High Mileage Oil Stabili zer Case 12 x 1 Qt.

High Mileage Oil Stabilizer Case 12 x 1 Qt. by Lucas Oil is a professional-grade motor oil additive formulated to restore protection and performance in engines with over 75,000 miles on the odometer. This twelve-pack bulk offering serves fleet operators, service technicians, and high-mileage vehicle owners who need reliable, cost-effective treatment across multiple vehicles. As engines age, oil viscosity breaks down and internal wear accelerates; Lucas Oil's stabilizer additive counteracts both issues simultaneously.

The stabilizer works by thickening existing motor oil to restore proper film strength on worn engine surfaces, reducing metal-to-metal contact and friction that accelerates wear in high-mileage powerplants. Each quart bottle contains a concentrated blend of viscosity modifiers and anti-wear compounds that mix seamlessly with conventional, synthetic, and synthetic-blend motor oils without requiring a full oil change. The additive reduces blow-by, minimizes oil burning, and seals worn piston rings—critical concerns in engines with significant mileage history. One quart treats up to five quarts of motor oil, making the case economical for ongoing maintenance programs.

High-mileage vehicles, commercial fleets, rental car operators, and independent shops benefit most from this case format. Technicians use Lucas Oil High Mileage Oil Stabilizer as a preventative treatment before major repairs or as a diagnostic tool to evaluate whether oil restoration can extend engine life before overhaul becomes necessary. Simply add one quart per five quarts of crankcase oil at the next scheduled oil change; no special tools or procedures required. The product is compatible with gasoline and diesel engines, turbocharged and naturally aspirated configurations, and all vehicle makes and models using standard motor oil.
