Will They Start? Fuel Treatment Experiment
Vložit
- čas přidán 27. 08. 2024
- Taryl's long fuel experiment continues with another installment into March of 2021. He's letting these engines sit another month and will start them again next month (if they'll run). This time around he's going to attempt to run the inside and outside engines that have been sitting for 3 months. Will they run? Will the weather break them down after sitting? One is out in the elements and the other is inside the shed. Check it out here for another interesting fuel treatment video as we get to the bottom of what causes these fuels to break down and what preserves them. The quest continues... And There's Your Dinner!!

The engine's started every three months seem to run better than the ones started every month. I think your right about the snake oil theory
It’s probably conventional 10W-30 oil in the engines. In the winter it’s hell getting them started. I’d bet if the engines were 3years old broke in and 5W-30 synthetic was used they’d start easy like a snow blower starts easy in the winter.
@@NorthlanderMN you don't need synthetic in winter. I have a mid 60's ariens gard-n-yard with the snow attachment and the original engine. Never had synthetic oil in it and still starts 2-3 pulls mid wisconsin winter. Just regular maintenance.
@@meegstomtom Every engine brand combustion chambers, ignition, carburetor etc vary per brand and year.
But you are right about proper maintenance.
Tarly,my daughter loves watching every one of your videos with me.Yesterday she got her drivers license,I believe that you helping her understand mechanics had something to do with that.Thanks again for all you do.
Totally AWESOME boys!!!!
oh look its the other small engine channel i watch
Only concerned about the alcohol part.
You gotta love the Taryl "Stumblin Off-Choke Dance"! I wait for it every time!
I have never in my life used any type of fuel saver in any of my lawn equipment-- have never had a problem- I am 70 years old LOVE YOUR VIDS
Taryl: I think you just about hit the nail on the head with your "snake oil" comment regarding fuel additives. These gas manufacturers are very clever people and know everything there is to know about the fuel they sell. If an additive would make a big difference to a fuels performance they would be putting it in there at the manufacturing stage. Lubricant additives are a similar con trick to be avoided.
I agree, manufacturers know their product. The only time I use an additive (sea foam) is after I've cleaned a carb. I find if something sits for 2-3 years, the fuel here turns orange and soft "crystals" grow in the carb...could be the absorbed water allowing a galvanic corrosion of some sort that plugs them up. Anything that gets used, the fuel never gets that old.
I think after seein this one I’ve bought my last bottle of sta-bil
It's sure not looking good for additives. I guess the moral is: keep gas in a secured container, and you're good for at least a year and a half. Not sure how long Taryl wants to continue, but maybe Sta-bil et al does its thing after a couple of years.
I spent a month and a half repairing small engines at my dad's shop. And each day I watched one of your video's I learned so much! Repaired everything from single stroke to duel cylinder and up. My favorite was a Onan 2 cylinder fork lift had been setting for 20 years. With your help was able to break it down and rebuild the engine, carburetor, points, magneto, and a rusted old gas tank. Thank You so much for your video's, There's nothing like the feeling of fixing a broken device.
Whats a single stroke?
@@effgee5102 1 piston or cylinder
Those Subaru engines are pretty freaking good.. Left out in the weather for months in snow, they still fired up..
Additives may not be what they claim to be after all..
I bet the new style Briggs engines with the plastic carburettors and plastic fuel jets wouldn't have lasted this long.
@@bentullett6068 Plastic doesn't corrode.
People are crapping on Briggs for starting to use plastic in fuel systems, but automotive industry has been doing it for 40 years. Everything from fuel tanks, to fuel pump modules, to fuel lines, to fuel rails, to fuel injectors. All very much capable of lasting the life of an automobile.
@@erikj.2066 it's not the plastic that's the issue it's the main jet design. We have been told by Briggs and Stratton's UK operations that we must change these jets on a regular service. Issue is there are many people who don't look at the terms and conditions the manufacturer states and never service their mowers and expect them to last and work reliably, they wouldn't be told about the jets blocking in the carburettor if the fuel goes off and assume it's under warranty.
