• Viscosity basics
• The first number with “W” reflects cold‑start flow; the second number reflects hot‑running thickness.
• 0W-20 flows fastest at start‑up (great for hybrids and fuel economy), 5W-30 is a balanced all‑rounder, 5W-40 offers higher high‑temp protection for spirited driving or older engines.
• Approvals matter more than marketing
• Look for API/ACEA and OEM approvals (e.g., API SP, ILSAC GF‑6A, BMW LL‑01, MB 229.5, VW 502 00). These ensure compatibility with engine design, emissions systems, and service intervals.
• Matching use cases
• Daily hybrid: 0W‑20 with API SP / ILSAC GF‑6A.
• Modern Japanese/US petrol engines: 5W‑30 meeting API SP / GF‑6A or dexos1 Gen 3.
• Euro performance or high‑temp use: 5W‑40 with ACEA A3/B4 and OEM approvals like BMW LL‑01, Porsche A40.
• Additives and why they help
• Friction modifiers and cleaning detergents keep engines efficient and clean. Some oils feature tungsten/ceramic technology for extra wear protection.
• Service interval tips for Hong Kong
• Stop‑start traffic and short trips justify shorter intervals: 8,000–10,000 km or 12 months, whichever comes first—unless your manufacturer specifies otherwise.
• Quick checklist before you buy
• Confirm your owner’s manual spec, match approvals, consider driving pattern and climate, and buy sealed, fresh stock.
