same car, same commute, same tires 5mpg less this summer than last??

2005 Dodge Neon SXT 4 dr 60k ish miles new tires last summer, still 95% tread.

air filter always replaced before it needs it, its new now.

only difference I can think of is I had the tires inflated right up to the max according to the print on the sidwall of the tires. When I had them rotated I think perhaps les schwab aired them back down to 32 from 40 psi. Les Schwab says I had them over inflated (didn't account for when the tires heat up and gain pressure)

I think I'll over inflate them again, they were better in the corners that way :) prolly gain back some MPG too even if I do have to buy tires a bit sooner?

What kind of car, how old, how many miles?

First thing I would do is put new wires and plugs in, make sure they're gapped right, then I would have a shop test your O2 sensor for you. Typically an O2 sensor lasts between 100-150k miles, but it's possible one could fizzle out earlier. I do know that if your O2 sensor IS bad, you will see a significant drop in your fuel economy.


The gas I buy has techron, a gas detergent(Chevron). Wouldn't that keep my junk clean?
Like I said the tires are 95% or better
Air Filter is new
car does not stumble on heavy acceleration, so fuel filter isn't plugged.
My driving is no different then usual

This last tank I barely broke 30mpg! Way low for me.

I think there is way more ethanol than last year, was just trying to see if anyone else has noticed a drop in mileage from last summer.
 
I gave those caps an honest effort last year and saw no difference in mileage.

well perhaps it wasn't enough time ...I run in my truck and am experiencing over a 100 litres less per fill up

they are in my Bimmer, wood truck and wifes Van:beer;
 
I would check the pump to make sure you are getting the right amount of gas. Take a gallon jug with you and fill it up to make sure you are really getting a gallon of gas.
 
Complete ripoff. If you buy into this I have a bridge to sell you.

Oh yeah, and I have one of those intake tornado things to sell you as well.

hey skippy lemme give you a lil tip ...I have over 1.8 million in sales and own all of Europe with over 66,000 people world wide..

how do you like them apples LOL:beer;

With the price of gasoline reaching $3 a gallon, scammers are polluting the [COLOR=red ! important][FONT=&quot][COLOR=red ! important][FONT=&quot]market [/FONT][/FONT][FONT=&quot][COLOR=red ! important][FONT=&quot]place[/FONT][/color][/FONT][/color][/color] with gimmicks and products designed to take advantage of consumers beaten down by the high prices.
http://www.consumeraffairs.com/news04/2006/04/aaa_gas_prices.html

The pill is called MPG-Cap, marketed by Fuel Freedom International. The company says by dropping a couple of the pills, which cost $2 each, into your gas tank, you can increase your gas mile by up to 20 percent. How can that be?
"MPG-Cap is an engine conditioner that simultaneously improves [COLOR=red ! important][FONT=&quot][COLOR=red ! important][FONT=&quot]fuel [/FONT][/FONT][FONT=&quot][COLOR=red ! important][FONT=&quot]economy[/FONT][/color][/FONT][/color][/color] and power by creating a micro-thin coating on the combustion chamber in your engine allowing your fuel to burn more efficiently," the company says on its Website.
Not so fast, says AAA. The automotive consumer group took the MGP-Cap for a test drive and said it found no improvement in mileage while driving at 34 miles per hour. There was a slight gain -- four percent -- at 65 miles per hour. Even increasing the amount of the product per gas tank didn't help.

One of the latest ads sweeping the Internet is a "gas pill" marketed by Fuel Freedom International. Fuel Freedom International says dropping a $2 MPG-Cap in your tank with every fill up will increase mileage by 10 percent or 20 percent. When ABC affiliate WPVI asked a AAA expert to test-drive the pill, results were not as significant.
AAA saw no improvement while driving at 34 mph and just a 4 percent increase in mileage at 65 mph.
The company recommended a bigger dose, but when AAA used four pills in the tank, it didn't make a difference.
"I didn't see anything approaching any of the claims for 10 [percent], 20 [percent] or 30 percent improvement in mileage," said Tom McLaughlin of AAA.
The company suggested McLaughlin might have to burn several tanks of gas before the pill kicked in. Fuel Freedom International did not return "Good Morning America's" calls for comment.
The Environmental Protection Agency has not tested MPG-Caps, but it has tested more than 100 other gadgets and additives that say they will save gas and has found they do not work.
"Those kind of claims, we have yet to find any kind of device or additive that can produce that type of result," said Joni Lupovitz of the Federal Trade Commission.

whoops the last one was bio performance, not MPG cap


my bad

Dude----Keep you foot out of the peddle. I know how you and your brother drive.
My new fancy ride got 57 on the last tank. Maybe I'll have some sled fuel $$ this year.

Yea , A fight. I like it when people readjust them selves in their chair and get to use tuff words like. " Skippy".
 
Can you explain how a "mico thin coating" in the combustion chamber that is "installed" with these "pills" helps fuel burn more efficiently?

Honest question.

Honest question.

