I finally used my Mr Funnel water separating funnel today for the first time. I filled up my brand new jerry can with non ethanol 90 octane gas and transported it home where it sat in my shed for about a week to 10 days. Today I used this new gas can in conjunction with the funnel to fill my lawn mower. When I finished I saw that there was a bit of sediment and water in the bottom of the funnel's sump. Is it common for gas to have water and sediment in it like this? Also, this station I used has a fairly high turnover since it offers non ethanol and there was not a tanker actively pumping the tanks while I was filling up. What do you guys think?

Photo of what I'm talking about:

 
This is common...at least in my area. I use one of those funnels on all the fuel for my OPE and generators. Almost never fail to find some sort of contamination. What I see most often looks like little flakes of rust.
 
Fuel will hold some water in solution. The amount it'll hold varies by temperature. When the weather cools in the Fall is when we see more accumulation of water in the bottom of the tanks--it drops out of solution or suspension or whatever is happening.
 
Another reason I use dry gas every few thousand miles even though people tell me not to.

I am not convinced that my 5-6k mile usage of chevron techron concentrate plus takes care of all the water in the tank.

The gas station I worked at as a kid, the owner (mechanic) used to use the stuff religiously in his 1990's model caprice police package sedan. He obviously only used gas from his own station, so I followed suit. In the winter, I usually add a small bottle of dry gas at every fill up.

My mechanic now, of the last 15 years, also is a big proponent of gas treatments for fuel injector cleaning, removal of water from the system, and general fuel system care.

Gasoline and water never form a "solution." There may be some emulsification, depending on the level of surfactant (detergent) in the fuel.

What do you think of the millions of us that never use a fuel system additive and never have a fuel system problem.

"dry gas" is a small bottle, one-shot deal typically sold in gas stations, etc. mostly for use in carb'ed engines during winter time to fight fuel line and carb freezing due to moisture(water) in gas.

IMHO methyl hydrate in gas to absorb moisture no longer needed in pressurised FI gasoline systems.

It's methyl hydrate if I recall.

There are some gas stations here in NY that have been fined for running their pumps with no filters. Many multiple times in the same year. This goes on quite often. Think how often weights and measures comes by to certify the pumps, I worked at a gas station in high school, 6 days a week and 7 over the summers for two years. I NEVER saw an inspector.

That said,

I also don't know many people that keep cars as long as I do.

For most I know, they are disposable, and 95% of my friends lease their vehicles.

After my experience owning a 2002 Audi A6 4.2 turbo, I can understand why they are leased! I will never BUY another german vehicle, I will most certainly lease one.

Your thinking is outdated by about 15 years. Explain to us what a small bottle of methanol can do, that 10% ethanol in gasoline cannot do when it comes to taking care of water in the tank.
 
Just run your tank down, fill up, repeat. The water settles out anyway and the fuel pickup is at the bottom of the tank so it's going to pick up the water anyway.

And before you jump on me thinking it will ruin your fuel pump. Nope - been doing it in many cars and all with well over 100k not a fuel pump replaced. The fuel pump sits in a sump of gasoline and even then it is cooled more by the fuel going over it than being bathed in the stuff.
