I personally use (2) things: #1). Sta-bil 360 Marine Formula (my mechanic says: boats sit the most and the marine version of the 360 is the best supposedly). Despite the directions I use 1oz per gallons... #2). SeaFoam "with the Sta-bil" at a ratio of 2oz to each gallon. I have been doing this for nearly 2 decades without any carburetor issues.
I drain the fuel on whatever I know it’s gonna be sitting and then I put non-ethanol fuel and run my equipment whatever it may be for a little while so the non-ethanol fuel is in the carburetors and then I shut it down and put it away. I found this to be the best way to winterize.
I have had problems with stabil left in over winter. NO problems at all with seafoam. I am a seafoam fan. Well worth it at my off the grid cabin.
Thanks for comment Jack !!!!
Great subject Steve! I'll be interested in your results. For the time being, I'm sticking with adding original Sta-Bil starting in the fall in my Zero Turn and using Seafoam for cleaning parts. Everything else I have is 2 stroke and according to the Stihl fuel additive I use. No additional protection is needed. Been working for me great for years.
Rick I put the 360 in my gensets at the camp so I'm looking for a good startup in May like usual , I put it in the lawn tractor too and left it with a full tank in October.
I've had very good luck using Seafoam over the years. I run the engines 'dry' then put the fuel with additives. Start the engine, let run a short while and when later I need it, it starts. I should add, I live around 5000 fees elevation with sub zero winters and hot summers in very dry high dessert.
Thanks good video
Hi Jo
I buy the seafoam by the gallon and so far I've never had a gummed up carb. Cheers 👍
I found some marine stuff at CTC that is supposed to help with regular gas instead of premium problems. Two year old gas is working fine. Thank you for your thoughts, Steve. Stay safe and stay warm
There are so many additives out there so I guess the only way to tell if their any good is to try them . Take Care Sean
My 2 cents been using Sta-Bil from the start of the E10 being sold in everything from my outdoor equipment to my muscle cars and never had a fuel related problem. I will admit if by some chance the gas don't get used after a season like a snowblower it gets siphoned out and new added. I even took the carb and bowl off a 30+ mower just to check and no corrosion at all was found. I also use it year round and just consider it cheap insurance.
👍
Love your honesty Steve! I only use pre-mixed, stabilized fuel in my weedeater and have had no issues. Luckily we can still get non-ethanol gas around here.
Thanks Jay , l just leave the chemical engineering to the other youtube trained experts on chemical composition and use and stick to just being honest LOL
Great video. I am like you Steve, been using Sea Foam for years. Just for curiosity's sake, I took apart the carburetor on my Cub Cadet GT 2550 with a Kohler Command 22 HP V twin engine. I purchased this garden tractor new in 2007. Store it every winter without draining the carburetor. Sense new, been using Sea Foam using 2 ounces per gallon. I do fill the fuel tank completely full when storing it for winter and add a bit more Sea Foam in the tank and run the machine for about 8 or so min. before shutting the engine off for storage. This past summer when taking off the carburetor for inspection, it looked like new inside. Clean as a whistle. I must say, I was very impressed. After 15 years and stored every winter, the carburetor looked like new inside. And that is using 10% ethanol regular fuel. Sense Bozo Biden is pushing for more ethanol to be used in fuel here in the states, and living in Michigan, which does not require the percentage of ethanol to be labeled on the pump, I have switched to non-ethanol fuel. It is a bit pricey, but I don't want to run into costly problems down the road due to ethanol over 10 % in pump gas. So, my conclusion is, Sea Foam works very well for seasonal storage. But I would not trust any fuel stabilizer for more than that amount of time without running the engine to remove the old fuel within the float bowl. Noting worse than having to take off a carburetor for cleaning when the times comes to use the machine. And, I have done my share of doing that throughout the years. But not much sense using Sea Foam in every small engine fuel container. As you, speaking from experience, Sea Foam is an excellent fuel additive. Works very well for seasonal storage if used 2 ounces per gallon or more if you are so inclined. Like Sea Foam proclaims, you can't overuse the stuff. Loved your video, and your personal experience using Sea Foam. As long as it is still available, I will continue to use it in all my outdoor power equipment.
