Oil Catch Tank
The Oil Catch Tank can is more of a preventative measure than an actual gas mileage booster. PCV tube stands for the Positive Crankcase Ventilation tube (PCV). It's used to vent any pressure built up in the head of the engine, but since we have emissions laws, that venting means that the gasses must be properly burned to prevent excess pollution. This is done by sending the gasses back into the engine through the intake. When this occurs not only will the engine have a pushing pressure, the intake will also have a sucking action working on the tube. This results in a force so great that gasses AND oil will be transferred from the engine and into the intake manifold. In other words, it results in burning oil.
