JLM Diesel Performance Fuel System Cleaner is a professional-grade additive developed to tackle sluggish performance issues and restore lost power in diesel engines. Building on the proven base formula, this enhanced version goes further with stronger detergents and combustion enhancers that deliver a deeper, more aggressive cleaning action. It’s the ideal choice for vehicles suffering from reduced throttle response, higher fuel consumption, or minor smoke problems.

This advanced cleaner penetrates the fuel system from injectors to combustion chambers, dissolving stubborn carbon, gum, and varnish deposits that ordinary additives leave behind. By removing heavy build-up and improving combustion quality, the additive brings back smooth acceleration, sharper throttle response, and overall performance.

Engines free from deposits burn diesel more efficiently. Regular use of JLM Diesel Performance Fuel System Cleaner helps reduce fuel consumption and operating costs. Excess deposits contribute to incomplete combustion and visible exhaust smoke. This cleaner supports cleaner burning and helps engines run within emission limits for longer.

Unlike preventive additives, this formula is designed to solve problems—making it perfect for high-mileage cars, heavy-duty vehicles, or any diesel showing signs of power loss and inefficiency.

Diesel engines working under tough conditions, such as urban stop-start driving, commercial use, or extended mileage—are more prone to severe deposit build-up. Over time, this leads to sluggish performance, poor fuel economy, and rising emissions. JLM Diesel Performance Fuel System Cleaner directly addresses these problems with a stronger cleaning package that restores engine health and responsiveness.

It’s especially suited for vehicles with common rail injection, turbochargers, or those regularly driven in demanding conditions where standard preventive cleaners are not enough.
