Mobil Extended Performance Full Synthetic Motor Oil 5W-20, 5 Quart — Up to 25,000-Mile Protection

Mobil 1 Extended Performance 5W-20 is a full synthetic motor oil designed to protect engines and maintain cleanliness for up to 25,000 miles or one year between oil changes.

Mobil 1 Extended Performance 5W-20 blends advanced synthetic base stocks with targeted additives to reduce deposits, resist oxidation, and support reliable cold starts. Formulated to meet ILSAC GF-7 specifications, this oil balances wear protection, low-temperature pumpability, and deposit control so modern engines perform efficiently across a range of driving conditions.

How does Mobil 1 Extended Performance 5W-20 protect my engine over long oil-change intervals?

This formula uses specialty components that resist sludge and varnish buildup while maintaining a protective film on critical parts. That helps preserve timing chains, bearings, and piston rings during extended drain intervals without sacrificing performance.

• Advanced synthetic base stocks resist thermal breakdown and oxidation.
• Detergent and dispersant additives minimize deposit formation.
• Wear inhibitors maintain a protective lubricant layer on metal surfaces.
• Tested for protection up to 25,000 miles or one year, whichever comes first.*

Will this 5W-20 oil improve cold starts and everyday drivability?

Yes — the 5W rating means the oil flows readily at low temperatures, improving oil circulation during cold starts and reducing engine wear on startup. In everyday driving it sustains stable viscosity to support smooth operation and consistent performance.

• Low-temperature fluidity enhances immediate oiling at startup.
• Stable high-temperature viscosity protects under load and heat.
• Formulation helps maintain fuel-efficiency characteristics compared to conventional oils.***

Is Mobil 1 Extended Performance compatible with my vehicle and maintenance needs?

Mobil 1 Extended Performance 5W-20 meets ILSAC GF-7 specifications and is suitable for many gasoline-powered passenger cars, crossovers, and light trucks that call for 5W-20 viscosity. Always check your owner’s manual for the manufacturer’s recommended oil grade and service intervals.

• Meets ILSAC GF-7 performance standards for modern engines.
• Suitable for vehicles specifying SAE 5W-20 synthetic oil.
• Works with a broad range of engine ages—new or high-mileage—when the correct viscosity is specified.

What real benefits will I notice after switching to this synthetic oil?

Switching to Mobil 1 Extended Performance 5W-20 typically results in reduced deposit buildup, stable performance under higher heat, and improved protection for timing chains and other critical components. Over time you may also observe steadier fuel economy and longer intervals between oil changes when following the product’s drain guidelines.

• Cleaner engine surfaces after a change helps maintain efficiency.
• Enhanced oxidation control supports oil life and performance.
• Protection against pre-ignition and timing-chain wear in applicable engines.

Who is this for: Mobil 1 Extended Performance 5W-20, 5 Quart is aimed at drivers who want premium full-synthetic protection and the option of extended oil-change intervals when compatible with their vehicle’s specifications. It’s a fit for owners of gasoline vehicles that require 5W-20 viscosity, drivers seeking advanced deposit control and oxidation resistance, and anyone who prefers a widely recommended, retail-leading motor oil brand for routine maintenance.
