"I have commonly seen fraud in fuel and oil testing and it plain makes me sick how they deliberately mislead the public and how some companies are spending millions to fight good mileage. This includes the American car companies because they enrich the mixture to defeat mileage gains, and in so doing they cause millions of tons of pollution (as unburned fuel) to enter our atmosphere. Look at your tailpipe. Is it covered with black soot? It is time we halt that practice.
Shown below is a little box from BrightGreen that stops a car from enriching the mixture no matter what mileage you are getting. [b]For instance a Mercedes 320 SUV in Texas on gasoline is getting 73 to 78 MPG with a device similar to one of these along with the BrightGreen Squirter and BrightGreen Warmer Devices. [/b]It inoculates your vehicle against Detroit Fever. The model shown below has a fixed signal setting. Other models have an adjustable signal so you may alter the mixture as you wish. These in effect bypass certain features of the O2 sensor in order to gain good mileage in cars that have been sabotaged by the factory. Learning is often an experience where we expose our ignorance. We have been learning a lot of new information lately regarding mileage and the O2 systems in our cars."
