Techron plus is the good stuff. All fuels leave some sort of build up on injectors and intake valves, some worse than others. When a fuel injected vehicle came into my service bay and was having drive ability issues I would recommend a fuel system cleaning. Using solvents that had techron in them would yield a better result than other cleaners at full strength.
BUT we use premium fuels that have cleaners in then already, most of them anyways. Vehicles that use premium fuels show less and most times no signs of build up in the intake system during repairs like intake gasket replacement. There is no way to know if yours is clean without looking inside, so adding an additive that is known to work is cheap insurance.
If there are 10 different brands of cleaners on the shelf, the 1.99 brand would take a lot more bottles to work as opposed to the $10 bottle.

All I use is Chevron Premium with, according to Chevron has Techron
in it. I pay their top $ price for it and my gauge still goes to empty every few months. Why should I pay for more Techron if its already in the gas?
I don't think Techron is that good or my gauge wouldn't give me trouble since it already has Techron in the gas, it should be keeping the sending unit clean already.
When ever the gauge stops working, I put Seafoam in and it fixes it right up.

Seafoam and I'm sure there are others that also work just as well if not better.
That's kinda what I thought. I bought a six pac of pro-gard from Costco and thought
maybe it might be the same. I've had my '99 since new and have never had any fuel sender problems yet ! Do you think that the sulfur content of fuel in different regions of the country might be a factor in how often the problem happens ? Just a thought.
Also I see where you can order a six pac of the Techron fuel system cleaner (20 oz.)
from Walmart for around $60,sure beats $13 a bottle from parts houses.
Yes, I think sulfur content is a factor.
Truth is, most fuel additives are more or less made up of the same compounds. The trade secret might vary, but it's the same "family" of compounds usually. Just take a look at the contents label next time you're at the store. I can't say ALL of them are the same, but from the major ones I've compared in the store, it was basically the same stuff. Furthermore, I've used several different brands, and they all fixed the gas gauge problem after being added. Now I usually just buy the one that's on sale (and there's ALWAYS a sale) when the gauge goes to E.
That's my opinion/experience on the matter. If you don't agree then by all means, keep using techron or seafoam or etc. I don't really care since it's not my car or money.