@@erikj.2066 And Intake Manifolds.
A couple thoughts-
"Premium" fuel does not equate to "Better"fuel.
"Octane" does not equate to volatility. It refers to how fast the mixture burns in the combustion chamber, and high octane burns slower than regular.
In some premium fuels no ethanol is added. It varies by state and gas stations.
Premium fuel labeled “No ethanol added” in my book is better fuel.
I appreciate all of the effort that goes into getting us this information. I refer my customers to this video series every chance I get. "It's Donut Time"
Only treatment to my fuel system is I treated it to the addition of a fuel valve. I shut off all my equipment from the fuel valve and burn the gas out of the carb before storage. Been doing this for years and it's never failed me. Mostly just have to jump start the first time.
totally agree
Works for me.
Absolutely! Been doing if for years and it works! I cheat on the jump start. I bought some of those cheap HF float chargers and put one on every vehicle and piece of equipment I own that has a battery.
I can't wait until Taryl debunks that theory too.
@@mark-wn5ek Dude, do you even know the definition of theory?
Dactacular video. Surprised those would run at all.
We need to see em sit for 5 months then watch em start.
Amazing. Just Amazing.
These newer engines have better sealing gas caps. Old engines have caps that vent both ways. kind of open like the open lid glass jars. Wonder if they left a cap loose for experiment how it would start over time.
The next video will be Taryl gets a new rotator cup replacement...from pull starting engines...lol....Fire it up ...Fire it up...Fire it up........ Shaddup !!
😂
I'm old! 3-4 pulls I look for a problem. Here probably the problem is the old fuel in the carb. I hope :)
That would be entertaining to ;)
Well, he could do change rules and start them with a drill like Mustie1 does
Rotator cuff was screaming🤣😂
HAPPY BIRTHDAY !!!!!!!!
Impressive. Difficult to believe that these engines are starting. I see similar conditions and the fuel is just rancid and no way will the engine start. Keep up the good work and thanks for the videos.
Last month's theory: fuel additives are snake oil
This month's theory: these freakin Subarus will start/run on anything
Hey taryl never realized your a lefty another Homer with this new video my friend this is for the entire crew God bless you and your family and there's your dinna
I've been saying since the beginning of this experiment that fuel additives are not necessary. For years and years, I've been wintering-over leftover 2/4-cycle dinosaur juice. Never had the slightest hint that they were unuseable from one mowing season to the next. For the first time since November, I started both my Toro weed wacker and Craftsman leaf blower with a lot less trouble than Taryl had. My (nearly full) 1 gallon 2-cycle dinosaur juice jug sits on the shelf. I'll be giving it a shake, then finishing it off, come springtime. My Craftsman YTS3000 Mower has been starting (twice monthly) throughout the wintertime with plain old 87 octane Corn Whiskey (Ethanol-blended Regular). My mower gas will be good enough to begin mowing season as well. Dinosaur Juice Fuel Additives are; SNAKE OIL, SNAKE OIL, SNAKE OIL!!! Another big help is, KEEP YOUR EQUIPMENT AND DINOSAUR JUICE CANS INDOORS!!!
Thank you.
Thank you!!!
Taryl awesome video buddy
Thank you for the video
I'm done thinking about additives.
I can't imagine how someone could logically explain to me how they are of value.
Thanks, Taryl.
The outdoor engine did well
taryl is a southpaw!!!
I was bragging that my mower, parked in the snow, would start fine come spring. It did but, the front-drive rusted tight. Oh, well. More work.
I had a brand new 15 hp Mercury 4 stroke. In the manual they mentioned nothing about draining fuel out of the carburetor. All the four strokes after that put a red screw to drain the fuel for storage. Now Mercury has EFI. My outboard had that white stuff in the carburetor. I didn’t know it was from the ethanol at that time. I just blamed the outboard as being fussy and hated the thing. Before that I never heard of using stabilizers. My dad never did ever.
