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
