I have an 08', 22,000 miles. Do you add any gas treatment occassionaly, meaning fuel injector cleaners, sulfur deposit cleaners, stuff like that? All I have done so far is premium and Chevron, BP gas as much as possible.

I use BG 44k every 20K or so. Even tho I use top tier, it makes me feel better

Just as a preventative measure, I run through a tank of gas treated with 1 bottle of Techron before I change the oil at the end of the season.

I do not use anything. I use 91 and I have not had any issues.

I buy Techron at Costco for $15 per six pack. It costs $6 a bottle at Walmart. I put a bottle in about every 3000 miles, usually before a long trip. Its very little money for the piece of mind.

Nope, I use 91 or 93 octane and that seems to be fine, no need in my opinion for any additives.

Keeps the fuel sending unit clean in the tank. Sure cheaper than replacing the fuel sending unit. Good price at Costco. I'll check that out!

BG 44K, without a doubt, is the king-daddy of fuel additives.

I do a seafoam treatment every ~15K miles or so. 1 can in the gas tank, 1/2 can in the crank case, and you can use the other 1/2 can through a vacuum line to clean out the top of the motor.

I do the same.

I've learned a lot from you folks here on the forum! My DD was running like poop...ping, clink in the engine on acceleration..and I ALWAYS run 93 octane from Hess or Gulf (sorry..no Chevrons up here). I ran a concentrated tank of TECHRON through the Hemi... now she purrs.

Think I'll put a can through the Vette as preventative maintainance...piece of mind thing.

I think I need to do this myself, Ive noticed that there seems to be a slight hesitation on acceleration. I have put in additives in the past, but its been awhile. 67,000 miles.. I may need to get new injectors.

At every oil change:

...made by Techron. The new fuels all have detergent additives in them to keep the injectors, valves, etc. clean so using an additive is just a waste of money. But, if you must and have money to burn, either a bottle of Techron Fuel System Concentrate Plus (not the Techron "Fuel Injector Cleaner" sold at Costco for cheap), GM Fuel System Treatment Plus (same product) or a can of Sea Foam are best to give you that warm fuzzy.

PS: the older C5s had the fuel sending unit problem that was corrected on the later models and subsequently the C6s.

yep, I use something recommended by a well known Tribologist in tune to 1oz per 10gal in every tank.

The only difference between this and Techron Fuel System Cleaner is price. A 20oz. bottle of Techron is $10, and the same GM bottle is $26 (at a dealer). The GM bottle even has the Chevron logo and patent # molded into the bottom of the bottle.

GOLD72

Generally yes. I tried AMSOIL PI at 30k miles and saw a 1 to 1-1/2 mpg increase in fuel economy within a couple of thousand miles. Seems to meet the claims that AMSOIL makes for it. Techron never made that kind of difference for me previously.

Chevron used to sell at their gas stations a bottle black in color with gold print and it was for the engine deposits and other stuff. It wasn't the same as the fuel injector Chevron cleaner and cost alot more for one bottle of this stuff?
Is this still around?

LS WON

Same here.
