G-Class Engine Oil — M177 / M176
G63 AMG M177 4.0T V8 biturbo uses MB 229.51, 0W-40 or 5W-40 — higher viscosity than 4-cylinder lineup. Capacity 8.5L. G500 M176 4.0T V8 also MB 229.51. Change every 10,000 km in Malaysia's heat — V8 thermal load demands fresh oil.
Mercedes Engine Oil Grade — Malaysia
Mercedes-Benz engines require MB 229.51 (5W-30 fully synthetic) for petrol engines on modern models — do not substitute with non-MB-spec oil. The M271 1.8T W204 uses MB 229.3 (5W-40). G-Class 4.0L V8 biturbo requires 0W-40 MB 229.5 or 229.51. Using non-spec oil shortens the timing chain tensioner life and may void warranty claims. Change every 10,000–15,000 km per ASSYST — but in Malaysian city conditions, 10,000 km is the recommended maximum.
