Mobil Mobil 1 Extended Performance High Mileage Full Synthetic Oil 0W-20, 4.73 L — up to 20,000-mile protection, leak control

Older engines demand different care than new ones. Mobil 1 Extended Performance High Mileage 0W-20 combines a modern synthetic base with specialty additives to reduce wear, help control deposits, and improve cold-start protection. This formulation is engineered to resist oxidation, tolerate high internal engine temperatures, and meet current ILSAC GF-6 specifications so it works across a wide range of modern gasoline and compatible diesel engines.

How does this oil protect high-mileage engines?

Special additives and a synthetic base help minimize leaks, reduce sludge formation, and guard moving parts from wear. The formula is tailored to address the common needs of engines with significant mileage, helping maintain performance and reduce the risk of deposits that hinder operation.

• Seal-conditioning agents to help prevent and reduce leaks.
• Detergents and dispersants that limit sludge and varnish buildup.
• Wear-reducing additives to protect bearings, pistons, and timing components.

Will it actually extend oil change intervals?

Mobil 1 Extended Performance High Mileage 0W-20 is designed to provide protection for up to 20,000 miles or one year, whichever comes first, under recommended use. Extended intervals depend on vehicle age, driving style, and service conditions, so follow your owner’s manual and monitor oil condition between changes.

• Formulated for extended drain capability up to 20,000 miles in qualifying applications.
• Oxidation control to slow oil breakdown over long intervals.
• Maintains viscosity and detergency to keep engines clean longer.

How does it perform in extreme temperatures?

The 0W-20 viscosity grade gives fast cold-weather flow for quicker lubrication at start-up and stable protection at high running temperatures. This oil provides strong low-temperature pumpability while offering heat resistance to guard against thermal stress inside the engine.

• Cold-start protection enables quicker oil flow in subzero conditions.
• High-temperature stability to protect components at elevated engine heat.
• Viscosity control to preserve fuel efficiency and engine response.

Is this oil compatible with modern engines and performance builds?

Yes — Mobil 1 Extended Performance 0W-20 meets ILSAC GF-6 standards and is suitable for a broad range of modern gasoline engines, including turbocharged and multi-valve configurations. It is recommended by ExxonMobil for use in many passenger cars, SUVs, light trucks, and other compatible vehicles; always verify manufacturer requirements before switching oils.

• Meets industry GF-6 performance for LSPI and timing chain protection.
• Recommended for turbocharged and high-performance gasoline engines.
• Compatible with engines that specify 0W-20 synthetic oil.

Who is this for? Mobil 1 Extended Performance High Mileage 0W-20 is aimed at drivers who own vehicles with 75,000 miles or more and want the benefits of a full-synthetic oil engineered for longer protection intervals. It’s a good choice for daily drivers, long-distance commuters, and owners of turbocharged or modern multi-valve engines seeking improved engine cleanliness, robust heat resistance, and reliable cold-start performance. Always consult your vehicle’s owner manual for recommended viscosity and service intervals before use.

Note: Protection for up to 20,000 miles or one year applies under qualifying conditions; refer to Mobil.US for warranty details and specific recommendations.
