Castrol EDGE Extended Performance 0W-20 is Castrol’s long-interval full-synthetic 0W-20. In the 0W-20 tab of Castrol’s US product page, everything is listed under Meets or exceeds industry standards: API SQ/SP/SN PLUS/SN, ILSAC GF-7, ACEA C5, Fiat 9.55535-CR1 and 9.55535-GSX, GM dexos1 Gen 3, MB-Approval 229.71, Ford WSS-M2C947-B1 and WSS-M2C962-A1, and Jaguar Land Rover STJLR.03.5006.

dexos1 Gen 3: GM’s own licensed list (GM dexos1 Gen 3 licensed brands list) includes Castrol EDGE Extended Performance 0W-20 (license D355BIDC082), so dexos1 is shown as a license. Because Castrol lists MB 229.71 in the same “meets or exceeds” block, it is shown here as a claim rather than a confirmed Mercedes-Benz approval.

OEM specifications and approvals

Officially approved

Listed as formal approvals or licenses by the oil maker's documentation or the automaker's own approval list (the product description above names the source) — not a general recommendation.

Meets / recommended for

These specifications are listed by the manufacturer as met or recommended, which is a lighter claim than a formal, numbered approval.

Is this oil compatible with your car?

Viscosity alone does not determine whether an oil is right for your engine. Compatibility depends on the exact OEM approval your manufacturer requires, your engine's build, the model year, and the market the car was sold in — the same nominal viscosity can carry different approvals in different regions. Check your owner's manual or use OilFinderPro below to confirm the requirement for your specific vehicle before buying.

Oils sharing one or more specifications

Each row shows the exact specification two products share and whether it is a formally licensed approval or a lighter "meets requirements" claim on each side — those are not equivalent, and sharing a specification does not by itself make two oils interchangeable in your vehicle.