COMBUSTION CATALYST TECHNOLOGY DEVELOPED AND PROVEN: Works with: Gasoline, Diesel, Bio-diesel, and Ethanol-Gasoline blends. IFT-Liquid is a product that helps commercial vehicles increase mileage & lower harmful emissions.

IFT-Liquid is not a Fuel Additive and does not alter or modify the fuel in any way and will not harm the engine. IFT-Liquid is a engine conditioner. Continued use of the product will maintain the coating that serves as a catalyst, raising engine efficiency and gas mileage. IFT-Liquid will not harm car, truck, or boat engines. This technology has been in use for over 30 years in all types of motors and vehicles. The IFT-Liquid formula is the result of the continuation of proven space age technology at its best. IFT provides your company with significant fuel savings as well as the satisfaction that comes from reducing harmful emissions.

How Does it Work?

The IFT-Liquid compound uses the fuel (gas, diesel, or Bio Fuels) as a carrier to deliver it into the engine combustion chamber where it actually does its work. The ingredients in the IFT- Liquid are used to treat the combustion chamber metal surfaces.

A film is formed on all the surfaces. Technically, the film is thermally derived oxidation. The carboxylic metal creates an oxide residue on the hot surfaces at the time of combustion.

A simple similar example of this is the scorching of a pan when cooking. We are all familiar with how a residue from cooking will form a layer on a pan if the food is overheated. In most cooking cases, the amount of material oxidized is of sufficient quantity to form a heavy film. However, if you scrub the pan many times, the film will get so thin that all you see is discoloration with a film so thin it appears to be part of the pan impregnating the pours of the metal.

The high temperature in the cylinder of an engine combined with the small amount of material that will oxidize or carbon out produces a very thin layer very rapidly. This film coats the walls of the cylinder, the piston face, and the fire deck. Once this film is deposited, it provides several benefits. First, it changes the surface heat absorption characteristics of metal.

Note: The greatest loss in efficiency in an automobile engine is the loss of heat.

Heat is energy released by the fuel, and air mixture as it burns producing a heat spike, which creates expansion used to drive the piston down. The cylinder walls and head are water cooled, and the piston is oil cooled. The film inhibits the transfer of radiant heat. This means higher combustion temperature, greater expansion, and more power. The second positive effect of the film is the provision of a surface to more evenly distribute the fuel.

A polished surface tends to cause beading as a polished paint job. The micro film attracts the liquid fuel. More even fuel distribution better shapes the charge yielding more power. The third work of the film is being a catalyst precursor to react with the catalyst component in the IFT- Liquid. With the temperature in the cylinder and the presence of the catalyst, a catalytic reaction occurs to promote better disassociation of chemicals and better burn. The catalytic reaction is also exothermic and produces heat. The combination of all the above produces 30 to 40% more expansion in the cylinder, with an equal amount of fuel.

Changes in the automotive industry in the last 15 years have increased fuel efficiency. The EPA has mandated rules to lower emissions. Fuel manufacturers have removed lead and added oxygenates to fuel. These changes have caused modern vehicles to build harmful deposits that tend to soak up the fuel and cause performance problems. The IFT-Liquid provides a micro-thin coating that inhibits build-up of harmful deposits. An added benefit of using the IFT-Liquid lowers emissions. The catalytic process found in catalytic converters on exhaust systems is started in the firing cylinder, which reduces the formation of nitrous oxides (NOx). The work required by the converter is reduced, and life of the converter is extended.

The film produced on the cylinder walls is a continuous process and is polished by the rings on the piston becoming a more durable surface than the original metal. Less wear will occur, and extended engine life should be the result.

Since most automobile engines burn fuel at over 99% efficiency, it is impossible to improve the combustion alone. However, by using more heat of combustion, shaping the burn, and using the catalytic process to start the reaction and disassociation of chemicals usually driven by heat, a more efficient burn is produced. A burn is produced that will provide more expansion in the cylinder, therefore requiring less fuel.

The greatest positive effect is the fact that more heat produced by the combustion is being used. The extra heat causes greater expansion of gases, increasing power, and overall efficiency of the engine. Most fuel is burned to use the heat. In an automobile, the heat is basically wasted. In my past experiments and testing, I have proven heat recovery to be the only practical way to improve gas mileage on a modern engine. The process produced by the IFT-Liquid does use more of the heat generated, and the catalytic process produces additional heat. The use of IFT-Liquid is a practical way to improve mileage, increase power, and extend engine life.
 
h2 that **** is a hoax. i have a friend that spent $735,000 on infomercials and marketing and got **** out of it. it was proven it was just moth balls and some other ****. i think his brand was fyi or somthing like that. it wasn't just him it was a whole bunch of investers that lost out also. it's nothing more then a chain letter were the first guys make money and soon be sued for ripping people off.

there ya go:face-icon-small-win
 
These guys that try so sell snake oil are nuts. They sell it so they believe it. Is your car on the pill. Combustion chamber coating come on, oh the best one was the Tornado. come on who bought this? Bang the drums make people come and lie to them. I bet I am called a name on this one like skippy. Keep your car tuned and the RPMs as low as possible to get the best MPg.
