Techron
On an earlier thread, I asked about problems gas gauges had with accuracy on how much gas is in the tank and what the gauge shows. I saw the post on how to take out the sender unit and clean it. Other people said to use Techron. Is this the Techron http://www.walmart.com/search/search...h_constraint=0
Also, some said that they used 2 bottles and the gas gauge started to work correctly again. Do they mean use 2 bottles at one time or follow the directions and use every 3,000 miles. Thanks, Ed

They mean use 2 bottles at the same time. I've known people that swear they've cleared up fuel gauge inaccuracies using 2 bottles to "clean" the sender--I've personnally never had any luck myself. As someone else said you'll likely end up replacing the sending unit, which isn't a bad job it's done from the top and you don't remove the gas tank.

C5 owners that have had issues with wrong gas gauge readings usually get resolution by adding a couple bottles of Techron. But the sending unit is different compared to the C4 tank unit.
The sending unit is relatively easy to replace, but adding two bottles of Techron when you fill the tank is certainly worth a try. Techron is easy to find.

From everything I've read, high sulfur content in fuels is what causes problems with the sending unit contacts. Sometimes there will be a rash of failures and the oil companys (most notably Shell) will foot the bill for new ones. Do a GOOGLE for "bad gasoline" for more info or to see if there is anything in your area.
As to Techron or any other miracles - like nitrogen - most fuels (particularly in this Town), come from a single distribution point and supposedly, additives are added when the truck is filled up. I've yet to see the delivery guy on top of the Chevron truck pouring in a bottle or two of Techron. The makeup of gasoline, in CA, is strictly regulated and according to the Regulators, has all of the detergents it needs when it leaves the refinery. Wherever you live, you might see if there's similar. Start with www."yourstate".gov

Only thing I have used is Seafoam or Stabil for storage purposes. Usually, I would drive the car so it isn't really necessary. Some Gas Dry in the winter is about it. No snake oils will go in my vehicles, period. I don't use additives in my diesel either except for anti-gel.

Okay, I just bought 2 bottles of Techron, however, there were 2 different sizes. The smaller one was for gas tanks up to 12 gallons and the larger ones were for tanks up to 20 gallons. I'm supposed to put 2 bottles in but do I put in the small or large bottles?

I have had the same experience...twice. Save your money, if it is that bad, take it apart and clean it.
SunCr is correct.
My friend worked for a oil company and use to tell me about all the different brand trucks that would pull up to the same spout to fill up.

The sulfur issue is common in GM's and not under heard of in other brands, best way to avoid is find some Top Tier gasoline in your area and only buy there. Do a search online for Top Tier gas and you will find a website that gives locations near you. Shell, Chevron are known examples to me. BP, Sunoco, Exxon, are usually better gas than others. I used to run Sunoco all the time, then the station closed...??? Now I run BP.
Besides, a bottle of it is WAY cheaper than a new sending unit.
I can testify that is does work, my fuel gauge was inaccurate I used one bottle and all was well. I use at least one a year in all my vehicles.

Assuming it works and assuming that proper cleaning won't fix it, yes. I would think that if you take it out and clean it and it doesn't work, no amount of "cleaner in a can" will make it work. In a C4, it isn't too difficult to get to the tank so why not? While you are there, in an older car, you can also change the sock which can get nasty and maybe even find out if there is debris in the tank.
