Ethanol does not cause buildups of carbon on the valves, or varnish on the injectors. Most knowledgeable people will point out that today's fuel contains enough injector cleaner to keep the fuel system functioning fine.
Some engineers argue cut-rate gasoline retailers provide fuels with lower-quality additive packages that can build up deposits on fuel injectors and on intake valves. Others can build up deposits in combustion chambers and may lead to intake valve sticking. These engineers claim lower levels of additives can have negative impacts on engine performance and vehicle responsiveness.
If you agree with the statement, or like to reduce a possibility of deposit buildup, you can only fill up at Top Tier rated gasoline retailers. These include: 76, Phillips 66, Chevron, QuikTrip, Exxon, Texaco, MFA Oil Co. and Mobil.
If you are really meticulous, knowing that additive packages differ between Top Tier retailers, you can switch brands monthly so that each chemical package gets it's chance to remove what another may have left behind.
If you must add your own package, then buy Chevron - TECHRON Concentrate Fuel System Cleaner. But don't go overboard on the dosing. mmmkay?!!

This statement is the one ALL additive makers wish you didnt know about.

At the risk of starting one of THOSE discussions / rants, at the last oil change my dealership gave me a heads-up on recommended maintenance coming up in the next year: coolant flush and replacement, changing the automatic transmission fluid, and cleaning the fuel injectors.
I too use top tier gasoline, and after 40K miles there hasn't been a hint of injector fouling. (I know what that feels like from my old 300ZX/TT). I agree with my dealer's first two recommendations, but I'm skeptical of the third.
Trolling for revenue?

Coincidently, there is a Shell station 4 miles from my house across the border in MA that is the lowest price around so I'm not paying any penalty for a Top Tier gas. I have a Shell station 1 mile away here in RI that averages 16 cents more a gallon so as you would expect, I drive all my vehicles the extra 3 miles.

DUH!!! What does your manual say about all of those services? You'd think GM would know at least as much about these cars as a dealer service department. Yet GM continues to write these manuals without warning you that your deframis rods need to be removed and cleaned every 6 months.
However, GM says nothing about flushing your brake fluid ever, but most people with experience in brake work recommend a flush every couple of years. Especially if you will be using the brakes hard.
The GM manuals are a good starting point, but not quite enough for those who want to take the best possible care of their cars.

Two bottles of Techron (one bottle in each of two tankfuls) at the beginning of each Corvette season seems to work fine for me.
Not interested in paying 20 cents a gallon more for top tier gas (when I can find it).
I rotate branded premiums to keep the additives fighting.

Certainly, some shops will be trolling for business, or simply don't know what the proper services are.

Don't waste your time/money with a fuel injection service. I use Chevron in my cars most of the time because I get a discount for using their card and I pay off every payday. I also throw a bottle of Lucas cleaner in the tank every 6 months or so. Cheaper than techron (about 60%) and seems to work just as good.
The times I don't use Chevron is when it cost $.20-.30 a gallon more than the gas station across the street. $.10 more a gallon is fine but that is all that it is worth. Some "top tier" gas stations around here charge you $.14-.16 more per gallon just to increase from 85 (regular to 87 (mid grade) then the same jump from mid to premium. If a gas station doesn't advertise the price of their premium then I keep looking.

One should park outside the Marathon nurse tanks in Campaign County in Illinois and watch all the various branded fuel haulers drive in all day long, fill up and drive to their various stations in that distribution area.
Or in Davenport Ia. along the Mississippi where the tanks are filled by the barges from the gulf refineries. Any gas from your favorite brand came from the same source. Same thing with the pipelines all gas is pulled from them also.
Top tier my @ss.
