Mobil 1 Extended Performance Full Synthetic Motor Oil 5W-30 — 1 Qt (6-Pack), 25,000-Mile Protection

Mobil 1 Extended Performance 5W-30 is a full synthetic motor oil engineered to protect engines and maintain cleanliness for up to 25,000 miles or one year between oil changes.

Built from Mobil's advanced synthetic base stocks and specialty additives, this Extended Performance formulation targets long-term protection, deposit control, and reliable cold-start performance. It meets ILSAC GF-7 standards and is designed for modern gasoline engines that require a 5W-30 viscosity. Packaged here as six 1-quart bottles, this kit gives you enough high-performance oil for routine maintenance or multiple top-ups.

How does this oil protect an engine over long service intervals?

Mobil 1 Extended Performance uses a balanced blend of detergents, dispersants and anti-wear additives to reduce sludge and deposit formation. The formulation resists oxidation and breakdown so viscosity and protective films remain stable over extended miles.

• Guards against deposits and sludge buildup for cleaner internals
• Formulated to tolerate up to 25,000 miles or one year per fill
• Oxidation control helps preserve oil viscosity and lubricating film

Will my car start reliably in cold weather with 5W-30 Mobil 1?

Yes — the 5W cold-rating indicates easier flow at low temperatures, aiding quick oil circulation at startup. Faster flow reduces initial wear and improves protection during the critical cold-start period.

• 5W rating for improved cold-start pumpability
• Low-temperature performance supports fast oil flow to bearings and cams
• Helps reduce wear during frequent winter startups

Can this oil improve fuel economy or engine responsiveness?

Mobil 1 Extended Performance is formulated to reduce internal friction and maintain cleaner parts, which can lead to modest fuel-efficiency benefits and smoother throttle response compared with worn or contaminated oil. Results vary with vehicle type and driving habits.

• Low-friction base oils can enhance engine efficiency
• Cleaner combustion-related components help preserve power delivery
• Meets ILSAC GF-7 fuel economy-related specifications

What maintenance guidance should I follow when using this oil?

Follow the vehicle manufacturer's viscosity and specification recommendations before switching. If your vehicle accepts 5W-30 and GF-7-rated oil, this product can be used for extended drain intervals up to the stated limit, provided regular inspections and diagnostics show no issues.

• Confirm 5W-30 and ILSAC GF-7 compatibility with your owner's manual
• Observe oil level and condition between long drains to detect leaks or contamination
• Replace filters at recommended intervals to maximize performance

Who is this for: Mobil 1 Extended Performance 5W-30 in the six-quart pack is aimed at drivers who want a professional-grade synthetic oil for longer service intervals — including commuters, enthusiasts who perform their own maintenance, and fleet owners seeking extended drain capability. It’s suited to modern gasoline engines that specify 5W-30 viscosity and ILSAC GF-7 compliance, and to anyone looking for a high-selling, widely recommended motor oil to keep engines clean, efficient, and protected between maintenance visits.
