Funciona!!!
Magnífico. Tengo una de mis motos con casi ya 40 años y algunas fugas de aceite motor severas. No era una gotita, era ya casi pequeños charcos. Decidí probar este mejunje y el resultado es de 10. Han desaparecido por completo. No hay fugas ni gotas ni nada de aceite ya bajo la moto. Cuesta creer en estos productos milagrosos, de hecho no creía en ninguno pero como tenía mucha pereza y poca pasta para levantar el motot y gastar más de 200€ en juntas decidí probar por las reseñas positivas que leí a ver que tal en mi moto y si! Funciona 🙂 Apto para motores con embrague en baño de aceite o sea que lo puedes poner en tu moto sin problema... 😜

Worked quickly!!
Love this product. My 2016 Toyota Camry was burning oil. I found this on Amazon and figured I’d give it a try. To my surprise this resolved my issue! I just ordered a second bottle so I can keep up with the once a year recommendation.