From that point on I’m firm with using stabilizers in all of my engines especially if they’ll sit for months all winter like here in Minnesota. Nobody around here will ever start a lawnmower once a month after the snow falls. When its put away it’s put away.
Since that I’ve used SeaFoam. Last summer I switched to the Red Sta-bil. This summer I’ll be using the Sta-bil 360 Amber. The reason I switched is because Sta-bil is more economical and goes much further for the price.
Nice!!
it seems like cranking it gets the fuel in the carb out then the fuel in the tank starts it. Running the carb out of gas is a good idea. This confirms my thoughts about fuel stabizers being a waste of time and money
Keep going till fuel runs out.
I'm surprised that Subaru fired up, for 14 month old regular pump fuel in it, that's impressive.
Looks live Happy.
That is amazing, that they started
Spoiler alert.
Why spoil it
@@brianvassar2556 your supposed to watch the video before you read the comments lol
Wow its already been a month!
Ya,I say the same thing every time.Enjoy it people it goes fast.
06:58 Wow! Plain 7 octane stays good longer than duct tape! *That* is a scientific discovery my friend! 👍👌✌😄
Hey Taryl, maybe you should market your own additive, and call it, " Taryl Dactal's SNAKE OIL Fuel Treatment"! 😆😆😆
But you know what? I bet it would SELL!
I would’ve passed out pulling it that much
Best tune up for small engines...fresh gas.
Snake oil experiment 🧪 That's a good name for the test. I personally never used additives in any of my power equipment and never had any problems starting after put in storage for the winter. Great video as always thanks for sharing Taryl. Have a great week.
thats my birthday! hopefully it runs for ya!
I understand that it is a "will it start test". BUT will it perform correctly under load ???
As in...partially clogged jets...
I'm still a firm believer and long time customer, and recommend
"Sta-Bil 360 Marine" stabilizer with Regular gas (it is a different product than Sta-Bil storage) to all of my customers...put the correct amount in the can before filling the can at the gas station and use that mix all the time. I do see the result of people dumping stabilizer into the tank at the end of season...nasty mess.
My long term test...25 years...of Sta-Bil is a Kawasaki liquid cooled engine on a John Deere 345 tractor bought new. Sta-Bil used in it since new, tractor is subject to being used 12 months a year (there have been winters that it sat unstarted full of fuel for 6 months)...mowing, towing, snow blowing...original carb, bowl never off, no fuel issues. I work all the time on 1 year old engines that have carb issues.
I don't have Facebook so thanks👍
Awesome
Would be a neat experiment of the materials by putting a new carb kit and fuel line into 87 pump fuel with ethanol. Then either new old stock or strip an old engine made before ethanol for needle, seat, gaskets and fuel line into the same fuel. See when/how fast each one goes crunchy or falls apart.
You sure are right about that stuff being snake oil, always thought it, and you've confirmed it!
Great to see the ones with no additives start up after that long.
Taryl, those wouldn’t have started if they were mine! Your the small engine whisperer wizard!
Do another 3 months
I just moved south from Massachusetts to Florida three years ago. What I've found is the condensation filling the gas bowls and rusting the pin valves shut. Continually cleaning the carbs. Not to mention replacing fuel lines. All gummed up. Deterioration.
I know there’s people out here commenting less about the fuel additives and more about the Subaru engine durability.
I’m more interested of how well their pull start assemblies are. After all that pulling and only one small failure on one of the engines. Nice!
Agree about the snake oil. What do you think happen? Is the motor builders putting better fuel Lines and o rings or did the ethanol fuel change the formula?
AWESOME GUYS! Love your videos!
I only use non ethanol gasoline, from a reputable and high volume source, in my small engines. I never use any kind of stabilizer or treatment and have yet to have any kind of fuel related problems. My pressure washer that sat for over a year started up with only a few pulls.
My 89 winnebago sat 5 years and the carbureted 454 fired right up on 5 year old gas. Generator not so much.
Happy birthday sir
Great job on this series... Very very interesting results... I thought the one sitting outside, no effing way....
If anything, partial credit might have to go to the engines... they seem to run on anything.... That gas, 14 months old??? Can't be very good....
