5 gallon fuel tanks for review. This review is my honest opinion and has not been influenced by the free sample. I have no connection with the manufacturer B3C and have not been provided with any other compensation. All that being said I am a true believer in fuel stabilization for gasoline machines which are not used on a regular basis. For me that includes two pressure washers and an outboard motor. I also own a couple of chain saws which I don’t use any stabilizers because they are so tempromental. I drain their tanks and run em dry after every use. Pressure washers and outboard motor are ideal canidates for fuel stabilization, because it’s not rare for me to let them sit unused for months and they are difficult to drain. The thought of putting a filter in their tanks that will last up to 2 years seems almost to good to be true, so I started my less than exaustive lititure review. I visited several internet sites of fuel stabilizer manufacturers. None provide an ingredient list. Apparently they guard their “secret sauce” resipie closely. This makes it impossible to choose a stabilizer based on chemical composition. These In-Tank stabilizers appear to contain some sort of whitish inorganic crystals. Without doing any actual analytical experimentation it’s my best guess that they contain a calcium-zinc salt which is a common ingredient in gasoline stabilizers. So what I’m left with is, as I have mentioned, a belief that fuel stabilizers actually work because they are frequently recommended by manufacturers of gasoline engines. Having reviewed this manufacture’s website I was left moderately impressed and think it’s a good bet that their chemists know what the heck they are doing. The last question I wanted answered was how to know when the filters require changing. The package says they last 1 – 2 years. I sent a request via the manufacturer's contact us weblink. After over two weeks I have had no response. So in my final fly by the seat of my pants opinion I’m excited to give them a try. After 18 months I will remove one for a gross postmortem. Time will tell if my carburetors get clogged up and I think it worth the risk because I have trouble remembering to add liquid fuel stabilizers and these may be the answer.

This product Fuel Life seems to be a good solution to stabilizing gasoline in small engines. I have been using a liquid stabilizer in my gas cans for a long time. With those I have to measure precisely the amount needed per gallon every time I fill the cans. With Fuel Life I just drop the filter into the gas tank pour in the gas that hasn't been treated and Fuel Life does the rest. I will come back to this review when and if something went wrong however, I believe it will work.

I got this fuel stabilizer because I store extra fuel for my equipment (riding mower, push mower, portable backup generators, engine driven water pump). I would like to store larger quantities and have it last longer so I need to add a stabilizer to make it last. This kit claims to stabilize fuel for up to 2 years and remove water. I know there are other fuel stabilizing additives on the market that interact with fuel on a chemical level to prevent it from changing composition and becoming ineffective for combustion, but what I found interesting about this product is that it claims to physically remove water. Nothing on the package or their website lists any sort of active or inactive ingredient, but there is some sort of substance inside the white filter cloth material. So how does this filter remove water, which is hydrogen and oxygen, from a closed container of gasoline? From my experience with military aircraft, water is drained through a sump in the bottom of the tank until the water is gone and fuel starts to come out. So then how does water get in fuel? As some of you probably know, fuel will float on top of water when the two are mixed. Since most fuel systems draw fuel from the bottom of the tank to send it to an engine, water in the tank would get sent to the engine causing the engine not to run. Water gets in fuel primarily from condensation during temperature changes, but may also be introduced in other ways depending on your location and storage method. Bottom line, you do not want water in your fuel. So, to try to see how (or if) this works, I set up a test where I put 2 inches of water in a mason jar, filled the rest with fuel (87 octane) and installed one of the two stabilizing filters from the kit. I marked and measured the water level on the side of the jar and closed the lid just as you would close the cap on your fuel tank. I checked the jar after 12 hours and found there was no change in the water level. The only noticeable difference was a couple of bubbles had collected next to the part of the stabilizing filter that was submerged in the water part of the mixture. Not sure, but it appeared to be air escaping from the filter element. I opened the lid to vent the jar then closed it again. After 24 hours, it looked the same, with no change in the water level. While I did not expect to see all 2 inches of water removed, I was hoping to see a measurable decrease in the water level that would indicate this product works. Unfortunately I saw no indication that this will remove water and I do not recommend this product for this purpose. Since the manufacturers packaging and website doesn’t say what’s inside the filter element and how that substance is supposed to work, I can’t recommend this for any purpose.

I often have issues with water developing in my mower and other small engines of tools that I use. I am currently giving this 5 stars since I believe that this product will do what it promises. Since it is supposed to last for 2 years I can't review at that stage. This is really easy to use. Open the gas tank and drop in the filter. You should run the engine for 10 minutes to make sure the treated fuel gets into the carburetor. This should solve issues with water in the tank and help filter out impurities. So far I have put these in my snowblower, tractor mower, and push mower.

Got this product to reduce the risk of contaminants and water fouling up the small engines on my Ryobi weed whipper and Echo blower. Directions say the filter can be tethered on a line for ease of removal but I did not want to use that method thinking it would damage the fuel cap seal and cause fuel to leak out when maneuvering the tools. Instead I will use long tweezer to remove. The filters are fairly large and should last the maximum 2 year recommended utilization period. Being large they also take a portion of the fuel tank capacity which is low on these two machines anyway. Time will tell how well they work in conjunction with the fuel filter on the unit to prevent contamination from entering the carburetor.

This product is very easy to use and is very convenient. I put it into my snowblower has tank so I can't say how that will work out right now. I loved the fact that you only need to use it every other year and it comes with a tether and tag to remind you when to change it out. It is meant to keep your gas stable and is much easier than having to add stabilizer yearly and the mess of pouring it into the tank .

I initially thought this was for vehicle, but it's for lawnmowers & other gas powered tools. It seems to do the trick. Only time will tell how this helps. It's definitely better than not having anything at all in your gas powered fuel tank. The only thing missing is a string. You could possible attach some twine or dental floss to help remove the filter once it's at the end of life.
