How Valvoline High Mileage Helps Clean Sludge

1. Detergents and Dispersants

• Valvoline High Mileage Motor Oil includes special detergents that break down and suspend sludge particles and carbon deposits.
• The dispersants in the oil help keep contaminants suspended, preventing them from settling and causing further buildup in the engine.

2. Cleans and Protects

• The oil helps clean the engine while you drive and protect it from further wear and sludge buildup. This is important for engines with higher mileage that may have older seals or gaskets.

What It Doesn’t Do

• Severe Sludge: If the engine has extensive sludge buildup, simply switching to high-mileage oil may not be enough to clean it completely. In such cases, a manual cleaning or a professional flush may be necessary.
• Permanent Fix: While it helps clean minor sludge and prevent further accumulation, it isn’t a permanent solution for engines with severe sludge issues.
