Trusted by professionals, it keeps engines running cleaner and more efficiently.

## Description

Review: Produit super efficace - J'étais septique sur sa et bien après avoir fait ma vidange je confirme que c le top sa nettoie super bien depuis que je l'ai fait je contrôle régulièrement mon niveaux ,l'huile est très propre donc efficace
Review: Good product - I always love castrol products. Been using them for over 5 years. Being a part time mobile mechanic castrol is all we use and this product is brilliant. Unlike many others this cleaner is PVA based and hence should not harm any oil seals.

## Features

- Modern driving creates combustion by products that can build up in your oil. When these accumulate, they build up to form layers of sludge that can harm engine performance, especially in the latest precision engines. Castrol "Engine Shampoo" helps to maintain engine power and efficiency. By adding it to the old engine oil and running the engine for ten minutes on idle before changing the oil, sludge and dirt is then removed with the old oil when changed
