New Shell Gas with 20% More Cleaning Agents

You are lucky. The only Non Ethanol gas around here is over 200 miles away. I thought it was illegal here in NY. Apparently there is a loophole for some use. Here Shell is around $0.10 per gallon more than non top tier gas and around $0.15 per gallon more than no name, fly by night gas.

As others have pointed out, we also have catalytic converters. When hydrocarbons are burned, and burned more completely, there will be water. As for the old days, I used to see plenty of vehicles rust out their exhaust systems. Water was the culprit.

Fuel has changed. We have to accept that. Lead is gone for good. Ethanol is here for the foreseeable future. High detergent gas isn't a fad, either.

You are kidding, right?
Water can NOT evaporate from the fuel system.
A. Water sinks to the bottom of the gas tank, it can't evaporate from the bottom of the tank.
B. The fuel systems on modern vehicles are completely sealed making evaporation of ANYTHING from the fuel system impossible. If the fuel system looses it's seal it will throw a CEL.
C. Any water introduced into the fuel tank will continue to build-up in the bottom of the fuel tank over time until it reaches the level of the fuel pickup, then the engine will stop. The exception to this rule is when alcohol is mixed with gas. Alcohol attracts and absorbs water. Over time it can pick up whatever moisture is in a fuel tank and send it through to the engine to be burned.

This is why technically today with E10, small amounts of water in the tank or fuel should not cause issues.

Perhaps I should have said, eventually leave the system? Wrong use of terms, w/e. I specifically mentioned TRACE AMOUNT of water, as in not enough to actually settle out completely unless you let this tank of gas sit for longer than a few weeks in time. Even then, some tanks probably have 'some' moisture depending on age and older equipment. Even then, it's probably more like an unstable gas condition rather than 'water in the gas'.

...and yes, E10 with it's alcohol content will obviously make it a carrier for said moisture or 'trace amount' of water.

Now, we come full circle. Enough actual water to reach pickup tube or completely leave a growing pool of water in the system from initial said introduction of such as not just a trace amount, and it will definitely leave you stranded.
