LX4 Lubricity Extreme

Resolves CP4 High-Pressure Fuel Injection Pump incompatability issues with American produced Ultra-Low Sulfur Diesel (ULSD) fuel

Bosch CP4 Fuel Injection Pump Failure

A fuel injection pump supplies pressurized fuel to the injectors to facilitate combustion and power generation. The Bosch CP4 high-pressure fuel injection pump is found in a wide range of diesel engines around the world. The CP4 pump’s design enables it to handle the demanding requirements of modern diesel engines, but unfortunately, it is prone to failures under certain conditions. 

Properties of the CP4 Fuel Injection Pump

The CP4 pump is a high-efficiency replacement for the CP3 for various reasons:

  • It is made from a lightweight aluminum cast flooded with diesel to lubricate the rotating parts.
  • It has a high-pressure capacity of up to 30,000 PSI, which optimizes fuel combustion for maximum performance.
  • Its small design allows for integration into various engine setups, making it a flexible choice.
  • It hosts a fuel metering technology that controls the amount of fuel directed into the cylinders, ensuring the engine receives enough fuel for optimal combustion, increasing performance and decreasing fuel consumption.

The Solution to CP4 Pump Failure

Use Hot Shot’s Secret LX4 Lubricity Extreme

HIGHEST LEVEL OF LUBRICITY CONCENTRATION AVAILABLE

LX4 Lubricity Extreme is a premium lubricity additive for Ultra-Low Sulfur Diesel (ULSD) and gasoline. Hot Shot’s ultra-low sulfur diesel additive contains the highest level of lubricity performance on the market and can put even the poorest quality fuel back into the specification of, and exceed, OEM requirements for lubrication. Use this CP4 fuel system saver to greatly increase fuel’s lubricity and prevent the wear and scarring of key components inside the fuel system, including pumps and injectors. This diesel fuel lubricant is warranty safe and emissions equipment safe.

The Engine Manufacturers Association recommends all diesel fuel should be below the 460-micron specification to protect all fuel injection systems. 3rd party ASTM D-6079 testing of LX4 showed that fuel that was out of specification would be brought down below the 460-micron level that is necessary to protect injectors and pumps from premature failure.

By increasing the lubricity of the diesel fuel the Wear Scar Diameter is lowered. By bringing the Wear Scar Diameter back below the recommended threshold, excessive wear is prevented. Give your fuel system the protection it needs, add LX4 CP4 fuel system saver to every fill up to save you the time, headache and expense of replacing the fuel system before failure occurs.

100% compatible with other Hot Shot’s Secret fuel additives, including DIESEL EXTREME, EVERYDAY DIESEL TREATMENT and GASOLINE EXTREME. Follow recommended treat rates.
