Sinclair OPALINE Synthetic Blend 5W-30 Motor Oil 1Qt

Sinclair Lubricants’ OPALINE Synthetic Blend 5W-30 Motor Oil is engineered to meet the increased demands of today’s gasoline-powered vehicles. Formulated with quality synthetic blend base oils and advanced additives, it helps protect engines against wear, corrosion, thermal breakdown, and sludge formation. OPALINE motor oils are designed for use in passenger cars, vans, CUVs, SUVs, and light-duty trucks, helping extend engine longevity by effectively lubricating critical components under both regular and severe driving conditions. This formulation helps protect against low-speed pre-ignition (LSPI), supports modern emission control systems, and maintains performance in vehicles operating on gasoline or ethanol-blended fuels up to E85. It meets or exceeds ILSAC GF-7A and API SQ performance standards and is fully back-serviceable to earlier specifications where applicable. For best performance, always follow your vehicle manufacturer’s recommended viscosity grade and oil change interval.
