I watched a show one time on tv that tested many of these devise and noticeed all were "Snake OIl" . I just found another one < majornews.com> that really makes sense, does anyone know a site that test these things, or is just a tune up or less HP still the best answer?

true gas mileage is a mix of driving habits,terian, altitude, maintanance, tire pressure, vehicle and engine size,number of gears, final drive ratio.
EPA resently admitted that their formula for gas mileage is way off. it did not consider real world conditions and applications

I have heard you will get only 1 or 2 miles extra. And you would have to have a 40-60 gal. water tank in the car. So they are not that efficient yet. I am gona keep a better eye out in the next few years. You might like this web site:

you ought to close it off and coast down hills :). As for the O2 sensor, only because of the fact it mentioned O2 sensor code, doesnt continuously advise its a foul sensor. there may well be different issues that reason the PCM to think of the O2 sensor is undesirable. vehicles are no longer clever and cant think of. they have enter and output units that work together. there are a ton of issues that could reason collateral hardship codes. your superb guess is to have it professionally clinically determined. Im specific your brothers advise nicely, yet you cant place self belief in a code as a prognosis. Codes only propose of a situation in a particular gadget, no longer which section has failed continuously.

Cutting Gas Mileage in half, is kind of hard to do but try driving faster, accelerate harder from stops, use lower tire pressure than recommended, this should lower your mileage by at least 1/3

If you want to cut your gas mileage in half, get a bigger engine, high performance parts, and lots of intake mods!.
Or just buy an old cadillac, that will cut your gas mileage more than just half (assumin you are getting 20mpg, Half of that is 10, which is about right for an early 70`s 8.2 Liter engine.

just go to a repair shop and tell them you need a fuel system cleaner, and have them do an emissions system cleaner as well, that is the best way I know of. Maybe change the fuel filter and check your spark plugs.

When ever gas prices to up, they come out. Magnets to make the molecules line up better, water vapor injectors to make it run cooler, etc. etc.
Snake oil.
