Hi Pedro1981, the additives do not believe it, the only thing the only thing they do is mix it with bio, so they reduce the ketane and "adulterate", about bombs, there is not much out there, it seems reserved matter and almost nobody teaches, what I did was lower a manual of wake of Lucas cav from a DCP, there is only the location of the pieces. Those of the lid, but the lid is usually worn by the axis, if you can get one of a scrapping, the pulley retain will tell you that I know one that preferred to change the engine, he told me that they charged him less than repairing in Bosch, he holds there is almost to wake it up and there and there you can fuck it, both for the tricks that he carries, as for cleaning and precise Escape, make sure that you do not lose there, that it does not stain belt distribution, if so, it would have a clearance in the internal bearing, and this is no longer any anymore ... go for the lid that are 1.50E the toricas and it does not need or disassemble it from the car