A lot of credit also goes to Taryl.... I seriously doubt half of your customers could just rip that rope, full out, 20 or so times......
So funny, when that outside one popped, I literally yelled at my screen, "You gotta be kidding me!!!" Heh heh heh! If it pops, it'll start eventually....
Taryl, a suggestion for you:
What about doing this test using an older engine too?
The Subaru's having to meet modern emissions (including fuel vapor evaporative emissions), no doubt have vent valves built into the fuel caps keeping the fuel tanks fairly well sealed, and preventing some fuel degradation.
What about doing this with an older engine that has a gas cap with the simple pinhole vents, or maybe something from the 90's, when they just started trying to do an automatic venting gas cap?
Must admit those Subaru engines are doing well on stale fuel...but I wonder what those new style Briggs and Scrapem engines with the plastic carbs and fuel jet would be like on this experiment if they were left as they always seem to be the common engine we find not starting or running properly on old fuel after winter in the UK. We don't seem to have issues with the engines like these with metal float bowls and carburettors much.
Happy birthday
Good old Lefty
I've used StarTron with great results, my push mower, which has been sitting since November fired up on the 2nd pull the other day.
Mine too except I mix metho in fuel !
I am so glad to see these results. I have bought some snake oil once years ago and never again. Never believed in the stuff. Your going to put them out of business haha.
I must admit I'm shocked that they started. We know that at some point all gasoline gets rancid and leaves resin in the carburetor and gas tank if it sits long enough and that ethanol is fuel does attract water. Phase separation is definitely a phenomenon that occurs. So what circumstances are preventing these issues in the engines being tested? Do newer engines have better sealing of the fuel system from air to prevent evaporation and contact with outside air due to EPA regulations? Have manufactures of newer engines started using rubber parts that are more resistant to ethanol than older engines due to the prevalence of ethanol fuels?
i didnt thjink the one out side would start and happy late birthday
I run straight pump gas in all my 4-cycle Equipment, never had a problem. Just let it run dry and empty the carb before storing it. In spring I fuel it up with fresh gas and all started and run good.
I never use fuel additives besides what ever they put in 2 stroke oil. Haven’t had any issues besides just the fuel being so old it didn’t want to run. Swapped the old mixed fuel that was 6 months old on the dot for fresh and all symptoms went away immediately. Fuel just didn’t have enough octane to run anymore. The symptoms it had was it was unable to rev up and felt like it had major carb issues to the point I was gonna take it to the dealer.
Octane??
@@chrisbcritter6112 yea its the rating of the fuel. when you go to the pump and buy gas its by the octane rating. the higher the number the more resistant the fuel is to detonating. if it drops to low nothing will really run on it. you can read up on the octane rating on wikipedia they explain it. in the states we use 2 different types and use the average of those for our rating
Be interesting to der ud additives has prevented water from forming in the carb bowls.
Snake oil. I have been using the same gas that is sealed and stored in a shed in the Spring that was leftover from the previous Fall every year for 20+ years in my Briggs and Lawnboy stuff. Never have run them out of fuel at the last use either.
I used to have a small yard and the gas container I had the first time I filled it up i filled it up full, i think it was a 2 or 3 gallon container. Basically this was my first yard, first mower. So the first year, i used hardly any of the gas, so i kept using the gas until it ran out, and I'm not kidding when i say i got 3 seasons out of the same gas. So when i hear people say that gas goes bad after a few months I just laugh because i personally know that's not the case. no additives, always sitting outside under my porch, 3 seasons using the same gas and the mower always fired up fine.
Wonder if carbs get plugged because of the extra dirt/contamination from actually using the mowers for a while. Everything you have was brand new. Might need a used engine/tank and a used fuel can let that sit around the gas will evaporate and you leave behind more dirt % in the fuel thats left.
one spritz of starter fluid and I think all the engines run on the first to third pull no matter how old the gas...i use Stabil but now I wonder...i guess if it doesn't hurt but I usually run everything dry at the end of the season...i would just put some stabil in the left over gas in the can
You need an octane test kit to see how the octane holds up.
