Fuel additives?

I was wondering, since the LFX is DI, those fuel additives with detergents and such would do absolutely nothing for the direct injection since the fuel itself does not come in contact with exterior of the valves (intake or exhaust), but would a good injector cleaner (Valvoline, Techron) still work? Just wondering before I go out and waste my $$! Thanks.

If it is LFX and E85 compatible, that stuff will clean out the fuel system better than any snake oil, just fill up once every couple of months with E85 and you will be good to go.

So that ethanol is pretty potent stuff, eh? Cool, hadn't thought about that!

LFX/LLT are NOT E85 acceptable. And it still wouldn't clean anything above the cylinder walls, i.e., valves/intake, etc.

The only thing that can be introduced would not go into the gas. It has to go in the airstream ahead of the valves. A product like Seafoam, introduced through the brake vacuum line would work.

I knew this was coming. No offense, but I have yet to hear an "opinion" on LFX E85 compatability that I am comfortable with. Many here say yes -many say no. Some Chevy dealerships say yes - some say no. Some mechanics say yes - some say no.

Worst of all... I have tried to get an "official statement" from GM/Chevy off the web and haven't been able to. I've looked on sites that list E85 vehicle, such as:
http://propelfuels.com/vehicles and
http://ncsc.ncsu.edu/wp-content/uploads/E85-Flex-Fuel-Vehicle-List-3_12.pdf
Camaro LFX/LLT not listed. One of the "rules of thumb" seems to be if the gas cap is yellow, it will accept E85. My EFX V6 Camaro's cap is Black. My 2010 Dodge Ram 1500 however, has a yellow cap and an E85 badge on the tailgate.
Sorry to sidetrack but I have to say (for me anyway, as it stands right now) no E85 is going to come near my filler tube.

Techron is far from snake oil.

The injectors and fuel pump will benefit from techron, but yes the overall benefits are less with DI. techron was formulated specifically to alleviate deposits on the backside of intakes valves.
