Ethanol gums up engines - this is why typical gasoline since the 2000s will brick your lawnmower - need to take apart carburetor and clean to get working again.
Using ethanol free gas (usually available at Sheets, Wawa, etc) is best for vehicles, lawnmowers, and everything else. Better MPG as well because gasoline is more energy dense than ethanol.
Ethanol is the reason engines need these cleaners in the first place.
Ethanol is to engines what high fructose corn syrup is to the human body; they both come from corn, heavily subsidized by our tax dollars.

But, you may need evaporator cleaner as cheap try to fix the code.
If it will not address the issue then look for O2 sensors, likely to be replaced. You need to check for both before and after O2 sensors via OBD2 to see which one isn't good.
And the worst case CAT converter replacement.
If above are unknown for you then talk to trusted mechanic.

for the CRV (got it in 2012 brand new) I usually use BP or Mobile.
the 2004 got it last march at 95k. don't really seem to have any fuel injector issue. it has other problem I've fixed but not fuel system
Your fuel SHOULD NEVER BE MIXED WITH ENGINE OIL. Fuel dilution of engine oil will ruin it's lubrication properties. Do a quick google search for 'fuel dilution in oil'.
Water does NOT MIX readily with fuel, they have different densities.
You're also in CA, you've got a lot of urban myths in your post. I don't know if it's CA specific rumors, but most of them are false. ie. ARCO doesn't mix water in the fuel to acheive lower prices, etc.
If you're in Southern CA, fuel comes from two refineries, regardless of brand. The tankers just get additive packages (Techron, VPower, etc) on the way out of the refinery and it gets mixed in the tank on the way to the station.
Fuel deposits can wind up in engine oil as part of combusion. The oil literally catches continaminants and keeps them from building up in the engine casing.
Not urban myths, sorry!

Let's say for example, you always fuel at Chevron, that gas already has Techron in it, would you change your oil after 4 tanks of gas? (I'm guessing at the actual amount each gallon should contain at the pump). No, of course not, that would be ridiculous.
If you need to change your oil after using a bottle of fuel cleaner (any type), then your engine has more serious issues that need to be addressed.
I can't find a single news article of shady tanker truck drivers regularly stealing fuel by adding water, so I won't comment on it. Plenty of articles on leaky tanks letting water in, general condensation. Maybe you have a link to a local article, that would be an interesting read.
"This is a HUGE problem in emerging markets; but in fact theft of gasoline and other high value liquid fuels happens even in developed markets such as the US and Europe."
I believe them after having my tank tested. We couldn't figure it out. Until we drained my tank and found water.
We were amazed my injectors survived. And it happened right after fueling from tank empty at a gas station on the CA/AZ border.
Breaking Bad didn't come up with the idea. Computers count fuel in and out. You get a spare tank, stop the truck along the way. Swap the $5/gallon gas, then add water to replace it.
As to changing oil... my point was the BEST time to do FI injector to clean the fuel system is right before an oil change, so that if deposits are knocked lose into the oil, that doesn't ride with you for another 7,500 miles needlessly.
Is it something to dwell on? No. But it is a best practice.
BTW you can get a lot of acetone for 25 bux.
3.5oz/10 Gals works
Chevron recently severely nerfed the regular non-HM variant from having 45-50% PEA to just 10-20%. PEA is the ingredient that does the actual cleaning. The high milage version has 20-25% PEA.
Look at the composition info for the following documents from Chevron. Specifically, "01154100-5179P". That is labeled as trade secret but it's pretty clear it's PEA since other brands' fuel system cleaner use the same string in their documentation.