Hi Russell
My 7000w generac generator at my northern camp since 2006 has been running off regular gas with ethanol but I use seafoam 1oz per gallon all the time as in all my 4 stroke engines . I took the fuel bowl off a couple of years ago , spotless 👍 It does seem all the other stabilizers work too but the seafoam on sale is the lowest cost so far. I have repaired so many engines from old gas left in them so I know the fuel stabilizers are required these days. Cheers 👍
The only persons advice I would trust without issue on the channel "Project Farm". I know nothing about additives
I don't trust anyone on youtube :) when it comes to chemical engineering because anyone can make a video saying anything without any real knowledge but they sure can sell a lot of products LOL I have never watched that channel so I cant say . Cheers Bud
@@SteveRobReviews I have watched project farm, very interesting & good information, on the STA-BIL storage I used it for the first time last year & it worked out fine, didn't hurt my engine & no problems starting it up this season, just bought some STA-BIL 360 to try out on my mower, I only use non ethanol gas, but I use additives for extra protection.
Seafoam has been around forever and is great and Sta-Bil is good stuff too. I have tried a stabilizer from Lucas and it has done good for me here. You made several good points on the products.
Lloyd its just trying one and if it works well stick with it because throughout the world we have different gasoline so use what works best in your area . Cheers
You gave the best advice I've ever heard. Great work man and thanks
Thanks Michael much appreciated 👍
Good review Steve I have no idea about any of them! I guess I need to start using at least one of them! I trust your advice!
Annie in reality if your not having any problems with your machinery as is maybe your gust as well to keep doing as you are . There are so many variables that go into using a stabilizer but it seem you just may not need any.
I go for si foam ....I have had great result with it but I think the most important thing is what kind of gaz you buy.....more import for me than the stabilizer....CHEERS
Yes I agree as I try to buy the super grade of fuel but the additive is like an insurance policy hoping you never need to use it LOL Cheers Buddy.
@@SteveRobReviews I do the same....CHEERS
I've been running 360 in my sxs since I bought it brand new any time I'm going to park it for a while. I haven't had any issues with it but you will notice the exhaust smells like BBQ lighter fluid burning. I've also used it for my storage cans. I never have gas sitting long.
When I was snowmobiling I liked the star tron ethanol treatment. We get that crap ethanol gas here and in my old carb sleds it made a huge improvement in performance.
I like Seafoam too. It’s triple the price as compared to Sta Bil 360. I used red Sta bil last summer no issues. I went out and started my equipment when it got to 35-40 here in Minnesota. Even with synthetic 10W-30 I had to keep chocking on and off till they stayed running. I had to use Sta bil starting fluid to get my Honda going. I’m going to use the amber 360 this summer.
How's she goin'? It sure is a smart move to add these products to your gas. I have been doing this since forever and I'm a Sta-bil guy. Probably because it was cheaper than the Seafoam and also because I liked the container it came in. Easy to meter out the correct amount to add to your fuel!!! LOL Great video Steve, and I agree 100%, I have no idea what's in these products but I know they work!!! Take care!!
Mike if something works stick with it but so many youtube experts love to get people to switch to their favorite stuff with a link to buy of course :) Cheers bud.
Been using Stabil in all my can stored gas for the last 20 years and it has always kept my small engines running great. They started carrying ethanol free gas near me so I switched but still use stabil
The best stabilizer is the one you have success with . 👍
Thanks, that was very helpful, but one question for the "STA-BIL Storage Fuel Stabilizer." If I use 1oz for every 2-1/2 gallons of gas for one or two years for storage in my lawn mower, can I use that same gas with the fuel stabilizer in it to cut my grass the following year or would I have to dump all that gas and stabilizer out and use straight gasoline the following year?
It best to not go past the 2 year storage time as most only use it to last over the winter of non use.
@@SteveRobReviews In other words can I use my lawn equipment with the gas and fuel stabilizer mixture?
@@Thomas-nz4uh Absolutely
Good morning Steve 👍 Great and Very important subject especially for generator users in ( standby ) mode for emergency power failure like myself that the fuel is inside the fuel reservoir for long period 👍 and also corrosion prevention inside it too 👍😊 My generator has running very well since more 10 yrs but i did use various fuel stabiliser from Canadian Tire or UPA NAPA and I also put for my two stroke engines oil mixe gas canister too 👍 Great informative video Steve and Happy Lubricated St Valentine's day ( real good joke man on my video that you left their yesterday !!! ) 🤣🤣🤣👍😊 Cheers !!!
