Shell Helix Ultra Professional AG 5W-30 – Premium Synthetic Engine Oil

Purpose and Specifications

Shell Helix Ultra Professional AG 5W-30 is a fully synthetic motor oil engineered for high-performance gasoline and diesel engines, including General Motors vehicles and hybrid cars. This oil meets API SN and ACEA C3 standards, plus GM's dexos2 specification—a demanding requirement that combines General Motors' own engine tests with industry standards.

The oil is made using Shell's PurePlus Technology, which converts natural gas into synthetic base oil. This advanced formulation actively cleans engine deposits and protects critical engine parts from wear.

Key Performance Benefits:

• Fuel Efficiency: Delivers at least 1.7% better fuel economy in standardized tests, reducing your fuel costs over time
• Engine Cleanliness: Prevents piston deposits, ring sticking, and sludge buildup—keeping your engine running smoothly
• Wear Protection: Protects cam shafts, tappets, and bearings from corrosion and wear, extending engine life
• Turbocharger Protection: Safeguards turbo engines from damage caused by low-speed pre-ignition
• Low Oil Consumption: Reduces the need for frequent top-ups between service intervals

When to Use / Replace?

Use Shell Helix Ultra Professional AG 5W-30 if your vehicle manufacturer specifies API SN, ACEA C3, or GM dexos2 approval. Check your owner's manual for the exact oil grade required.

Replacement Intervals: Follow your vehicle manufacturer's service schedule, typically every 10,000–15,000 km or 6–12 months, whichever comes first. Modern synthetic oils like this one often allow extended intervals—consult your manual.

Operating Temperature Range: This 5W-30 oil flows easily at cold starts (down to approximately -30°C) and maintains protective thickness at normal engine operating temperatures (up to 100°C+).

Storage: Store unopened containers in a cool, dry place. Shelf life is typically 3–5 years when stored properly.
