Mobil Mobil 1 Extended Performance Full Synthetic Motor Oil 10W-30 — 1 Quart (6-pack), up to 20,000-mile protection

Mobil 1 Extended Performance 10W-30 is a full-synthetic motor oil formulated to protect modern engines and support up to 20,000 miles between oil changes when used as directed.

Built from Mobil 1’s Triple Action+ Formula, this 10W-30 motor oil balances performance, protection and engine cleanliness for a wide range of passenger vehicles. It meets current industry specifications such as ILSAC GF-6 and is engineered to help resist oxidation, reduce deposits, and maintain viscosity across a broad temperature range, making it suitable for everyday driving and higher-stress conditions like towing or turbocharged operation.

How does this oil protect my engine on long service intervals?

Mobil 1 Extended Performance is designed to control oxidation and oil breakdown so the lubricant retains its protective properties for extended miles. By maintaining viscosity and resisting sludge formation, it helps safeguard bearings, rings, and valve train components over longer intervals.

• Engine protection claimed up to 20,000 miles or 1 year when used as directed*
• Resists high-temperature oxidation to prevent oil thickening
• Helps reduce harmful deposits and sludge buildup
• Maintains film strength for critical moving parts

Will this 10W-30 oil work in turbocharged or high-performance engines?

Yes — the formula is recommended for modern gasoline and diesel engines, including turbocharged and supercharged units. Its thermal and shear stability help protect turbochargers, timing chains, and other high-stress components under aggressive or sustained loads.

• Formulated for multi-valve, fuel-injected engines in cars, SUVs, vans and light trucks
• Provides internal engine heat protection up to 500°F
• Helps guard timing chains and reduce low-speed pre-ignition (LSPI) risk
• Supports power delivery by protecting against wear and deposits

How does Mobil 1 10W-30 perform in cold starts and fuel economy?

The 10W-30 viscosity offers balanced low-temperature pumpability and high-temperature protection. It flows readily at low temperatures for quicker lubrication at startup while maintaining a protective film at operating temperatures, which can help the engine run smoothly and efficiently.

• Cold-temperature protection down to -40°F for faster oil flow at startup
• Viscosity stability helps reduce parasitic friction and improve efficiency
• Meets ILSAC GF-6 standards aimed at fuel economy and LSPI mitigation
• Helps maintain consistent viscosity between oil changes

What approvals and real-world endorsements support this oil?

Mobil 1 is widely used and recommended by vehicle manufacturers and independent technicians, and it’s the official motor oil of NASCAR. The product meets stringent industry standards, providing assurance for compatibility with many modern engines.

• Meets ILSAC GF-6 and common OEM requirements for modern engines
• Backed by Mobil 1’s reputation and industry testing
• Trusted by mechanics and car builders for retail synthetic use
• Official Motor Oil of NASCAR, reflecting high-performance pedigree

Who is this for: Mobil 1 Extended Performance 10W-30 is a strong choice for drivers who want a retail synthetic oil that supports extended drain intervals and reliable protection across varied driving conditions. It suits owners of passenger cars, SUVs, light trucks and vans, especially those with turbocharged or higher-output engines, drivers seeking consistent cold-start performance, and anyone wanting to reduce deposit formation and maintain engine cleanliness over longer service periods.

*Protects for up to 20,000 miles or 1 year, whichever comes first. See Mobil.US for details and warranty information.
