Will this help stop any valve train components from making sounds? Like ticking coming from the valve train?

It stopped my car from running, altogether, and cost $1000 for a complete bypass of the system to be installed after cleanout. So yeah, it would probably stop your engine from making any sounds.

Es bueno para motocicleta

No es bueno por que el aceyte se ase más espeso y el motor de la motocicleta es pequeño y no funcionaria

Que cantidad se debe hechar po cada cambio