If the products you bought do the job well stick with them. My gensets sit from nov to may without starting and so far they start every season no problem and that's all we want eh :) Cheers
@@SteveRobReviews 😊👍
I use the seafoam to clean carburator or injectors. I use sta-bil for storage of fuel. Good results so far, about yrs
Good plan 👍
I do the same!
Always an interesting topic. Kind of like when you ask people what brand of oil filter is best. As usual you took the pragmatic view, Steve. I’ve used both products myself. Like you said, stick to these two brands and judge for yourself. 👍
Colin I'm no youtube expert on anything :) just like to share what I use and what works for me . Cheers bud.
Gotta tell ya, I just LUV this guy! Why he doesn’t have over 50K or more Subscribers, well, there isn’t much accounting for “taste” these days!
Hey Steve! I got into a debate with a Family member over Thanksgiving, and I was looking up stuff and came across this video, so late comment. Excellent stuff. Like I’ve said before, I appreciate your practical and common sense approach to things.
From my limited knowledge, here is the breakdown as I have learned:
(1). Yes, you are right and Seafoam is the more expensive alternative. And people in general are not as familiar with it, as they are StaBil. Two local shops near me, both Authorized Stihl dealers, advise me to use Seafoam, even over StaBil! This is coming from the Technicians btw. I have used SeaFoam in the past, but didn’t realize it stabilized the fuels for up to two years!
(2). The Red StaBil ‘Storage was designed more for storage of like older cars, antiques, etc. and prevents the build up of moisture that will rust out tanks. Probably the better option for long term storage.
(3). StaBil 360 is designed more for regular, intermittent use, and is also designed to fight the effects of Ethanol in fuels. One would use it in a, let’s say, portable Generator, with a full tank.
I had my local dealer fix my portable Generac ‘Genny,’ and they said to keep the tank full, or as full as possible, and use SaeFoam, and just start it up on a regular basis. This leads into my opening statement a Family member said, about how I should drain it out, and let it run dry, to which I said, but what about the gas in a can? We all know, or should know, gas can deteriorate in a can as well. Based upon what qualified technicians tell me, I use NON E 91/93 octane gas, in all my small engine equipment, both 4 stroke and 2 stroke. I have StaBil 360 in the Genny now, but will probably switch to SeaFoam, as I went a little long between start ups this last time, due to being an ‘idiot!’ It did not want to start, and was surging for the first few minutes, but settled down and ran alright the rest of the 15 minutes. I hook up an old Skil Circ saw, and start and stop it to maintain the Field Coil, and it puts a little load on the Genny. Speaking of long, that’s what this comment has become, so I will shut up now. Hope this helps somebody out there?! Stay safe and healthy! Cheers! 👍✌🇨🇦 🇺🇸 😊
George I find the quality of parts in a carb and how old it is dictate running it dry or storing it with fuel in the carb. Older stuff i run dry as they were never designed for ethanol fuels and the newer stuff non wingwang cheap carbs I store with fuel in the carb with fuel stabilizer.
I quit using Stabil when I found it settle into the float bowl in a kind of white powder form and I see it started to plug the jets, not good. I switched to Seafoam after that and never looked back. It keeps my carbs clean and stabilizes fuel so I can use the gas in my tanks the next season. Some may have good luck with Stabil, but I won't be using it. Seafoam is better in my book.
Steve do you run the additive in your gas year long or just when you store your equipment during there off season?
I use a lot of fuel and fill 5 gallon containers so I do put the additive in at the same time but I don't store any gas over the winter except for the snowblower . Take Care Jack
Seems like the 360 is worth a try given how much it will stabilize versus how much you use. That being said, if something has worked for 20 years, why change it? So it’s a preference for sure. I will go with the value pricing. Thanks Steve!
Doug when I worked at my friends part store I got the seafoam for cost now the 1 gallon of seafoam is $100 so I will use up what I have and then onto the more concentrated option and se how I make out . Take Care .
I feel more balanced now Steve. Honestly, you speak truth.
