What Does OEM Approved Mean in Lubricants?
When sourcing lubricants for fleet, commercial, or industrial use, you’ve likely come across the term OEM Approved. But what does it actually mean, and why should it matter to your business?
What Is OEM Approval?
OEM stands for Original Equipment Manufacturer. If a lubricant is OEM approved, it means the product has undergone testing and received formal approval from a vehicle or equipment manufacturer. This confirms that the oil meets the brand’s engineering and performance standards.
Examples of common OEM approvals include:
- Mercedes-Benz MB 228.51
- Volvo VDS-4.5
- MAN M 3775
Why It Matters for Fleet Operators
Using OEM-approved engine oil ensures:
- Protection of manufacturer warranties
- Optimised performance and fuel efficiency
- Reduced maintenance downtime
Is “Meets Specification” the Same as OEM Approval?
No. An oil that meets a specification may not be officially approved. OEM approval means the lubricant has passed formal testing and validation with that brand’s engines.
