One of the latest additions to the ever-growing JLM stable of trade-trusted, workshop-standard products is JLM Petrol Extreme Clean, a powerful petrol engine cleaner formulated for modern engines.
It is the solution to late model cars and engines with severe buildup blocking problems in different parts of the fuel system. These contaminations are tough and not easily dissolved with regular fuel additives, which is why this advanced petrol engine cleaner stands out.
The JLM Petrol Extreme Clean blend comprises multiple additives packaged into a highly concentrated 500ml super shot with one bottle treating 40-60 liters of petrol.
It is suitable for all petrol engines including direct injection with or without a turbo or catalytic converter.
Product information
Looking for the best petrol engine cleaner to restore engine power and reduce emissions? JLM Petrol Extreme Clean is a powerful solution designed to target and remove stubborn engine deposits. With a unique blend of high-performance additives, it offers unmatched cleaning performance across critical engine components.
Deep cleaning for petrol injectors, valves and combustion chambers
This advanced petrol engine cleaner contains strong detergents that clean fuel injectors, spark plugs, inlet and outlet valves, and the combustion chamber. The result is smoother engine operation, improved fuel efficiency, and reduced emissions.
An integrated octane booster also enhances combustion efficiency, making it cleaner and more complete. The combined effect of these detergents and octane booster directly reduces the buildup of carbon deposits and ensures lower emissions from the start.
Lower exhaust temperatures, cleaner turbo and catalyst
By lowering the burn-off temperature of oily residues and soot particles in the exhaust system by about 125°C, JLM Petrol Extreme Clean mimics the effects of JLM DPF Cleaner and ReGen Plus. This means:
- The exhaust system stays cleaner for longer
- Turbochargers remain cleaner and more efficient
- Catalytic converter efficiency increases
- Overall exhaust gases are significantly cleaner
Phosphor neutralisation for a healthier catalytic converter
If oil leaks into the combustion chamber, it can create phosphor during burning which harms the catalytic converter efficiency and can cause many more issues down the line. One of the unique elements of JLM Petrol Extreme Clean is that it neutralises up to 50% of this phosphor. This prevents catalytic damage, extends service life, and helps maintain optimal exhaust flow.
How to use JLM Petrol Extreme Clean
Use JLM Petrol Extreme Clean during regular maintenance or whenever you notice:
- Rough engine idle
- Turbocharger issues
- Black exhaust smoke
- Poor acceleration or engine response
Instructions
- Pour one 500ml can into a petrol tank containing 40–60 liters of fuel
