So by your logic that stations add 5% water to sell more gas. So in a typical 20,000 gallon tank at a gas station, the first 1,000 gallons out of the pump would be pure water. Doesn't seem like a way to sell more gas to me.
i think that is the problem, he likes to hear himself talk and has no clue

ok nevermind i cant explain this. but any ways cheap gas=bad the gas store owners get there gas from shady places that do shady stuff like add water to gas. i dont know the % but i know they do stuff like that because 10 cars in a week at a dealership for that prob and they said they filled up at the same place. so yeah. sorry i didnt know all the math stuff. im not a very bright person i just got out of high school...and skiped all my classes to go to the auto shop. i missed out on that stuff.

Are you beginning to learn now that you should have not tried to get around school so much and now paying for it.
Better to listen and learn that to talk like a dits.
Sure there are places that try to put it over on the public, thinking they will get lots of money out of the deal but they get caught because they are not to smart either.
You still have lots of time to learn.

There are a lot of things going on in the gas market and various places in the country that cause problems.
A station that just has a lot of condensation in their tanks is enough to bring customers a problem without really trying.
In a small tank, use only one bottle of Heet type additive and give it a chance to fully work.
Put too much in and you get a poor running motor besided the water, so go easy and give some time to clear. Excess alky makes the motor run lean and is detected by the OX sensors, fuel mileage goes down until it is all cleared out.
Been thru this more than once over the years.

Thank you Bluegrass, make more sense than anything I have searched about the topic: "Excess alky makes the motor run lean and is detected by the OX sensors, fuel mileage goes down until it is all cleared out."

I've seen it done, and you're spot on...it doesn't turn out too well since it doesn't "water-down" the fuel, instead it pumps nearly straight water.

We had a gas station owner here in Buffalo try to water down the fuel during our October '06 storm that knocked out a lot of the power in the area. He was one of the few in the area that still had power.

It didn't take the cops too long to figure out why there were all these broke down cars in the street right in front of his station.

O.K. there is some reason to believe that there is some water in the pumps at certain places. I know for a fact that Sheets gas (VA area etc.) has gotten numerous complaints about the fact that their diesels are having engine problems due too the water content in their gas. One of the ladies that owns the other barn in VA had too have her F350 Dually PSD (2005) completely overhauled because there was water in the diesel and she never had a problem until she noticed that sheets gas was cheaper so she started tanking there... a big mistake, as her PSD started too die thanks too their crap gas. I know that some truckers won't even tank up there but they do take advantage of their rest area lol.

Funny I noticed this thread

My friend (a mechanic) and I were just talking about this subject last night. He said he's talked to some guys that deliver the fuel to the big franchise stations and the mom and pop stations as well, and the guy told him that there is a certain amount of water (not much) that will sit at the bottom of the storage tanks at almost all stations, and that when they deliver new fuel to the stations, the pressure from pumping the gas into the storage tanks will stir or mix the water with the gas (temporarily) and that the water will settle back to the bottom, as others have already stated, WATER IS HEAVIER THAN GAS! You don't want to fill up while a tanker is replenishing a stations supply or a little while thereafter since there's probably a little water mixed in with the gas at that time. Btw, Texaco stations are the only one's with their own brand of gas and Sunoco, Shell, and Citgo being the better of all the others out there. So the only way the stations could make any money by your theory, is if they were to constantly be "stirring" their tanks Not to mention they would be out of business fast as I'm sure word would get out that those stations were trashing vehicles left and right I do agree with you on dropping the tank though, providing there's not too much gas in it and if it's not to hard to do. Better safe than sorry!
