Gas also loses its viability over time if there was no fuel stabilizer used. Maybe you should check before using it. Im not sure on how to do this you may have to look it up or maybe someone else knows.

yup...i rotate my gas every year.
just so happen my 5 plastic gas cans need to be rotated. 🙁
was not taking age into consideration......y can i not lift 150 Ibs over my head any more 😯
must be fukushima

okay good ...well its good to know ...really never thought of that aspect....i wonder how often they should be rotated?

i rotate every 6 months. ive learned from my work experiances that gas sitting more than six months without stablizer. turns to crap. not litterally of course but it doesnt burn as well as it should. cause's a bit of spitting and sputtering in a vechicle engine.

Excellent Fuel Stabilizer... PriG for gasoline and PriD for diesel. Better than "Stabil"... lasts much longer and you can "refresh" year to year.

Gas is usually good for at least one year if not two. I have stabilizer but I only use it in the tanks of rarely used vehicles. Generally a 5 gal can if full and stored well will last a couple of years. Also depends on the engine you are using it in though . Always date your backup supply. Just rotate your supply and it will be fine.

so what do you do if you have "bad gas" in a lawn mower

I rotate gas every six months too. It may last longer, but starts to deteriorate after months.

Also keep a siphoning pump on hand. They are relatively cheap and easy to store in the vehicle. Great to use if you need gas in an emergency, and there are other abandoned or derelict vehicles.

Gas Lawnmower? 🙂 Havn't had one in years! Go manual! Toss it out! They make there money back in a couple of years on what you save in gas/electricity. and the new models out are not like the old ones from the 70's! Easy to use and very efficient!

I use the Canadian Tire brand stabilizer in my gas storage. Once a year I dump that gas into one of my vehicles then store fresh gas with the stabilizer. I have never had a problem that way. Older gas could probably be used in the lawn mower with no real issues. If small engines are sputtering and such, most likely there is water in the gas from condensation. Also, small engines tend to be difficult to start after sitting a while. One trick I love to use to start these engines is to pour a bit of gas on a rag and put it over the air filter, or replace the air filter with the rag. This gets them up and running in no time, every time.

As I will be renting a post hole auger sometime in the next week or two, I think I'll be using some of my older gas in that...

Canadian Tire and Home Hardware both sell just the replacement can funnels.

When I went to trade school for auto service (what they call mechanic now) we learned that modern gas has about a month shelf life without stabilizer added, according to the fuel distributor association. Now, I have had unstabilized gas in a can for a summer and into the fall and it still worked fine. If I suspect that I'll be storing something for more then 3 months, I'll stabilize the fuel for sure.

Old gas or bad gas in a tank can be siphoned out or removed (I take the small gas tank off, disconnect the fuel line and let the gas drain into a container myself) and usually if new gas is used the engine should just go. If there's not a lot of the old gas in the tank, it's okay to put in new gas and mix it up and try it. Usually works. If the gas has been in there for a long long time, say 3 or more years - then your gonna need to remove the gas for sure and probably strip down some parts to clean them out...fuel lines maybe replaced and the carb cleaned out (great time to replace some gaskets and stuffz too with an inexpensive carb rebuild kit).
My lawnmower has been an experiment of mine. I got it for free almost 10 years ago. It was almost 6 years old then. It's just a 3.5 horsepower...but it runs like a champ. I've had to do some very minor maintenance on it - replaced a wheel and I need to replace the side discharge shield soon. I've abused it a little bit...one time when I lived in an apartment I never touched the lawnmower for almost 2 years and forgot to take all the fuel out of it. When I needed it, a little clean out, a new carb rebuild kit ($20 for my model), some sanding of the magnets and a new spark plug and I've been using it since.
This sort of thing applies to snowthrowers. I got a 5 horsepower snowthrower for free about 9 years ago because it wouldn't run. Tore it down, cleaned it out - the fuel had sat around in it for years and turned to varnish - and now I firmly believe shoveling driveways is for suckers 😉

Have you used this ? I have seen it and wondered... I know that when I stored my ATV in October, by april the gas was fouling the plugs and wouldnt start the machine, so I am gonna need some stabilizer this year. 😀

A trick to be learned about sparkgap on 2 stroke engines. Get a piece of thin metal and file it down to the specified sparkgap and chain it to your motor somewhere, so, that when you need to tweek the engine you wont use the eyeball gauge and a screwdriver on the sparkplug.

Hi mason. Yes I use this product and find it excellent. I also use Stabil but only for fuel that I plan to keep less than 6 months. Pri products are more expensive but well worth the cost. You can use this once a year for more than one year so can effectively store gas for 2, 3, 4 years. I have never had a problem when I have used this.
