How much is Adblue in SL?

no its added to a separate tank,and sprayed tiny amounts into the exhaust manifold by an injector. not a fuel additive which goes in the fuel tank.
I see so it's no big deal. Btw the DPF issue seems to be more in the ones with DPF regeneration button than the ones with auto DPF regeneration. Atleast that's how it is in Hiace. From 2013 onwards Hiace came with a button for DPF regeneration and they seem to be getting clogged easily.
Euro 6 also has DPF. Does the adblue reduce the chance of it getting clogged?
sorry I meant the NOx storage catalyst is replaced by the SCR-adblue system. Particulates still need to be taken care of by DPF. It is the only way to fulfill Euro6 emissions norm.But you have an advantage that fewer or no Lambda sensors are needed(also a part which fails prematurely) More information can be found from wikipedia German article https://de.m.wikipedia.org/wiki/Selektive_katalytische_Reduktion "By a selective catalytic reduction nitrogen oxides are removed from the exhaust gas with a high efficiency. In contrast to the diesel particulate filter (DPF), there is no additional fuel consumption. This advantage also applies to the alternative method of reducing nitrogen oxides by means of a NO x storage catalyst which, like the DPF, requires a temporary avoidance of optimum combustion conditions. The installation of an SCR NOx reduction system makes it possible to operate the engine at more fuel-efficient operating points. Consumption thus drops by between 3 and 8%, depending on the driving style."
