What would be the best fuel additive or cleaner to make the fuel in my car be more stabilized and just better fuel for the engine and i run 89/91 just depending on prices, just looking at longevity of the engine

If you feel the need to..run tank to nearly empty, dump a whole can of seafoam in, fill up and be done with it.

None at all would be best...

It is a good idea to switch brands now and then, as they each use different additives. Also, if your engine runs OK on 87 octane (yuk) then there is no reason to ever buy 91...

That was just an idiot letting his vacuum line suck down an entire can of seafoam... My Mustang when I first got it had start up issues whenever it was hot (previously ran). I was running 87 at the time. I was near empty and put an entire can of seafoam in along with a tank of 91 and she barely has the trouble starting ever since. Used to do it at least once per day, it's been over a month and it hasn't happened yet.

Next time you fill up put a can of seafoam in right before you put the nozzle in. A funnel would help.

Ford makes it quite clear in the shop manual that NO oil or fuel additives are needed or recommended. The only exception to this food me would be a high mileage (100k+) engine that had been horribly neglected.

We (SWMBO and I) have for 40 years regularly run our cars to 250k or more miles--I have never used any fuel or oil additives--they are not needed if you keep the oil clean and use major brand fuel...

Neither my previous v6 nor my current v8 have had manuals in the car ( were owners cars tho ) but just the thought of ethanol and some gas around her would have some water in it, but a bp around here is opening a non ethanol pump and ill be going there for sure, thanks for the info guys

You can download the owner's manuals from Ford--click here.

Ethanol is hygroscopic, meaning that to a point (a 60/40 ethanol/water mix or so) it absorbs water into solution leaving no raw water in fuel tank. It is an ingredient in some brands of "Dry Gas", the additive used in colder climates to prevent water in the fuel tank/lines from freezing.

One could also argue that the water held in solution in the ethanol adds to engine performance by cooling combustion temperatures--same as does water injection...

name brand fuel. buddy reccomends newly opened gas stations, or popular ones (fuel gets used and replaced more frequently)

otherwise if you need to blow the carbon out, just burn rubber and haul a$$ for a bit. Road trips on the highway are supposed to help

EDIT
also, didnt meant to dig up an old thread. I forgot I was researching and not viewing whats new.
