Example, a four-cylinder engine could have two plugged injectors, while the other two may only be mildly plugged or not plugged at all. The oxygen sensor indicates to the computer that the engine is not receiving enough fuel, so it increases the fuel supply to all four cylinders. Now the two injectors that weren’t plugged are providing more fuel than necessary. As a result, it creates a situation where two cylinders are running rich and the other two are running lean. Removing fuel injector deposits allows the engine to operate as it was designed, improving fuel economy, lowering emissions and contributing to improved drivability and increased power.

Whether deposits have built up over a relatively low number of miles, or they have accumulated over 100,000 miles, P.i. fuel additive effectively removes them. Because fuel injector deposits and the associated performance issues usually build up slowly over time, motorists often attribute the decreased performance to the increased age of the vehicle. When the deposits are removed, the performance improvement is immediate and significant.
