What do you guys use for fuel additives? I have been using Lubro Moly Jectron, and Lubro Moly Valve Clean. I alternate the two at every fill up. I notice a 1.3 to 1.9 mpg improvement when I am faithfully using them, in which a missed treated tank is few and far between. Amsoil has some cleaners....any others out there that are inferior to others? Oh, I also fuel up at Shell and use super. Any comments much appreciated!

Haven't heard of it. Where do you get it? Never mind, found it online. With all the fuel additives, why this one?

Did you check the Fuel Additives forum we have here on BITOG? The question about best additives has been raised quite a few times there. But as is the case with everything, what's best depends on whom you ask. 
Personally, I did try both Jectron and also Techron Concentrate, but haven't really noticed any difference with either one.
Also, using it at every fillup is excessive, I think. UOAs have shown that even a single application contaminates oil, so using it very frequently may potentially have negative side effects, not for your fuel system, but possibly for your engine.

^I have heard that too. Yeah, I need to chill, but I can't help but want my vehicles to perform at their best. I'll check out the fuel additive section too. Thanks for the input!!
An occasional maintenance dose of Redline SI-1 fuel system cleaner, and just plain old watching where I buy my gas. I like Shell, just a preference with no data to back it up, but more than anything just a station with fairly new tanks/pumps and moves their inventory quickly.
marvel mystery oil and seafoam are my favorites
I have decided to stop treating my fuel and instead keep hooking up my car yearly to a complete fuel system machine.

Maybe. True detergency levels are up, but probably not at optimal levels to clean or keep things clean. Also, lots of additives contain a beneficial UCL (upper cylinder lube).
I personally use DSFM (*) in every vehicle at each fill-up. I get better numbers (mileage and UOA) by using the "fill-up" treatment vs. a more aggressive one. RedLine SI-1 would be a good exception in this case though, IMHO.
* Dyson Secret Fuel Mix. Propreitary formula that can be found on the Dyson Website. You have to join in order to access info there. NOT a plug, just advising where the info can be found.

How about CRC GTP, which is a Ester-based fuel system cleaner? I also like Berryman's B12 Chemtool, essentially straight Toluene, for my Audi allroad 2.7T.
Mods:
Can we move this to the 'fuel additives' section ?

Just stick with what your already using. You are seeing a mileage increase so why fix what isn't broken.

Actually, B12 is essentially mixed xylenes, butoxyehtanol, and propanol -- mostly xyxlenes. Toluene is a carbon short of being a xylene. Otherwise, similar though.

to: GMorg, i have a Q. do the things you listed in Berrymans B12 have no lube quality? if i remember xylene is a paint thinner, am i remembering right?
In response to morris, all of the main components in B12 are solvents. n-Propanol is rubbing alcohol without water (isopropanol). Mixed xylenes are benzene rings with two additional carbons at random, mutually exclusive locations. Butoxyethanol is a little more exotic. It is a butyl ether of ethylene glycol. It is the least volatile of the main constituents. I don't really see any lubricants in the mix. B12 is clearly a can of solvents.
thanks GMorg you guys are great. you are such a big help. thanks.

Ethanol added to the gas is a supreme "cleaner" to the point that it reduces lubricity as well as attracts moisture. That combination is about as bad as it gets for the internal combustion engine. Adding in reduced fuel economy is just a plus for forcing us into electric Go karts.
These new fuels are about as clean as clean gets. If they get much cleaner there won't be an internal combustion engine except in a museum.
I think it's best to add an UPC to the gas. If they'd just go full blown pure alcohol or something else like natural gas it would help so those of us that still drive real cars from the 60's or 70's could adapt since any engine can be adapted to whatever fuel they decide on.