Balanced is a good thing 👌 Cheers bobber .
if you use ethanol free fuel, do you really need these additives? i've always used ethanol free fuel in my lawn equipment and snowblower.. i've never had a carburetor gum up on me and not start the following season..on occasion i will add a little Seafoam but regardless i've never had any problems whether i use it or don't
Hi Vince
Depending on your location ethanol free fuel is not always available and in some places its over 20% . I never used stabilizer years back and never had a problem but today every spring I see machines that will not start because of gummed up carbs from the fuel. Interesting enough in my experience most have no idea about fuels and never read the owners manuals:)
I might add, I usually try and run the Genny, and any other equipment, every two - three weeks, and as the gas goes down, I top it off with “fresh” NON- E gas. It has worked so far. I keep the gas in the Genny, as I don’t want to be out under my back porch, in freezing weather, during an outage either in an ice storm (which we get a lot) or snow, and filling up a 7 gallon tank, and then trying to get a “dry” carb to start!
Cheers!
Hi George
That's a great way of knowing it's going to start👍
@@SteveRobReviews Thanks for the replies Steve!!! 👍👊😃
Scotty Kilmer who is a automotive mechanic for over 50 years says that using seafoam in newer Vehicles as a no no with all the new electronics and emissions. he is very knowledgeable, I would look him up and watch his video.
most of these stabilizers are going to be good for your lawn mower, small equipment etc. make sure if you have a two-stroke you use additives that are compatible with two-stroke engines.
Scotty fixed cars in his driveway in Texas 50 years ago . He's a good diyer at best but he hasn't worked on a car in decades . He is great at making youtube videos but not one real tech would refer to Scotty as a real tech , he's a youtube certified mechanic at best :) I would ask seafoam directly for any concerns you have as Scotty is not a reliable source of info unless your talking vehicles from 50 years ago . LOL
Scotty is no "mechanic" he's a babbling drunk.
Lol, Scotty is totally clueless.
I wonder if that sea foam would work for a pressure washer? Mine has been sitting on for over a year with gas in it and I tried to crank it today with no luck.
I had a 8hp snowblower I was working on the same , old gas left in , no start. I drained out all the fuel and poured in straight seafoam and let sit , a couple of days does well . Drained out the seafoam sitting in the float bowl and put gas in and it ran great . Worth a try if your not up to taking the carb off and cleaning it.
I only put stabilizer in fuel I'm going to store for 3 or 4 months or more. I put some in equipment when the season is over. I haven't had any problems except for dirt that I could have avoided if I would have strained my fuel like my Dad said to do. If you are going to use your fuel in a relatively short period of time do you suggest using stabilizer anyway?
I agree , buying and using fresh fuel is ideal and as you do used for off season storage.
Sta-bil has a video saying the red is for long term storage, the 360 is to be used as a fuel treatment, not for long term storage.
K100 is an emulsifier, mixes with water very, very well, but how does it work as a fuel stabalizer for winter storage?
Google knows. I don't :)
Good information to know bud. I've never used it I usually drain the gas out of every piece of equipment that I'm not using over certain seasons
Thanks James , we have such high swings in temps between seasons its a fight with fuel left in machines over the winter with condensation.
our snow blower and lawn mower need this. After theyre put away ... the next time they arent running so well. our snow blower has been running crappy for past 2 years...
Bud it makes a huge difference , sure try it out and see.
I use sta bill for years with no problem. But taryl fixes all had a year test with different ones and well ill say that its interesting to see. Im very intrested in your outcome.
Yes I'm looking forward to the results too. Some don't use anything and do well but every part of the world does not all share the same quality of fuel so thats a huge variable.
Steve, I've been pretty confused by everything I've seen on this subject on RUclips, but your comments strike me as very reasonable. When I used Sea Foam for fuel stabilization over the winter in my motorcycle and small equipment, I had no problems. But this year, I'm experimenting with the standard STA-BIL since it's somewhat more economical. I use a fuel stabilizer for winter storage in conjunction with fresh fuel and the fuel tank topped off to minimize moisture. One of the challenges here in Connecticut is the lack of ethanol-free gasoline at the pump. Do either of the above two products protect against the moisture absorbing properties of ethanol in gasoline? I don't know, but sure would like to use a product that does that.
Hi Geoff
I've tried all the three shown in the video extensively and in my experience all three worked great for me as I store all my engines from October till May so I pick the least expensive route for me but for those storing long term 1-2 years I'd go with the stabil products. I bought the stabil 360 on sale and it's priced lower than seafoam so that's what I'm using. Hope this helps 👍
Some hardware stores sell ethanol free gas in cans, like tru fuel at Lowes. There's no way of removing the hydrophilic properties of ethanol with any product. All you can do is add more anhydrous isopropanol or methanol to emulsify the water into the fuel.
