I run a Citroen ZX 1.9D since 1998 and been making use of the Morey Fuel
Conditioner (both the petrol & the diesel ones are ok, the diesel one has
anti fungi additive and black in color)(comes in translucent white
plastic bottle, 1 litre)
The cost per bottle is about RM30 and 1 bottle of 1 litre can treat about
400 litre of fuel.
This can buy from certain spare parts shop and sometimes in accessories
shop.
So far, no trouble with the fuel systems, touch wood, injectors, pump,
filters working ok. And no black smoke, even with our damn bad diesel
quality. The diesel fuel so bad that in long run can cause the diesel
pumps to have wear & tear and smoking like those public buses (intrakota
& metro bus euro 2 engine wor!)
I believe that maintain the diesel engine like this in the long run,
cheaper than petrol one. Except for stoopid garhmen road tax policy...
