AFTERTREATMENT SYSTEM CLEANER
Exhaust aftertreatment system maintenance
All filters need to be cleaned or replaced at some point. In the case of gasoline particulate filters (GPF), for instance, particulates from the combustion process build up over time, despite fuels being cleaner than ever before.
In the case of diesel particulate filters (DPF), most of the difficulties experienced by the drivers of diesel vehicles are due to the way the aftertreatment system is intended to function. Short journeys and urban traffic are bad news for diesel particulate filters. The slow pace of traffic in congested cities mean that diesel exhaust gases rarely get hot enough to initiate the purging procedure.
The engine control unit will only start the purging process at exhaust gas temperatures above 650°C and herein lies the problem. If the parameters set in the engine control unit prevent the initiation of the purging process, then the procedure must be initiated manually, either by connecting the vehicle to a diagnostic computer or by means of a fuel additive.
If the partially blocked diesel particulate filter is not purged, any further accumulation of particulates will restrict the flow of exhaust gases, eventually forcing the driver to act. Failure to ensure the filter is purged leads to reduced performance, increased fuel consumption and, finally, DPF filter failure.
Ultimately, what this means for drivers of diesel-powered vehicles is that they have two choices to ensure that the filter is kept clean without a visit to the workshop. The first option is to take the vehicle on regular trips out of town, wasting time and fuel in the process.
The second option is by far the simplest and involves just pouring a tin of BIZOL DPF Regeneration + d61 into the fuel tank. Using an additive is the most convenient method of keeping the DPF free of soot and other contamination. There is no need to change driving habits and all that is needed is a tin of additive every third tankful of fuel.
Catalytic system component protection
BIZOL Catalytic System Protect+ g82 is designed to clean and protect the catalytic system including gasoline particulate filters (GPF). One application already dissolves many of the deposits, but it is advisable to use the treatment regularly to keep trouble at bay.
The need to clean and protect gasoline aftertreatment systems is more acute in regions where fuel quality cannot always be guaranteed but is actually necessary in all territories. If left unchecked a build-up of deposits will initially cause a gradual loss of power etc. Many telltale signs are ignored and put down to general wear and tear, which is the exactly why cleaning away the deposits is essential because it is far better (and cheaper) to prevent damage, than to cure it.
Problems caused by a build-up of deposits in the GPF and DPF include:
- low performance
- higher fuel consumption
- increased emissions
- poor driveability
- poor starting & idle behaviour
- emissions test failure
- check engine (MIL) light illuminates
BIZOL aftertreatment system cleaners free particulate filters of deposits. And with the deposits gone, the aftertreatment system can do its job efficiently again, cleaning the exhaust gases as originally intended.

The melodious purr of a motor, the velvety transition of cog-wheel, and the elegant voyage along the expansive highway — these are the unmistakable characteristics of a meticulously calibrated self-shifting gearbox system. But what transpires when the motorized ensemble falters, the cogs gnash, and the voyage veers into an unforeseen tempest? Get into the realm of automatic transmission problems, a domain where automotive aficionados and everyday motorists alike encounter the enigmatic intricacies of this complex system.
Driving is a blend of exhilaration and convenience, but sometimes, your trusty car can hit a snag. One of the most frustrating issues is a coolant leak.
Coolant, often referred to as the versatile 'antifreeze,' assumes the uncelebrated role of an automotive guardian, ensuring your engine's harmonious operation. This unassuming fluid stands as a bulwark against the scorching summer heat and the bone-chilling cold of winter. Nevertheless, when the vigilance of antifreeze wanes, and it embarks on an unauthorized journey beyond its confines, ominous troubles come into view.
