what a difference !
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.

Does its job.
Always a go to before oil changes. Helps remove some extra sludge/deposits. DO NOT DRIVE OR REV THE VEHICLE WHEN USNG THE PRODUCT, only idle for 10-15 min. Ive seen reviews where people drove with it potentially ruining the engine.

Calidad de limpieza al motor
Excelente producto, lo llevo usándolo un buen tiempo, en cada cambio de aceite, limpia bien por dentro del motor. Es fácil usarlo, hecharlo donde se llena el aceite del motor, y enciende el motor espere 10 minutos, y apague el motor, y vuelve a esperar 25 o 30 minutos para que se enfríe el motor, ya cumplido lo 25 o 30 minutos sacar el aceite viejo del motor. Listo, producto muy recomendable. Excelente funcionamiento, chevy silverado 2004
