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.

Buen producto

Buen producto, limpia perfectamente el motor interno y se libera la suciedad en el cambio de aceite. no use todo el contenido, creo que es bueno usarlo en 2 cambios de aceite para una mayor eficiencia.

Great will use it over and over again

I will use this in every car I own from now. Cleaned it real well did exactly what it said so and my truck runs a lot better definitely can tell the difference.. it was work the extra oil and work. The bottle I bought came with instructions in English, which made it easy for me. The quality of it is light brake cleaner, but meant for engines and it ran great very easy to use this pour in.
