Castrol EDGE 5W-30 Full Synthetic Motor Oil, 1 Quart Pack of 6 — Advanced Wear Protection

Castrol EDGE 5W-30 is an advanced full-synthetic engine oil engineered to reduce wear, maintain stable viscosity, and support consistent engine performance under high stress.

This Castrol EDGE 5W-30 1‑quart, 6‑pack delivers a factory-grade lubrication solution designed for modern gasoline engines that require a 5W‑30 viscosity. Formulated for superior thermal stability and protection, it helps manage sludge, maintain fuel economy, and resist viscosity breakdown so engines run smoothly across a wide temperature range. The product meets multiple OEM specifications and industry standards, making it suitable for many late-model cars and light trucks when 5W‑30 is specified.

How does Castrol EDGE 5W-30 protect my engine under stress?

EDGE uses a full-synthetic base and targeted additives to provide film strength that helps prevent metal-to-metal contact during heavy loads and high temperatures. The formulation is tested for high‑stress conditions to preserve moving parts and reduce wear across the engine.

• 3x stronger than leading full synthetics for reduced wear*
• 10x better high-stress performance to maintain film protection**
• Advanced anti-wear additives for critical bearings and camshafts

Will this oil help my vehicle maintain fuel efficiency?

Yes—Castrol EDGE 5W‑30 is engineered for low friction and consistent viscosity, which supports smoother operation and better fuel economy compared with thicker or degraded oils. Reduced internal drag helps the engine run more efficiently across daily driving and highway conditions.

• Low-viscosity flow at cold starts for quicker protection and efficiency
• Stable high-temperature viscosity to prevent thickening and loss of economy
• Compatible with modern engine systems where 5W‑30 is recommended

How often should I change the oil when using Castrol EDGE 5W-30?

Interval recommendations depend on your vehicle, driving habits, and manufacturer guidance, but Castrol highlights extended performance potential—tested for durability up to longer service intervals when approved by your vehicle maker. Always follow the owner’s manual and check oil condition between changes.

• Can support extended intervals when OEM permits — up to 20,000 miles in certain tests***
• Monitor oil level and condition, especially under severe use
• Follow vehicle manufacturer’s interval requirements first

Is this oil compatible with my car’s specifications?

Castrol EDGE 5W‑30 meets several modern industry and OEM specifications, making it a fit for many gasoline engines. Verify compatibility by checking your owner's manual for SAE 5W‑30 and approvals listed on the bottle.

• Exceeds API SQ/SP/SN PLUS/SN and ILSAC GF‑7
• Approved for GM dexos1 Gen 3 and meets Chrysler and Ford test requirements
• Suitable when manufacturer calls for a full-synthetic 5W‑30 with these specs

Who is this for: Drivers and fleet operators seeking a premium, full‑synthetic 5W‑30 oil for modern gasoline engines. It’s suited to owners who want improved wear protection, stable viscosity across temperatures, and oils that meet contemporary OEM approvals. Ideal for those who perform regular maintenance and follow manufacturer oil-change intervals, and for anyone looking for a commercially available oil that supports extended performance when permitted by their vehicle maker.
