Many diesel owners are aware that diesel is not the high-quality product it once was. A lawsuit claiming that the Bosch CP4 high-pressure fuel injection pump installed within a variety of diesel vehicles is failing prematurely. Many are questioning the use of the CP4 and how to avoid becoming another statistic of costly repairs. Luckily you don’t need to spend thousands of dollars to avoid failure with a high-quality fuel additive like LX4 Lubricity Extreme and our fully-formulated Everyday Diesel Treatment that has LX4 infused in the formulation.
