Modern engines are designed around precise lubricant properties. Using an oil with the exact vehicle maker approval supports fuel economy, protects after-treatment systems, and keeps warranty compliance intact. Sinopec engine oils carry approvals aligned to European and global standards. They are available in the UK through Sinopec Online. Open Engine Oils from the main menu at Sinopeconline.com.
What an OEM approval really is
An approval is a formal listing issued by the manufacturer after laboratory and field testing. For Mercedes-Benz, examples include MB 229.51 and MB 229.52 for low SAPS multigrades used with particulate filters. Other makers publish similar lists. Use the sheet number in the handbook and match it exactly.
Why the specific sheet matters
- Emission system protection. Low SAPS chemistry helps keep DPF and SCR hardware clean.
- Fuel economy. Friction control and shear stability contribute to reduced consumption where the sheet demands it.
- Durability. Deposit control and wear performance help with extended drain intervals.
Standards you will see with approvals
European market oils also list ACEA categories. Makers then add their own limits for volatility, shear, and sulphated ash. When in doubt, follow the strictest requirement and the exact approval code. Mixing families is unwise unless the maker permits it.
Applying this to fleet operations
Light commercial fleets often need different sheets to heavy duty diesel vehicles. Keep a register by plate or VIN with the oil sheet and viscosity. Verify your service fill against the current data sheet before ordering. Sinopec product data lists approvals and test methods so checks are fast and clear.
Maintenance that supports approvals
- Use the viscosity grade specified for the engine and the climate.
- Do not mix oils from different approval families unless allowed in writing.
- Base extended intervals on oil analysis trends, not guesswork.

Frequently asked questions
Is MB 229.51 the same as MB 229.52
No. Both are low SAPS, but 229.52 adds further targets for fuel economy and after-treatment durability. Follow the sheet in the manual.
Can I use an ACEA category if I cannot find the OEM sheet
Only if the manufacturer confirms it. The exact approval is the safe choice.
