The boffins at JLM identified that to achieve the best results when it comes to cleaning the Catalytic Converter on petrol and diesel vehicles it was necessary to develop a dedicated additive formula for each type of fuel. Other products rely on a single formula, sometimes presented in 2 different bottles, to treat both petrol and diesel fuels. This compromises the performance of those products as each fuel type actually requires a different set of additives in order to do the best possible job.



MOT Failure:

One of the most common causes of MOT failure is poor emissions. Yet one single treatment of either product will, in most cases, quickly cure the original cause of the problem. It will reduce the emissions to an acceptable level. Expensive repair charges are avoided.

Preventative Maintenance:

Apply one treatment of either product approximately every 5000 miles to help keep the fuel and exhaust system in good condition. This single treatment will also improve efficiency and performance and crucially will help prevent unnecessary and costly mechanical failures.
