Oil & Fuel Stabil in gas mix

[TWD]

Dutch445- I found Seafoam at Walmart in the auto section where Heet and other additives is.

SeaFoam user here too. :thumbsup:

I've used it to get cars running that have been sitting for 3 years, and running the same fuel in their tank as when parked :confused2:

Also works great in a vac line or throttle body too. There are some YouTube videos on this, and how to do it but the instructions on the bottle work. It has smoothed the idle in more than one of my vehicles over the years.

I normally only treat the engine through the TB / Intake once a year, and use it for Generator gas storage or anything that will have gas in it for longer than 3 months.

when i use seafoam in my highmilage bmw i put 1/4 can in the gas 1/4 can in the oil and pull the vaccum line off the powerbrake cylinder and pull the last 1/2 can in thru the intake. run it for 5-10 miles bring it home and change the oil. if you run it thru the intake you may wanna do your 10 miles on back roads. it will make em smoke like a SOB :laughing:

here in MD the 10% ethanol is in all taxed onroad gas. ive been cutting 93octane with 110octane unleaded VP race gas(60/40) since they istituted the ethanol ruling here.

on the avaition gas i dont know about in a 4stroke but i was running it in 250r quadracer and it was plugging the powervalve up moreso than the 110 race gas was.

I have been bit by keeping Stabil too long as mentioned by several other posters. It plugged my pressure washer and when I pulled the carb apart there were hard crystals in it. I ran my old bottle of Stabil through a coffee filter and it had crstalized so I chucked it.

I buy a new bottle every year now.

I have a 1963 Ford 2000 tractor with a gas engine that I use once every 6 to 8 weeks and when I do use it I put anywhere from 2 to 4 hours on it. In between the times I use it I leave the tank full of gas and the gas has had Stabil added. Up until yesterday I have had no trouble starting it and it always runs just fine. Yesterday it would not start, checked and I had spark so I took the gas line off the card and gas was coming from the tank just fine and it also smelled like good gas. I took the carb off and lifted the top off to look into the float bowl area and there was no gas, the float was hanging down but the needle valve was up in the shutoff position. I very gently touched the needle valve with a screwdriver and it dropped down. So I took off the float and looked into the seat area where the needle seat is and all looked well and clean. Blew it out and put it together and it runs as usual. As easy as the needle valve dropped down I am assuming I could have probably tapped on the side of the carb without removing it and it may have dropped down and it would have filled the bowl with gas and would have started.
I am thinking about using more Stabil in my gas mix since I am assuming maybe the gas was beginning to deteriorate? What do you think. Will also start to add fuel injector/carb cleaner in my mix, is this a good idea?

Thanks for the help- Oldstuff

I don't see what you hope to gain by adding more Stabil than the label calls for. Deteriorated gas didn't cause your problem.
