Which gas stabilizer do yall use

Used to use Stabil but for the last 6 years have been using Evinrude Johnson fuel stabilizer, works very well.
 
Well, I use Renegade HR 93. My buddy sells race fuel so I buy a few 5 gallon cans when he orders. The HR 93 is intended for motor sports and boats. Ethanol free fuel isn't sold in CT. I know it's overkill, but it's worth it to me in the long run not having any fuel issues. My Suzuki 20 & Suzuki 6 4 strokes don't use much gas. I burn less than 10 gallons a duck season. If ethanol free gas was sold at the pump here, I would definitely use that.

My buddy uses pump gas with Seafoam in the Duck Water boat we use for divers and sea ducks.

In a feel good followup, I dropped off the boat with a gummed up motor yesterday. I'm picking it up in 15 minutes, all ready to go. Apparently, fuel treated with Seafoam doesn't stay good for three years or more. Who knew? Dumbass. :oops: I'm really lucky that the mechanic, an old friend going back to childhood, has a shop with a couple of employees across the street from my office.

I'm the outlier here. Never used non ethanol but have used a few stabilizers in my boat and mower , chainsaws and other lawn maint. tools thru the years. Found quickly Red Stabil didn,t cu. t it When they introduced blue stabil several years ago I started using that and have never had a fuel issue in anything on high test pump gas. I always mix it at storage rate and on lawn tools, chain saws & power washer in particular, it may go 8 months between uses. Many years ago when non ethanol was first introduced I did have a couple fuel related issues on boat motor and 4 wheeler. Was using a product sold by Mercury motors back then (probably 25 years ago at least). It sucked. Made the switch to seafoam then but latter went to blue stabil and use that in everything except the 90 which gets Quick Silver Stage 1 in it. I,ve been probably 24 years without a fuel issue in anything and only the newer 25 has a water separator on it. If on boat motors I find myself with gas thats over 6 months old i,ll simply pump it into trk. to be on safe side . Really that only occasionally happen s with 90 tank where its large. Maybe i,m lucky but system has worked flawlessly for myself once I discovered the right stabilizers.

I, too, only use blue Stabil as recommended by a very good friend of mine (hunting and fishing partner for about 40 years) and he is also a small engine and airplane mechanic. Have been using it for about 20 years. Never have had a problem since using it for ALL my small engines.
 
Duck boat, just drain it and start fresh every year. Pump the gas out of the 9 gallon tank and put it in mower. I have one of those battery powered gas pumps from harbor freight and it works really well. New stuff goes in when I do my yearly fall maintenance, prime and go.

Bass boat, I use mercury stuff made specifically for mercury. They make stabilizer but also make 2 other concoctions that I run when filling up to help keep injectors clean etc. Probably why I still have a 18 year old 2 stroke going strong still. I kind of cant wait til it goes pop though. Want to get rid of the oil tank and make more room in the back hatch and cant wait to go to a 200 hp 4 stroke on the bass boat. Just cant justify costs when this one is still running so good.
 
Even using Stabil 360 Marine (blue), you do need to still rotate your gas out.

My duck boat goes into commission around October of each year. In February, I'll usually siphon what's left in the tank into one of my vehicles. Then I'll go grab a quick gallon of premium, add in some blue Stabil, and run the motor on that to change the oil and finish my maintenance. That way when the boat goes back into commission in October, again, there's only 7 months on the gas. That gets topped off with fresh premium with blue Stabil, and we start over again. My rig is stored in the garage so the gas is a little more stable than if it was sitting outside in the cold, hot sun, rain, etc.

The gas now is horrible. I recently helped a neighbor get a snowblower going with less than a year old gas. He never added stabilizer and paid the price. Of course this was during a snowstorm.

Pro-tip for snowblowers and other carbed equipment: At the end of the season, siphon the old fuel out, run it dry AND then pull the drain plug on the carb bowl and let the couple ounces of gas in there run out. This is the one that people don't know about and forget to do. Once that gas goes bad and phase-separates in the bowl, bad stuff happens. I've done this with my old 15hp 2-stroke Johnson as well.

My wife pokes fun at me saying that I am always siphoning gas in and out of something. After watching me help fix my neighbors snowblower in a snowstorm in 25 degree weather, she now understands.
 
I use stabil and non ethanol gas. I pull the big duck boat out of the barn in the spring and start and run it for 5 minutes. then I pull it out and do the same thing in early Sept. this boat doesn't typically get used for hunting until late October or early November. My mud motor boat has a copperhead on it with a 23hp Briggs so it just uses regular gas (non alcohol) I add some stabil to it and start and run it a couple of times in the off season. I do the same thing with the other 2 stroke equipment, snow blowers, log splitter, ect. the diesel equipment gets diesel stabilizer added and again, I start and run them every 3 or 4 months. the chain saws, I run canned fuel in them for storage at the end of the season. my own mix for during the season.
never any gummed up carburetors so far, knock on wood
 
big boat has a built-in tank and doesn't come out of the lake until after the season is over. Because it is in the lake full time it gets ethanol free from the marina. I just put Stabil in at the end of the season then run the motor through it's "winterize" process once it is sitting on the trailer but still in the lake. The question I have never found an answer to is the "leave a full tank or an low tank" for storage. Seems to get the Ford vs Chevy answer.... For the last 10 years plus, I just do whatever is in the tank and don't worry about it. No fuel issues so far. For small yard tools, I just run them dry before putting them away.
 
Marine stabile in everything except my truck. 1oz per 5 gallons of gas (regular 87 octane that has ethanol).

I did have an idling issue with my 1987 15hp evinrude this fall, Seafoam Pro seemed to have been what the Dr. ordered for that issue.
 
I religiously use non-ethanol and seafoam in all of my boat motors (a 90 & 8hp 2 cycle) and lawn equipment. Seems to work and haven’t had issues with fuel sitting during the off season.
