Lovely sticky slick engine lube. Great tack adherence. Pretty much the benchmark if building a fresh engine.

Le produit lui même me semble parfait pour remonter un moteur. L'huile adhère très bien aux surfaces, pas besoin d'en mettre des tonnes. On peut faire plusieurs moteurs sans problème. Le produit est visible une fois en place, on sait si on l'a mis ou pas. Le seul reproche c'est le bouchon verseur qui pourrait être plus pratique, là on a un système qui évite d'avoir un bouchon qui se balade mais c'est pas des plus pratique pour étaler du produit précisement.
