Do you remember the first time we had a "fuel crisis" in this country, and gas prices jumped from around .25 cents a gallon to nearly .60 cents? Remember how we complained? Wouldn't you love to have those days back again? Never again...today, for the good of the country and the planet, we must try to do more with less. For the most part, we succeed. Many of today's V8 engines get better gas mileage while delivering more power than an inline six of thirty years ago, or even a four-banger of sixty years ago.

This is due in large part to the high-tech fuel delivery and exhaust systems that work together to get the most out of every precious drop of fuel. The Mercury Villager Oxygen Sensor is part of an important part of these systems.

An ideal fuel to air ratio, or "mixture," is required to keep the engine to running at peak performance while minimizing exhaust emissions. The leaner the mixture(more air, less fuel), the lower the emissions. The Mercury Villager Oxygen Sensor actually "senses" the amount of oxygen in the exhaust as it comes out of the catalytic converter, then delivers an electronic signal to the fuel-injection system, which adjusts the mixture accordingly - essentially performing the function of the old choke knob. When an oxygen sensor is damaged or defective, engine performance will suffer, and gas mileage will fall. If you're experiencing these symptoms and all other systems check out, you may need a new Mercury Villager Oxygen Sensor.
