Note: there are no English instructions. I wanted this cleaning agent to disperse throughout the nooks and crannies of the engine, so about ten minutes before arriving at the mechanic's shop for my oil change appointment, I pulled the car over and poured this into the engine, then drove it the rest of the way there. The mechanic reported lots of sludge drained out with the oil. The engine seems to perform and sound better, as if it's not working as hard.
