I usually have leftover 2 cycle fuel between seasons and don't want to hold it over until next season. I was thinking about using it in the lawn mower since it does not have a CAT and maybe mix it 50% with fresh fuel. I want to dispose of the fuel in a responsible manner.

I think that in a sufficient dilution you could run it in almost anything. I'd stay away from the finer emissions systems but even they might not notice it once completely combusted. One gallon of mix is worth $?

I have been using it in my Tacoma but I don't want to ruin the CAT. Not sure if it matters.

I am no expert on 2 cycle oil mix, I wonder if they have any additives that are nasty to cat. Add some stabil and use it next year Or send it to me I can run it in old things

OK I will send a mayonnaise jar full
Had to use spell check to spell mayonnaise

The addy is Under Funk & Wagnall's Front porch, Staten Island. NY

Most small engines that require gas-oil mixtures now call for 50:1. 40:1 used to be the norm, but the they've lowered it to improve emissions, if not necessarily improve lubrication.

The local Sthil dealership tries to sell a six-pack of "2-stroke" oil with every purchase. One bottle is enough to treat one gallon of gasoline. I did some quick math and determined that a six-pack would hast me about 100 years. My neighbor wasn't so smart, and she bought the six pack. Her husband is too much of a knucklehead to mix the gas and oil properly, so he started buying the pre-mixed stuff. He gave me five unopened bottles. I gave two bottles (worth about $5) to a landscaper who works in Bubba Estates, and kept three.

I have a Stihl edger and hedge clipper that use gas-oil mixture. But, they're both 4-strokes.

The "2-stroke" oil probably contains ZDDP, which is a great anti-wear agent, but it harms catalytic converters. They've stopped putting it in motor oil.

The more you dilute it with pure gasoline, the better off you'd be burning it in something that doesn't take mixed gasoline-oil. You risk fouling your spark plug, but no more so than it would in an engine that uses mixed gasoline and oil.

Non-ethanol gasoline is readily available in Bubbaville Beach. Bubba buys the stuff 100 gallons at a time for his boat. The Mobil station across the street from Bubba Estates sells the stuff out of one of their main gas pumps. I can use a credit card and not even have to go inside to pay. I buy less than one gallon at a time, and I make a point to burn every drop of it within 30 days before I buy more.

At the end of the growing season, I put every one of my gasoline-powered implements of destruction on my driveway, start them up, and run them dry. That pisses of some of my neighbors, especially the guy with a Tesla. OFW.

I run 32:1 lawn boy mix in all of my stuff. 2 stroke &4. No issues in over a decade .

I also run the fuel out of any implement before storage. My Echo trimmer is at least 15 years old and runs perfect. That's the last 2 stroke yard tool I have. And now the moped. They both call for 50:1 so they can share the fuel.

A friend of mine had a moped store and repair shop in the 1980's. People living under the RADAR used mopeds as their primary mode of transportation, and they'd wear out the engines. Switching to synthetic oil greatly extended the engine life.

My friend's largest customer was the city's drug kingpin. He'd buy a dozen mopeds at a time, and had kids riding them moving drugs cash around the city. The moped engines lasting longer on synthetic oil lowered his operating cost, and he could pass some of those savings to his customers.... the city's drug addicts.

I carry a stopwatch when I'm operating my gasoline powered implements of destruction. My previous B&S lawnmower had 150 hours after 18 years.

My 23-year-old Honda string trimmer has 65 hours.
My nine-year-old Honda mower has 135 hours.
My eleven-year-old Stihl edger only has 20 hours.
My nine-year-old Stihl blower only has 32 hours.
My six-year-old Stihl hedge clipper only has 1.4 hours.

It's hard to wear out a commercial-grade gasoline powered implement of destruction in consumer use. The limiting factor is usually that parts are no longer available. Carburetors last about ten years. I had a hard time finding the "20 year" carburetor for the Honda string trimmer. So, I'll probably have to scrap it at 30 years.

My Honda mower is their consumer model, $500 nine years ago. The commercial verson was $1000 nine years ago. The dealer convinced me to only get the consumer model. He said a lot of landscape companies only buy the consumer models.

I tip my mowers on their front wheels before starting them. That sloshes oil up into the cylinder on the crankcase side of the piston and gets the rings wet before starting. That'd cause some start-up smoke with my old B&S mower., but not with the Honda.

I have some rogue trees growing up against the house. When the supply chain **** is over, I'm getting a fuel-injected Stihl chainsaw to deal with them, $700. One use will pay for it, like it did for that hedger clipper.
