Beer in the gas tank
Some local little bastards dumped beer in my gas tank tonight and then proceded to throw the bottle at the windshield. Luckily the windshield did not break. I am just curious what beer will do to the gas and my engine. I just filled it up earlier today, which sucks.

i would drain the tank, beer is mostly water, and your engine likes gasoline not water. A tank of gas and the time to drain the tank is a lot less than a new engine. oh and get a locking gas cap
they are only about 10 bucks.

I woulden't drain the whole thing, water is heaver than gas, and water is polar and oil baced products are not (or do I have that backward?) so they will not mix, so the water should have setteled to the bottem of the tank, also allitle water won't hurt anything, it will accually clean the combuston chambers, and in proper proportians it will increase power because, when water turns to steam it expands 41,000 times it's origanal volume, and it also cools the combustion chamber, (WWII fighters used it the way we use nitrous, warter injection is more expensive to set up, and you don't quite get the same type of power from it, but it dosen't beat the engine as much and you can advance the timing insted of retarding it like you do with nitrous) the problem is that in a gas tank it is unregulated, your fuel pickup could all of a sudden get a sudden burst of water, and it will displace the fuel and stall your engine. Just my $0.02

Go ahead and try, it won't hurt anything to put it in, I don't think it will hurt anything to run it like it is now, by the way, to waste beer hear is a carnel sin and anybody caught doing it would get their @$$ kicked, so there was somthing wrong whith whoever did it anyways, also how do you know they put it in the tank?

there was a puddle and drip[ lines down the quarter panel. The cap was not screwed on tight and there was a puddle under the cap that smelled like alcohol. The beer bottle was in front of the car all smashed. It was a Miller High Life 24 oz. The local machanic said to use dry gas and to not let the tank get down low before I fill it nexted.

Yeah, put a little drygas or alcohol in there. The water will mix with it and be burned in the combustion chamber.

well I did pee in it earlier that day, heard it would give me 20HP. Anywhoozle, the alarm went off, the kids ran off. The cops did find who did it. Now they get to pay for the chip in my windshield, which they probably won't pay for but it would be nice. I've been driving it throughout the day with no problems.
If it was a TPI engine, i'd say to just be paranoid and safe, drain the tank. But your engine is a TBI, and the water will have to travel all through the intake before it gets to the cylinder, which pretty much garantees it's going to evaporate.
