"It is advisable to run your gas tank down once in awhile because of the ethanol content.
It can separate from the gasoline if water from condensation etc exceeds some level."

Yes, and no. Ethanol is bad news any which way you slice it.

Fuel pickup is in the bottom of your tank so if there is any water it will get sucked up immediately. But if ethanol is present the water will be suspended in solution along with the ethanol until so much water accumulates the ethanol and water fall out to the bottom. If this happens your vehicle will not run. The remaining gasoline will still be cloudy with water and ethanol. Additives to "remedy" ethanol problems are very similar to ethanol. They "solve" the problem by increasing the ethanol-like properties so even more water can be carried before it falls out.

Tried. Haven't found anything that works.

Ford has a diesel additive that helped in my Powerstroke but seems to hurt MPG in my Bluetec.

It can separate from the gasoline if water from condensation etc exceeds some level. Alcohol
or ethanol is corrosive for seals and parts in general. Which is why it is so bad in lawn mowers etc now
that are stored over the winter.

Adding Techron or a similar fuel additive is good to keep injectors clean every few thousand miles.

There are two classes of aftermarket additives: 1) those that are primarily to prevent some sort of problem and, 2) those that are supposed to make the fuel more efficient in some way.

In the vast majority of cases, simply using a Top Tier brand of fuel is all that's really necessary.

OTOH, there are some worthy additions to the fuel that one can make. One of them is PRI-G for gas and PRI-D for diesel. I've been using this product for years with very good results. It brings fuel back up to new specs and is especially good for low mileage drivers and those who use generic gasoline. Another is Ethanol Defense. I've been testing this additive. It's supposed to eliminate the shortcomings of E10-E15 fuels. Initial results look promising but I haven't used it enough to recommend it.

I recently used one in my truck when the check engine light came on, but we still had to exchange an air valve in the injector system for it to stay off. The truck ran smoother after using the additive, but I am not a regular user of additives of any type.

Before ethanol was fused into our gas supplies, I had to use it eevry winter to absorb water in the fuel system as it would freeze the lines in sub zero weather. Now, just a little Chevron Techron once year to help keep the back of the valves clean and fuel stabilizer for lawn, boat, and trimmer gas over winter.

I've used Sea Foam for my lawn tractor after it began "surging". After 15 minutes the problem was resolved and hasn't returned. I also use another "fuel system cleaner" years ago on a 1994 Dodge B250 Ram Van after it began to hesitate on takeoff. The problem was also resolved. I only use Stabil-It for my small engines and always use non-ethanol Regular 87 Octane for all vehicles and equipment.

I run 4 ounces of Power Service diesel Kleen with each 14 gallon fill-up of D2 in my Jetta.

Not so much for injector cleaning but more for additional lubrication for the high pressure fuel pump since the switch to Ultra Low Sulphur diesel. It is the sulphur that provides lubrication.

Used various types recommended by manufacturer. Unknown performance variation, seems to be for cutting the carbon buildup in the carburetor.
Not even sure of that using additive every 4 tanks

I checked various sites for reviews on PRI-G, Houkster, and they come back very positive, without exception. It appears to have multiple virtues: compensation for ethanol, cleaner, storage stabilizer, emissions correction are mentioned prominently.

Particularly strong endorsements for boat and small-engine (yard & farm) owners, and people who have large storage tanks on their property.

Thanks for the heads-up!

If one uses a Top Tier fuel, any additives for things like fuel injector cleaning will be unnecessary.

I so use a product called PRI-G that keeps fuel fresh since I don't drive very much any more.

Have tried various types but none in the last 10 years or so, since they appear to do nothing and cost much more than gasoline. Have never had a fuel-related problem or had to have any injectors "cleaned". Regular gas will clean as well as anything - try it on a greasy part some time!
