Water in the Tank?

[Bannon7414]

What are some of the symptoms of having water in you gas tank? My car pretty much sat for 2 months this winter with 1/4 tank and now she chokes when she starts and stalls out at times, could water in the tank be the reason? If so, what can i do to fix it? Its a 94 5.7L Caprice

Pour some DRY GAS or something like that in the tank, (not octane booster but dry gas) then fill the tank the rest of the way up w/ premium. you should probly try to siphon off the gunk that is in the tank if u can.

HEET Fuel Additive, a couple bottles.

Additives are ok but the best way is to drop the tank and completely drain it and take it to a radiator shop and have them flush it out real well and make sure it's bone dry before you put it back in then fill it up with just regular gas and let it run for a while to use up the little gas that was left in the lines.

I'm a college student so dropping the tank is too much right now. How many bottles of Iso-Heet should i use?

None. Find a station that sells ethanol blended fuel (most of them do now) and fill with E-10. If you have a place that sells E-85, pump a couple gallons of that in first, then fill with gasoline.

FWIW, "premium" gasoline may not work as well as lower octane fuel. Lower octane fuels are more volatile, and can burn better in the presence of water. "Premium" already has additives that slow the burning rate of the fuel. It is slightly less volatile.

Iso-Heet is isopropyl alcohol - yes, rubbing alcohol. Plain, old formula HEET is straight methanol. It is very corrosive to some fuel system components. Don't spill any on your finish, either. Most of that costs about $1.50 per 8-12 oz. bottle, or $15-18 per gallon. E-85 is about $2.20/gallon, and "regular" E-10 is about $3/gallon. Which is more effective?

[GreyGoose006]

you cant get E-85 where i live in Va, or E-10 for that matter

[Bannon7414]

Yea, I've never even heard of E-10 or E-anything else

well the E-# means that the gas is # percent ethanol. ethanol comes from corn, and, if you listen to the media, is supposedly going to help solve our high gas prices, cut global warming, and make the world a better place. the problem w/ E-85 is that it may cause problems on cars that were not designed for it. ethanol has a lower ammount of energy per quantity of fuel, so you need more of it to get the same power. that is why these new "FlexFuel" cars are so good to add turbos and such too, because the injectors can inject much more fuel than standard injectors, so all you need to do is remap the computer and VOILA- POWER!!!!
