2009 Mercedes-Benz G55 AMG oil capacity, type & filter

The 2009 Mercedes-Benz G55 AMG takes 9 qt of 0W-30 oil (A3/B4 required). Supported by 5 checked sources.

Applies to checked engine: 5.5L 8-Cyl.

Catalog selectors list the 2009 Mercedes-Benz G55 AMG as its own oil row, separate from nearby Mercedes-Benz model rows. In the checked rows, the checked capacity, viscosity, and filter pattern is not identical to 2009 Mercedes-Benz C63 AMG, 2009 Mercedes-Benz CL63 AMG, and 2009 Mercedes-Benz CL65 AMG. Confirm the exact model name before buying oil or a filter; similar model names can share or split catalog rows. Current-row label: model qualifier G55. Nearby catalog rows use C63; choose the matching qualifier in the seller selector.

Capacity 9 qt i Based on 1 checked source: AMSOIL Lookup. Additional cross-check is still pending: a second checked capacity source and capacity condition (service fill / with filter vs dry fill). Use it as a reference, then confirm the service-fill / with-filter amount before adding oil. See how we verify. Learn how we verify fitment

2009 Mercedes-Benz G55 AMG oil questions that affect checkout

How often should I change the oil on a 2009 Mercedes-Benz G55 AMG?

Castrol's service data indicates a 10,000 mi / 12 mo change interval for the 2009 Mercedes-Benz G55 AMG. Your actual service need depends on driving conditions and the oil-life monitor reading. Always confirm against your owner's manual; severe-duty cycles may shorten the interval.

2009 Mercedes-Benz G55 AMG oil — questions before buying

Can I use 5W-30 instead of 0W-30 in my 2009 Mercedes-Benz G55 AMG?
The checked source rows on this page list 0W-30 for the 2009 Mercedes-Benz G55 AMG. Use 0W-30 unless your owner's manual, oil cap, or service information for your exact engine allows another grade. Mercedes-Benz also requires the oil to meet A3/B4 approval — check the label on the bottle before buying. If a retailer suggests 5W-30, match the engine row first and confirm the grade before buying.