Sea foam claims to not just stabilize the fuel but they claim i it cleans and lubricants deposits in your engine injectors ext. I watched a video from a very popular mechanic as well as yourself take ten different engines and use ten different stabilizers used 87 octane fuel then let them sit for 19 months in different weather conditions. After that he tried starting the engines and only two started stabil and VP fuel treatment then they dropped the bowl every single one had sludge with the exception of VP it had a crystal clear bowl. Most people are not going to let it sit for 19 months but that’s what I watched. I my self don’t like running them dry I use ethanol free gas with VP and some SeaFoam at the end of the year since you never know how long it’s going to be until i use my snowblower I run it dry put 4 cyl VP or tru fuel 8 oz run it through the carb for a few minutes and leave until next time. Thanks for your video your right that’s only what I do ..
each to there own as you said thumbs up shared i agree both good products if used proper
Yes sir were free to use what we want . Cheers
Have you seen the experiment that Taryl Fixes All's channel is running on this stuff? It's fascinating and the results have been bizarre thus far. It's been well over a year now that he's been doing it and the engine that has the non treated ethanol fuel still starts and runs like a champ, just as well as the engines with all the various fuel treatments. They appear to have a relatively Canadian type winter too.
Yes I watch all his vids. The only thing that is not universal is fuel quality as fuel in Alaska is not the same as Florida or Canada but overall in my experience the cold has less affect on fuel than the heat plus most big brand name winter blend fuels have additives and what I see is summer blends left over a season seen to degrade . The hot cold temp swings play havoc with condensation on 1/2 filled fuel tanks too. Cheers Chris
I'm not going to say there name but I will describe the bottle, lol. Good info Steve.
HAHAHA thanks buddy.
Fact check sta-bil is better for long term storage,,
Sta-bil 360 is better for short term storage.
But I do like the idea of using the empty bottle of sta-bil to use to measure out the amount of seafoam,which I use also use
In my usage the longest term I store my fuels is about 7 months so all three work great . I pick the one that is on sale for the lowest mixture of cost per gallon.
@@SteveRobReviews yes I do pick the sta-bil that's on sale.
I've purchased sta-bil 360 32 oz. for $16.99 @ my local tractor supply.
Thks for your reply from a subscribe in Pittsburgh Pa.

I run stabilized fuel in my boat engine always and im backwards in that my boating happens in winter. Duck hunting season
👍
I'm a huge believer in stabilizer fuel for my small engines! The smaller the engine, the more important it is IMO....but what do I know, I'm not an expert!! 😂 Seafoam liked your video...they ran their commercial at the conclusion of it 😋
I've never seen a seafoam comercial on RUclips yet 😅 There's a boatload of RUclips experts out there on chemical engineering HAHAHA. Take Care Dave
This is another reason why outdoor operated machinery is going battery. This is why gasoline will never come down in price , at lot of battery operated machinery is taking the place of gasoline . Gas powered equipment is not plug & play, battery is. As batteries are made over the years they have become better and giving you more running time and quicker charging time. Bad fuel is 90% of problems in a gasoline motor. These additives give you a window of time to use them and store them. Over the last 4 years I've replaced my blowers, chainsaws, push mowers, weed wackers, hedge trimmers, etc to battery . I buy the same make since I can use the same batteries on all of them. Laugh now about battery but it's coming soon, just look at your hand held power tools, they were a joke 15 years ago, not so much now. Even the contractors are using them. Battery is here to stay and will be in more demand year by year. Less pollution, less noise, less aggravation.
I use STA-BIL360 we are under a snow storm warning here in west Tenn 8 to 14 inches are expected and 2 more storms later this week I can,t handle this come on spring.
Wow that weather is not comming up from Florida, got a good idea from where 😅 Join the club buddy LOL
Good laughs abound. You said you can use Sta-Bil 360 a full 360 days a year...Doesn't a year have 365 days?
Glad to see someone is paying attention :)
fuel stabalizer vs emulsifier, could you comment on this? Have you ever used G100?
Never tried G100. I'm strictly a consumer not trained in providing a expert opionion. Cheers
They have it in the diesel fuel sta bil brand to.
