NOTE: this test relies on the hygroscopic nature of alcohol, e.g. it's ability to absorb water. Because some water may already be present in ethanol/gasoline blended fuel, the measured result is approximate.

Scope
This method determines the amount, if any, of alcohol present in gasoline. This test is designed specifically for field-testing where time and simplicity are important factors.

Summary of Method
A sample of gasoline is shaken at room temperature with an amount of added water. The volume increase of water is proportional to the amount of alcohol initially in the fuel sample. Nine (9) parts of the gasoline sample are combined with one (1) part water.

because I'M used to replying to people that have a mentally of a 2year old ,you do not have the mental capacity to understand.
I know about the evaporator systems also the "o" rings in my Titan work just fine toluene, acetone and main component of gas benzene two of which are rubber solvents one is a solvent for "cleaning" up fiberglass residue.
Also the parts in the truck fuel system work just fine with ethanol in fact the conversion cpu runs e85% just fine.

GOGOGOODYEAR so what is your question?

Daurel, I just realized the confusion that could have been caused by my mistake of using ICE instead of Internal Combustion Engine. That would be a motor instead of ice; as in frozen water that wouldn't be really frozen when in mix with higher percentages of ethanol.

And they also use Beet juice on the roads for ice.

Daurel, have you checked the OEM part spec on your o-rings for injectors on that VK56DE flex fuel engine? No, didn't think so. The pigs must have gotten in your way to the junk yard. Let me give you a hint; 3. Most part replacement houses will handle one unit style; the one with the largest margin and covers most bases. So using your web search tool for AutoFarm won't tell you about the differences.

And in the past 30 years are you saying only one part on vapor recovery systems? No canisters, pumps, cap seals, vent relays or return lines? Then you obviously got lost in the chicken house! To stupid as they poop and eat in the same spot everyday too.

And who mandated the use of MTBE? Same people who are now saying ethanol is wonderful. They could have switched to ethanol 80 years ago, but didn't for some other reason.

So do you wear a helmet riding that bike? Neither does Gary Busey and he has turned out 'smarter' and handsome for all the spills he's had. Maybe you should try.

The point of water in the fuel isn't for freezing or rust. It's about paying money to burn water that mixes into the gas. Then burning it all the time. Back in the day dry-gas was mixed when needed, not everyday. But those gaskets and fittings just love the water they can grab onto. Then they break or become too porous to their job; preventing fuel leaks. But the fact is ethanol does carry water with it. It's good, and bad. But I would rather have the moonshine to drink.

Have a great day!

tdioiler What planet are you on? You seem to think this is the 40's it is not last I knew (for over 30years!) the fuel systems have been pretty much sealed the vapors from the gas directed into the air intake system of the automobile as goldsseeker has stated you don not have a clue. Steel gas tanks rusting YEA Right Like there are cars stranded all over the place from rusted gas tanks Maybe in Detroit where they pour salt and calcium on the roads most anyone can tell a Michigan car from the gaping rust holes in a new model car. I suppose you are going to tell me ethanol caused that also. on

borsht You need to check your facts FACT LOOK UP the PN on a Nissan Titan fuel pump model year 2005 OH DARN the PN for the FFV and the regular Titan are""" Guess what the same! FORD,GENERAL MOTORS & DOGE Fuel systems PN since 2001 are the same parts for FFV's and non FFV's.
ALSO the LAST BS claim gas stations HAD TO BY LAW remove ALL STEEL underground fuel tanks because DRUM ROLL RUST!!! Caused from condensation and poor maintenance This was going on LONG before Ethanol was ever heard of.

And LAST take out ethanol and add MTBE gives water an unpleasant taste at very low concentrations, and thus can render large quantities of groundwater non-potable. MTBE is often introduced into water-supply aquifers by leaking underground storage tanks (USTs) at gasoline stations or by gasoline containing MTBE spilled onto the ground. The higher water solubility and persistence of MTBE cause it to travel faster and farther than many other components of gasoline when released into an aquifer

NO THANK YOU!!!

This whole thread reminds me how darned old I am. Apparently, I'm one of the few who remembers frozen fuel lines. It was a common event 30 years ago. Since then two things have changed. Ethanol in the fuel and closed fuel systems, that minimize water vapor entering the fuel system.

Some people just do not have a clue. The more ethanol you have in your tank, the less likely you are to have more water as it remains in suspension and goes right out the tailpipe. With ethanol blends there it is not likely you would ever have gasline freezeup.

As you increase the percentages of ethanol, water problems are less likely. With pure ethanol, it would be impossible to have water problems.

" make sure you don't have a steel gas tank, it will rust." LOL!

Try telling that to the highway dept in many states as they spread tons of salt on the roads every winter. I can assure you that will rust your gas tanks and nearly everything else made of steel on your car.

Hello Daurel

If all the car parts are compatible with BOTH gasoline and ethanol things will be OK. As far as harm to your fuel system is concerned.
i.e make sure you don't have a steel gas tank, it will rust.
This is why all the gas stations have had to rid themselves of steel tanks.

IMHO this alcohol fad will go away. You get the worst of both fuels when you mix them.

Daurel, you are right; water and ICE doesn't mix. So they force us to use more ethanol (which absorbs water) and we have more water in our engines.

How much does that help your engine? Don't think so.

So we pay for water with our gas because it can be absorbed by the alcohol?
If you want to poor water in your tank have at it.
Do not think it will bode well with your car.

I'll keep my gas in my tank, even though I don't like ethanol. Too expensive to test

Screw it, cheaper to just drink it.
