Fuel Mileage Increase using additives by clongwell

I would hope people realize the clever marketing behind all of those outrageous claims of increased fuel mileage from these fuel additives.
 
The last two links were two products that claim alot. Both sites spend as much time trying to get you to sell their product than use it. Come on people...putting a giant pill in your gas tank. Are you kidding me! The last one is talking about CNBC World Business Review with Alexander Haig. It is well known that production costs for WBR are paid for by the company that wants there product on air. Please save your money.
 
You want to save gas...drive down the freeway at 55mph and don't show off your trucks power at every intersection.
 
Smoke and Mirrors...Smoke and Mirrors.

Please do not post phone numbers or any other contact information... this is against the rules, and opens you up for abuse as well.

You want to post that question in the Chevy Silverado: Problems & Solutions discussion for better response.

I have a 2005 2500HD with the duramax. I have 11000 miles on the engine. I recently pulled a 3000lb equipment trailer 440 miles and my mileage dropped to 9 mpg. The local dealer told me it could be the fuel filter. I need some help!

Did you look at your air filter gauge. Try a different fuel station.

Hey clongwell,
 
At 55mph, you do conserve fuel. However, I think every person on this board laughed when they read your recommendation to drive that slow to save fuel. Conservation is one thing. Actually extending or increasing your MPG is even better!
 
I now get an extra 120 miles average per 13 gallon tank of fuel. Before it would cost me and additional $12 - $14 dollars to drive an extra 120 miles. Now I simply treat each new tank of fuel with 1oz of EnviroMax Plus!
 
You drive 55.....we'll still get their with more fuel in our tanks, a better running and performing vehicle, and a story to tell all the people who are not pleased when they pull their receipt off the gas pump after they get fuel!
 
The smoke in your mirrors is because you are not using EnviroMax Plus. The product reduces emmissions by as much as 80%. And, if you could drive faster than 55 - the smoke your vehicle is putting out would not be able to be seen in your mirror!
 
I have nearly 500 customers who order the product every month. Pretty strong testimony for a product that you say will not work.

Since this discussion is specifically for Duramax fuel mileage questions, you probably want to ask over in Chevy Silverado/GMC Sierra: Owber's hangout
