How can you tell if you might have bad gas? I`m kind of suspect with the gas still remaining in my 250 Gal. farm tank, last filled 9 months ago. I did add StayBill but not quite the ratio suggested....Is its there any good way to know if its still OK? Thanks for your response/suggestions---Paul

I don't know about the gas in Ohio, but on a tour in central California, we stopped for gas. Soon after, the car started to run rough and stopped. I drained the sediment bulb and it ran OK for a while. Several cars which got gas at that same station had problems, but those who got gas at the station across the road, did not.

If water gets into the gas, it will settle to the bottom of the tank and usually if you drain the sediment bulb it will drain out the water. I have been told that the gas which contains ethanol will separate and water will form. I haven't had a problem with my cars which I drive around town.

So, if the gas in your tank separates, or if water seeps into the tank, you will have trouble.

Paul,

Did you get bulk delivery ?

How old is your tank ?

It could be water in your tank that was existing or water in the fuel delivery or condensation forming since then or water somehow leaking in ...

You can try & draw a sample to be tested by whoever delivers your fuel.....

There is a paste that you can smear on the end of your measuring stick that changes color if you have water in your gas. We used it all the time at the filling station. We would get it from our fuel supplier and test our tanks once a month. You may want to check with your supplier sometimes they will test it for you.

I don't know when the change begins, but really old gas smells awful. Not like gas at all.

I wouldn't worry about 9 month old gas. You can tell it's getting bad when it begins to smell like varnish.

How can you tell if you have bad gas? Well, you get really bad stomach pains and then no one wants to be near you.


(Someone had to say it!!!)

Bad gas will also cause your intake valves to stick in the open position. The voice of experience!! Texas T Party 2016.

This new gas seems like it's only good for 3_5 months and your carbs gummed up and it stinks. I have started draining my bowls or running the gas out of the carb until the engine dies off. Gas is terrible now if your store it very long. Tim

Ask your fuel supplier, see what they have to say about it.

https://shop.b3cfuel.com/ Found this "mechanic in a bottle test swab kit" Ordered it for $3.49 It tests for water and gas "quality" Anxious to give it a try when it arrives....nice solution if its reliable. Thanks for the above responses--Paul

That stuffs getting up there in age Paul. Not sure what you can do with it if it's already giving you trouble. Forget the stabil. It doesn't help a bit.

I've never used Stabil but my friend said he put it in his bobcat welder. We went to go weld something the other day after it had sat for a few months. Then after we took the carburetor apart and put it back, it started. An electric needle valve that shuts off the gas was stuck closed. I never can afford enough gas at once to worry about it.

I have not tried it in my T but wonder how well it would run with aviation 100 low lead.
It doesn't go bad like auto gas.

Here's a visual of what's going on with the gas. Water on bottom and gas is cloudy. Car has been sitting a few months.

You could probably pump out the water in the tank but that color looks like he**. Old fuel.

One of the issues with ethynol in the gas is that it is OK for closed systems like your modern car that uses fuel injectors from a sealed tank and goes through it in a few weeks.
In carb systems where it is exposed to air after the engine shuts off, it turns to glue. That is why most landscapers, outboard motor operaters and owners of WWII jeeps, use ethynol free gas. I use it in my jeep and in my T.

In addition to a possible water problem, if your bulk tank has a lot of air or the lid has been left off or it is vented in some way, the air exposure may be causing some problems as well.
