Valvoline Penetrating Oil is a high-quality pressurised lubricant intended for loosening rusted parts.
Valvoline Penetrating Oil has been specifically formulated to penetrate rust and corrosion and release fastenings. Due to its low surface tension, Penetrating Oil easily dissolves rust on seized components.
Most importantly, Penetrating Oil quickly and safely removes oxidised layers without damaging the treated parts. There are no broken studs or threads and no time wasted drilling or machining out those elements.
