What to do with old gas?

[Nufy]

Any protests happening soon ???

J/K... Really I am kidding...

Related question: is there any danger attached to storing it for too long? I have an old mower which I use the gas on, but honestly I have no idea how long this particular jug of gas has been around. It seems to last forever! It only goes in the mower, and I only mow rarely (type of grass doesn't require regular mowings). It seems wasteful to toss it.

I filled my 5 gallon lawnmower jug two years ago.

Still going strong. No stabilizer.

The mixed 2 gallon for my chainsaw longer than that ago...

I wouldn't use old gas in a high performance engine requiring 89 or 91 octane, but any yardwork stuff is so low compression it doesn't matter. I buy Shell V Power 91 gas even for yard stuff because it doesn't have ethanol and won't gum up carburetors if they sit for 6 months or more.

Nope, you're wrong all gas contains up to 10% (minimum 5%) ethanol
It is a required by law.

There is no benefit to burning premium gas on an engine not specifically tuned for it, in fact it will likely adversely impact performance. Sounds like you have become a victim of good marketing.

I’m going with what the Gasman says on this topic.

Shell V-Power® NiTRO+ Premium Gasoline helps keep your engine running like new* with:

• Four levels of engine protection against gunk, wear, corrosion and friction
• The highest octane of all Shell fuels at 91 octane
• The highest concentration of the Shell Nitrogen Enriched Cleaning System
• Seven times the minimum amount of cleaning agents required by federal standard
• 0% ethanol at every station in Canada

Currently, Canada’s federal renewable fuels regulations require fuel producers and importers to have an average ethanol content of at least 5 percent based on the volume of gasoline produced or imported. The federal regulations also require 2 percent renewable content based on the volume of diesel fuel and heating distillate oil fuel producers and importers produce or import.

I wonder if this means they can get around it by averaging with regular fuel sales? I also only use it for my small engines. My lawnmower was super frustrating getting clogged every spring until I switched.

Oh, and here is a site that lists ethanol free gas, if yo want to track some down:

Not sure how they get away with it, frankly I am not about to dig into regulations, but I found this information from the Government website (which does say some exceptions), as well as petro-canada, which would indicate that 0% ethanol is not a quality of premium gas, although based on your post it is potentially a feature of at least one specific brand of gas.

The Renewable Fuels Regulations require petroleum producers and importers to have an average 5% renewable fuel content in gasoline and 2% renewable fuel content in diesel fuel and heating distillate oil, for each compliance period. There are some exceptions. The regulations include provisions that govern a trading system of compliance units. The regulations also require record keeping and reporting to assist in verifying compliance.

Yes, all of our grades of gas, including our Ultra 94 high octane fuel , contain up to 10% ethanol content. This is required by federal and provincial regulations.

Full disclosure my username has no relation to gasoline, it is reference to a previous career when I worked at a natural gas processing plant.

Total gas pool must be 5% ethanol, so they blend a higher percentage into regular and mid grade. Petro and the others use ethanol in 94 as a cheap octane boost, since E100 is like 105 octane.

Some gasman you turned out to be.

I looked it up (because I was curious). Fuzz is right on it being based on total fuel sales.

Because the vast majority of people buy 87, which contains 10-15% ethanol, that basically ensures the average hovers around 10%, even when some people are buying 0% ethanol NITRO or whatever.

So, not all gas has to contain ethanol. But all fuel sellers must meet the minimum regulation by total volume.

And not all premium gas contains 0% ethanol, only specific brands.

I was wrong that all gas contains ethanol, I was mislead by PetroCanada's assertion that it is required by regulation, and the fact that all their gas contains ethanol.

Aviation gas has no ethanol- told to me by a man who is anal about his gas.

WAAAAY too much information.

[burn_this_city]

AV gas had lead in it, can't run it in cars.

...And he was wrong
0% can be bought and it is way better for your carb in mowers ect.

I was wrong that all gas has ethanol. The other poster was wrong about premium not containing ethanol. (Only specific brands of premium).

I've never had an issue burning regular or old (stored over the winter) gas.