👍
Ok so the sta-bil 360 or ethanol shield so can you put it on a fresh gas that's on a gas can to keep it fresh for spring time in also can you use it on a 2cyce
Hi Efren
Yes 4 stroke or 2 stroke . 👍

Used Stabil in leaf blower always started after winter for 7 years . Coil died so may buy a new Stihl ,old was Green machine
I do have a gas leafblower, but I won't buy another after buying this one. ruclips.net/video/KTOIRcpAVlI/видео.html
Shelf life of Sta-Bil is 2 years. What's the shelf life of Sea Foam?
From what I've read from the company as long as it has not turned cloudy its OK. I've had a container that was opened five years ago and still no cloudy condition.
Do an update to this video. Like to hear your opinion.
The stabil 360 is concentrated so if I can buy it for $7 a bottle it's the lowest cost but overall they all work great so it comes down to cost .
@@SteveRobReviews and before Sta bil expires run it in the vehicles to use it up.
I used the normal Sta-bil on the new genset. We'll have a look in a few more months to see but about a month ago it started fine.
Hi Brandon , starting it up every so often is a good thing to do as well. Cheers
I know exactly what you mean about that other product turning into a jelly, in the carb in my case. I just run them dry if they have a shut off and siphon out the gas and run them dry if they do not. Between the ATV, riding mower, pressure washer, lawn mower and snowblower the gas is rarely in the container more than three months and in my opinion does not degrade enough to put an additive in.
That's a great way to store your machinery Pat 👍
Always use non-oxy, 98 percent of your problems will be solved!!!
Problem is people using a great stabilizer with corn juice crap ethanol,,, if use pure gas those chemicals almost keep your gas for three years etc, not that I would leave it that long but through accident I learned.
👍
I like sea foam.
It's always worked for me too 👍
im running 2 yr old diesel in my brand new kioti ck2610 and 2 yr old gas in my toro zero turn with seafoam..no issues...i put about 1 to 2 ounces per gallon or more in every 1 gallon..literally sat 2 years and just being used...
I've never seen sea foam for sale here! I've no idea if it's good or bad? 🙈😂😂
Really thats interesting , ya might have to drive to London to get some . 😅😅
@@SteveRobReviews I think I’ll pass lol 😂
It’s available in every decent hardware store
@@abeneufeld9690 in what country?
thk u
You're welcome!
Not sure about seafoam, but stabil in the bottle is only good for two years.
I'd say that's about right 👍
I use seafoam in gas and diesel.... I get 2 years... I use the unused fuel 2 years later on vehicles and home boiler and diesel cars... I won't go past two years.
I can tell ya it's probably unnecessary in dry climates like Western Colorado. It's probably snake oil. But it's not too expensive so it's doable. I use about 50 gallons of portable canned gas and diesel a year.
The only way to check this product is to get 6 containers of gas from 3 different sources and do a lab test on all before and after. Let it sit 24 months on a shady shop shelf. Test again. And then run them in identical machines to see how it does. Who is going to do that? Much easier to just believe their snake oil is legit! 😆
The diesel anti-gel may do more. But again, not needed in Western Colorado. Dry climates have those benefits. But I use it anyways.
I have my doubts that any low mixture ratio of any chemical do anything for fuel. Likely all snake oil.
When I use fuel system cleaners I fill up with premium and put 1 bottle per gallon of 3 to 4 different fuel system cleaners. Once every 2 to 3 years. I still can't tell a difference at that strong concentration. It has made no noticeable difference in any of my cars and I've had 35ish of them and drive them until the wheels fall off or the motors fall out.
I drain and run the line fuel dry out of my chainsaws and lawn mowers every Winter. No issues ever. I also use cloth filtered and settled used motor oil and run that through my bar/chain and for anything that uses 2-cycle fuel. No issues. I also dump 2.5 gallon of it in every fill up of 35 gallons of diesel in my all-stock Dodge Cummins. Yes I change the fuel filter more often. That's the only cost. Takes 5 minutes to do that. Cost me $8 every 2 years for a filter.
I run a quart used motor oil per full gas tank in my cars also. It seems to keep things going good. Lubes the pump a little. Has no negative signs of smell or visual. Probably increases compression a little also.
Whatever works is what people will use even if there is no proof it actually works 😉
