Full Syn Oil Dexos 1 5w30 1 Qt

ENEOS Full Syn Oil Dexos 1 5W30 is engineered for modern gasoline engines that demand GM Dexos 1 specification compliance. This premium synthetic 5W30 formulation delivers year-round protection in both cold-start and high-temperature conditions, making it the ideal choice for mechanics and DIY enthusiasts performing regular maintenance or rebuilds on domestic and import vehicles. The 1-quart bottle provides convenient top-off capacity for checking and maintaining proper oil levels between full fluid services.

ENEOS synthetic technology minimizes viscosity shear and delivers superior film strength across the entire operating range, protecting critical bearing surfaces, valve trains, and piston rings. The 5W viscosity at startup ensures rapid circulation in cold climates, reducing wear during cold cranking, while the 30-weight base maintains stable viscosity at sustained highway temperatures. This formulation exceeds GM Dexos 1 standards for low-SAPS (sulfated ash, phosphorus, sulfur) content, ensuring compatibility with modern catalytic converters and variable valve timing systems without deposit buildup.

Technicians and vehicle owners working on late-model GM, Chevrolet, GMC, and Cadillac powertrains will find this synthetic oil essential for maintaining manufacturer warranty compliance and optimal engine longevity. The compact 1-quart container is ideal for emergency top-offs during long-term storage, track days, or when performing extended interval synthetics on high-revving engines. Store in a cool, dry location and verify your vehicle's service manual for Dexos 1 approval before use; compatibility extends across most 2011+ GM engines and selected domestic platforms requiring full synthetic 5W30 specification.
