[Princess Auto] Fuel Stabilizer $3.99

It's that time of year again - in prep for storing my Mazda Miata and my lawnmower for the season I did a quick search for a deal on Fuel Stabilizer.

Princess Auto has 350 ml bottles on sale - much less expensive than CT/PartsSource/Amazon/HD/Lowes etc.

Are all fuel stabilizers made the same and do the same purpose regardless of brand, etc? Need it for my lawnmower.

Fill your tank with NON ETHANOL premium gas and fuel stabilizer.

Apparently even Shell is converting to all ethanol based fuels including the supreme blend due to government regulations according to a different RFD thread. Might be hard to get this kind of fuel in the future unless you know a source

I think the best way to store lawn mower or snow blower is to let it run and burn all the fuel and store it empty

Ethanol or not shouldn't really matter too much as long as you dont let the fuel sit in your machines for too long. That's the key, only put enough gas in to do what it is needed for that job at that time that way you don't have gas sitting there for a week (I cut the lawn once a week) or until the next use. When I winterize my lawnmower, I drain all the fuel from it, fill my tank about a quarter way (yes I know it's excessive, but better to be safe than sorry) with just fuel stablizer, flush it through the lines and that's it. Same with my snowblower, pressure washer, etc and I have never had a problem getting them to start back up in the spring/fall after them sitting for months.

You can do that + add fuel stabilizer and flush it through the lines by pulling the pull cord 5 to 10 times and that's it

I think the video largely answers that question although the best thing you can do for your lawnmower is to run the engine to use up the remaining gas so it's dry going into storage.

Alternatively this is the next best solution to winter storage. I use regular ethanol gas throughout the summer and then in late fall switch to premium non-ethanol with Sta-bil fuel stabilizer. I have in fact just done this as I head towards the last couple of mowings before the snow falls.

Good video incidentally.

Yeah I usually put Shell 91 and fuel stabilizer in a fill if something is going to sit for a few months or longer.

I have a love/hate relationship with ethanol as my subaru is flex-fuel tuned and runs on both E85 and Shell 91.

Ethanol can produce incredible power in small forced induction engines, I run E85 in the summer and the engine puts out an additional 40 whp over Shell 91.

But it gets unusable in the cold and can gum up the injectors if gasoline is not run through every few tanks. Lose all that vroom vroom in the winter.

No that easy to do on my 72 Buick, with a 95L tank :(

Ethanol is just a pain in the @ss for in carb based equipment. The water absorption properties of Ethanol, make it corrosive. The corrosion issue is most detrimental in carbureted vehicles, where critical carb components are made from die-cast aluminum or zinc (which will corrode when stored) :(

Yes in vehicles you need non ethanol fuel, but I am referring to small engines like a lawnmower or snowblower. What I said above still applies to small engines. I have done this method for many years without fail

Yes.. For small engines, agreed.

I had my Craftsman mower for 23yrs, and in the first decade "when I didn't know better", I would use regular fuel, and just leave less than 1/4 tank of fuel in tank, add more than double amount of fuel stabilizer than recommended, run it for a few seconds to get it circulating into system, and then store for winter. Spring, I would top up the tank with fresh fuel, and never had an issue starting it up with 2 or 3 pulls. 2 weeks ago, it died (I think it blew a valve - will open up during winter and check it out), but nothing due to fuel..

My nearly 40 yr old Toro snowblower, was treated the same, and never had an issue starting it. Still works like a charm.

You can't use all the fuel even when its "dry".

The carburetor bowl always has fuel in it. Unless you drain that as well, doubtful the majority of people actually remove the bowl.

Hence why it is good to use fuel stabilizer.

Good deal.

However, I have a few cans of Seafoam I need to use up for my Snowblower.

Fuel stabilizer also goes bad after a couple of years when exposed to oxygen. So i always have to buy a new bottle everytime i use it to store my motorcycle off season

I have a Gas scooter and gummed up the carb once while storing it with fuel. I'm not mechanically handy to drain tanks so my friend who is a mechanic said you can store it all winter with fuel so long as it's ethanol free. I've never winterized my small engines in years following his advise and so far no more gumming of engines. Sometimes I'll do that with the stabilizer. Draining the tank as you mentioned would be far more effective I'm sure

I guess I could drive it until 0 fuel remains and let it just die out, same end result. (Oops someone above just said that won't drain the carb of fuel)

I know I'm gonna start an argument, but... ;-)
I've lived on a rural property for 20 years and have about 10 small engines. I've never used fuel stabilizer and never had a problem.
I had a push mower from when I lived in the city. Now this was a bullet-proof, reliable mower. This mower is the reason they tell you to disconnect the spark plug when servicing the blade, cuz it'll start :-0. It sat for about 12 years (no use for it in the country). Someone I knew needed a mower, so I put a little gas in it and went to start it. I'd like to say it started on the first pull. Rather it started on the first HALF-PULL! BTW - when I bought it new, as a true RFd'er, I had selected the cheapest no-name mower I could find.

I have a 2-cycle weed whacker. Again, in the country it gets used very little (not like I'm manicuring a city lot). I finally used-up the 5l of gas/oil mix that I mixed about 6 years ago.

Also, as a cheapo, I've purchased used motorized items (tillers etc). I get 'em cheap cuz they don't run. I clean out the carb and fuel system and get them back running. I dunno what the previous owners are doing to get them gunked-up...maybe using fuel stabilizer ;-)

Anyway, my experience.
