Lucas Oil Heavy Duty Oil Stabilizer

Lucas Oil Heavy Duty Oil Stabilizer is a 100% petroleum-based formula engineered to eliminate dry starts and dramatically reduce friction, heat, and wear in any type of engine. As a pure petroleum product containing no solvents, it safely blends with all automotive lubricants — including synthetic oils, conventional motor oils, automatic transmission fluid (ATF), and mineral-based fluids — making it one of the most versatile oil additives available.

Key Features and Benefits:

• Eliminates dry starts by maintaining a protective oil film on engine components during cold starts and extended shutdown periods
• Reduces friction, heat, and wear for improved engine longevity under both normal and extreme operating conditions
• Enhances motor oil lubricity and film strength to reduce oil consumption and improve the seal between piston rings and cylinder walls
• Extends oil life by at least 50% while increasing oil pressure in worn or high-mileage engines
• Improves horsepower output and fuel economy through reduced internal friction losses
• Lowers operating temperatures for superior engine protection under high-stress conditions
• Controls noise, heat, and wear in manual transmissions, differentials, and gearboxes
• Helps reduce oil weeping and seal degradation by conditioning and restoring worn seals