Do you think there could be a difference between winter and summer blend fuels? Maybe one type "stays fresh" longer 🤷♂️🤷♂️
Does the relative age of the engine or motor factor at all? Those Subies were brand new. Would a worn out 15 plus year old Briggs powered mower still start treated with this stuff?
Personally i wouldn't waste my money on additives..just use a good quality non oxygenated ethanol free gasoline and keep the machine in a garage or shed
@@leeharris3061 I use any and all cheap fuel with ethanol. The way I avoid carb and fuel system issues is shutting all my equipment off with the fuel valve and burning all fuel out of the carb before storage. Been doing this for years and it's never failed me. Mostly I just have to jump start the first time.
If you have not put new fuel lines and a new carb rebuild kit you would have problems.
@@johnisley1285 not sure who your comment is directed to but after installing my fuel valve carb replacement is a thing of the past. Most of the carbs I replace now are on other people's equipment.
Not in the sense of being worn out, but in the sense of EPA compliance for fuel vapor emissions.
Without a doubt those one year old Subie's have to meet much stricter standards for fuel vapor control than what a 15 year old Briggs would have, meaning the fuel tanks are much tighter to air, which would mean less fuel evaporation, oxidization, and contamination that would cause the fuel to degrade faster.
if you can, try this great experiment with chainsaw engines.
lol whats the trike next to the outside engine .. got distracted
Wonder if hot temps would cause the gas to go bad.
Are we learning that fuel additives are "snake oil" or that Subaru makes some really bitchin' engines?!!
Let's give some kudos to Subaru. I know the co. exited the small engine market some time go but probably only because it is so competitive, not because their engines are inferior in any way. I want one! And I want a long crankshaft & light flywheel so I can put it on a mower.
June 1st it is
Do the Subaru engines leak oil
Idk is it common for em to
They don’t, but oil leaks are easy to fix on small engines
Holy crap! Ditch the snake oil! I appreciate all the hard work you guys are doing! I got a working lawnmower to tell you if you want it! Just pay for shipping!
I can't find the April one
Question,do you think an electronic ignition coil could go on the 143296032 8hp tecumseh with points and condenser
Hey Taryl, I live in the same climate as you. It has been my experince that when I leave my lawnmower sit over the winter, I have no problum starting in the spring. When I put my snowblower away I drain the fuel. I belive it has to do with the tempeture. the cold presurves the fuel, and the heat gums it up. That's just my 2 cents been doing it that way for 45 years. Thanks
Yep. Here in the Mojave desert, ethanol polluted gad goes bad in 8 to 10 weeks. Smells like paint thinner, looks like orange juice. I only use ethanol free for things that aren't used a lot.
Now that's interesting, Particularly in such low temperature.
i wonder did the winter temp slow down the rate of evaporation of the more volatile parts of the petroleum ?
I think it would be really interesting to get some input maybe from the makers of the engines and possibly even the sponsors who gave them to you hopefully they have watched the series they probably won’t but hay it’s worth a shot. I also wonder if Subaru would want the engines to further dissect them on the effects of all the different fuel additives you have used to see what type of changes they may need to make to improve their product. Hay just some thoughts who knows where it will lead but I’ve been watching this from the beginning and it’s very interesting to me.
hey you guys are great with lawnmowers, etc. however, that salesperson got you, where are the doors and the steering-wheel, the rest of the subaru-car? Mmmm...:) ha ha
I've found keeping gas in a can that is as full as possible and has very little air in it works best for preserving gas.
what was the last car you drove, or remember with a manual choke? 240Z
🍺🍺🍺🍺cheer !!!!'
thanks taryl ..... all my ride on mowers now i turn the fuel off and let the carby run dry when finished mowing ..... every time i start them they fire strait up
Can you test longer term like a snowblower used in February then not again until december?
Whewwwww !!!
you should try a engine with a100 hours on it maybe a little lower compression
Happy Birthday Taryl...didn't know it was your birthday...
