Frequently asked questions
Is J02260 compatible with OEM 83192208040 for BMW-Mini?
Yes, J02260 is compatible with OEM 83192208040, which is for Powerflex Eolys. It can be used as a replacement with JLM J02260 refill fluid.
Can J02370 help with a blocked catalytic converter on a Berlingo?
Catalytic converters cannot be cleaned in situ with chemicals. Products claiming to clean them are meant to impact tailpipe emissions, not the converter itself. J02370 ERT or Diesel Extreme Clean may help minimally, but the best solution is removal and mechanical cleaning or replacement. Using additives as a first attempt is more cost-effective.
Can JLM products help clean an oxygen sensor, or is replacement required?
Oxygen sensors can be cleaned using brake cleaner, EGR cleaner, or Direct Injection Cleaner aerosol. However, carbon build-up can be persistent, and replacement is often recommended.
Will JLM BluBoost dissolve existing crystal formations in the AdBlue system, or is it preventive?
JLM BluBoost cleans and prevents crystal formation in the AdBlue dosing system. It also conditions AdBlue for proper functioning and helps prevent performance loss and expensive repairs. If a mechanical defect caused crystallization, repair is necessary alongside using BluBoost for future prevention.
Can a diesel fuel with a sulfur concentration higher than 10 mg/kg damage a DPF?
JLM products comply with European fuel standards. Countries with high sulfur diesel require high TBN engine oils to neutralize acids, which affects the engine, not the DPF. Oils lacking Low Saps or Mid Saps can impact the DPF.
Do JLM additives improve the performance of a high-pressure diesel fuel pump?
J02330 Rapid is effective for both pumps and injectors.
Can the Extreme Cleaner and DPF Cleaner be used together?
No, combining fuel additives may have adverse effects, including overdosing. They should not be used together.
Can the Diesel Extreme Toolkit be used before the turbo on a Mazda CX3 1.5 Diesel?
It should not be applied before the turbo or via the intercooler. The correct application point is the inlet manifold.
Can DPF refill fluid be used in light trucks like the Peugeot Partner?
The vehicle type is not relevant. JLM can replace the OE fluid as long as the OE type is compatible.
Should J02210 be used with a full or half tank of diesel?
J02210 should be added to a full tank of diesel for best results. A long highway drive will help the particulate filter regenerate.
Can the JLM Diesel Extreme Clean be used for an 80L diesel tank on a MAN truck?
The non-heavy duty version is sufficient for an 80L tank. The Heavy Duty version is designed for larger trucks and machinery and could cause overdosing if used in this case.
Is the DPF refill fluid compatible with Feelpure DPF systems?
JLM cannot confirm compatibility with Satacen 315 or Pirelli FBC, so using the fluid is not advised.
Can the JLM Diesel Particulate Filter/DPF Spray be applied via the lambda probe opening?
If access through the pressure sensor hole is not possible, the lambda probe opening may be used, provided it's close enough to the particulate filter.
Will Diesel Extreme Cleaner be effective on a 1.2 TDI Polo for long drives?
A long 200 km highway drive is ideal for regeneration. If the particulate filter light is off after using Diesel Extreme Cleaner, a less strong and more cost-effective product like JLM Diesel ReGen Plus is recommended for future maintenance.
Does JLM BluBoost prevent AdBlue freezing at low temperatures?
While the chemical formulation of AdBlue limits adding other components, BluBoost contains anti-foaming additives effective in cold temperatures.
