Manufacturer approval first
A 5W-30 oil without the required approval may be wrong. Match the OEM approval before comparing brands.
Engine Oil Compatibility Guide
Find oil viscosity, industry classifications and manufacturer approvals by vehicle and engine code. The correct approval matters more than viscosity alone.
Find oil for your engine
Select the vehicle and exact engine. D3 Orient will show the compatibility record and what still needs confirmation.
Compatibility result
Example result: BMW M54 oil compatibility
After search, D3 Orient shows the vehicle, engine, viscosity range, required approvals, service-fill quantity and what still needs confirmation.
Vehicle
BMW 3 Series E46 · M54B22 / M54B25 / M54B30 · 1998-2006
SAE viscosity
5W-305W-40
Manufacturer approvals
BMW Longlife-01
API / ACEA / ILSAC
ACEA A3/B4
Service-fill quantity
About 6.5 L, verify by exact model and filter housing.
Service interval
Follow the vehicle service schedule; shorter intervals may be better for age and city use.
Important note: This is a preview of the information format. Always confirm the exact approval and quantity in the manual or service data.
Viscosity is not compatibility
SAE describes cold and hot flow behavior. It does not replace API, ACEA, ILSAC or manufacturer requirements.
DPF and GPF matter
Engines with particulate filters may require low-ash oil. The wrong oil can shorten filter life.
How to read an oil specification
- SAE viscosity: examples include 0W-20, 5W-30 and 5W-40.
- Industry class: API, ACEA or ILSAC defines performance requirements.
- Manufacturer approval: examples include BMW Longlife-01, VW 504 00 or MB 229.5.
- Exact vehicle: engine code, model year, market and emissions equipment can change the answer.
Starter records are under review. Always confirm the exact oil approval, viscosity and service-fill quantity in the vehicle owner's manual, manufacturer service information or with a qualified professional before buying or filling oil.
