Lounge mechanics: Drove 2 miles through rainstorm with gas cap off - what are the odds?

That's the worry now (there were bad portents way before leading up). I know nothing, so all I heard was that water in the gas would ruin the engine.

But leading up to this were all the following little incidents:

* ITEM: All I needed to do was to drop some lab results from the primary doctor to the cardiologist's office, asking the "nurse"? to give a note to the card, could he evaluate the results as to whether he thinks I need heart diagnostics. Not due for a regular cardio appointment for a year. (Leaving out details.) He's a super cardio so I thought his staff would be super, too. So this person, who might or might not be a nurse looked at the papers and I told her (above). She turned with (suspicion?) and said, "Did these lab come from your doctor?" Yes. "Did he *see* them?" I said, yes/of course. She said, "They're not SIGNED." I said that they came from a lab, went to my doctor, who presented the results, that we've been doing this for about 15 years, that he doesn't SIGN the lab results. She said that this cardiologist DOES. I asked whether she has worked for more than one doctor. She said she works for *five*!1 I said, but all HERE, not different doctors from outside this one practice? She said, all here. I said that my point is that different doctors from outside ONE practice have different habits. She said she was skeptical about that. Then we proceeded to go round and around about her saying she would get the doctor to see my request right away and my saying this is NOT an emergency, that I have the same symptoms that I had in August and for years past. She said she would still get the doctor to blah blah. Sheesh.

* ITEM: My dog eats a meal of one envelop type thing, plus a night snack of a handful of dry. The evelopes run out the most frequently, the dry lasts for months, so I'm used to buying the envelops. As I was leaving frustrated from the "nurse," the radio was alerting to an approaching rainstorm with possible large hail. It was dark but not raining yet. I also needed to fill up. I rushed into the store to the far end in a hurry and grabbed the dog food. The express lane was jammed, so I went to the far end to the self-check-out and started to rush out. It was now drizzling and getting harder. When I got inside the car I looked at the food and it was THE ENVELOPES (not the dry). It was starting to rain harder and I was stressed as to whether to let it go or go back inside for the dry, and decided to go inside. Went through the whole schmear. I had a sudden urgency to use the loo and went over there. It was closed for cleaning. Out front, the rain was now coming down hard and big thundering. I pulled into the gas pumps (that are roofed) and filled up. Finishing up, I rushed into the car and turned into the now pouring rain with possibility of hail. Got a couple of red lights and the side mirror showed the lid to the gas tank OPEN. Shit, I didn't know whether the CAP was also off or not. Got home, about 2 miles. Sure enough the cap was off.

So, what kind of karma is hounding me today?!1 And now home with the rain gone I went to check to see whether there is also an interior (to the gas lid/cap) quarter-sized little lid and there isn't. Started the ignition and it started.

So, no problem with water/gas?

Not that bad moisture gets in the gas all the time. Some automobiles used to inject water into the combustion chamber as a way to increase mileage

Not in only 2 miles. But I would go ahead and do the fuel treatment just to be sure. The major thing you do not want to happen is have your tank rust!

BTW: You can read up on water injection into engines: https://en.wikipedia.org/wiki/Water_injection_(engine)

It comes in a yellow bottle and is subtitled "gas line antifreeze and water remover." (There's also an "Iso-HEET" that comes in a red bottle. The Iso-HEET also cleans your fuel injectors. Pick your favorite color.) It is a "mutual solvent" - it dissolves in both gasoline and water - so it forces the two liquids to mix. Buy two bottles. Pour in the first one, then (and this is VERY important!) go to a big parking lot like a mall on Sunday morning. Accelerate to about 30 mph, then stomp on the brakes. Do that three times. That'll slosh around the gas and get the water mixed in good. Then go refuel your car. Drive around like you usually do until you're down to a quarter tank, then put in the second bottle the same way you put in the first one.

Of super unleaded through the car. The higher octane might help.

Have a water trap at the bottom of the gas tank, as the fuel pump and in tank filter is located on the top of the tank.
This helps keep moisture out of the fuel system, most cars get a bit of water in the bottom of the gas tank because of the natural moisture in the air which condenses and falls to the bottom due to daily temperature changes.

A can of Good gas treatment on a regular basis will usually do the trick. ( about every two months or so)
