Lubrizol has released a new white paper highlighting the potential risks associated with self-declared “Suitable for Use” (SFU) engine oils, cautioning that these products may fall short in performance and compliance when compared to lubricants carrying formal OEM approvals.
Titled “The Importance of Testing: Analysing Quality, Validation Processes and Reliability,” the white paper draws on Lubrizol’s in-house bench and engine testing, along with insights from industry bodies such as ACEA, ATIEL, EELQMS, and the UK’s Verification of Lubricant Specifications (VLS) scheme.
SFU Claims vs OEM Approvals
The report examines a growing trend in the European lubricants market—the increasing use of claim-based terminology such as “Suitable for Use,” “Meets requirements of,” and “Recommended for,” often used in place of verified OEM approvals. It emphasizes a clear distinction between self-certified claims and officially approved specifications, which require comprehensive testing programs and formal sign-off from manufacturers, such as Volkswagen VW 50400/50700 and Mercedes-Benz MB 229.52.
According to the white paper, SFU claims can obscure the absence of validated performance. Since 2013, the UK’s VLS scheme has investigated over 120 lubricant cases, with non-compliance to stated specifications emerging as the most frequent issue.
Testing as the Only Reliable Benchmark
Luke Farrell, Engine Oils Product Manager at Lubrizol, emphasized that the only way to accurately compare SFU engine oils with OEM-approved products is through rigorous testing. He noted that this distinction is critical for workshops and garages aiming to protect engine performance, warranties, and customer trust. It is equally important for marketers, who must uphold brand credibility in an increasingly scrutinized marketplace.
The white paper further states that if SFU terminology is used, it should be supported by transparent data and clearly defined test results. Alternatively, marketers are encouraged to use precise language that aligns with approvals and performance levels defined under
EELQMS/Services to Associations and Industry in the Lubricants sector (SAIL) declarations.
Intended Audience
The publication serves as a practical guide for lubricant marketers, blenders, distributors, OEMs, workshops, and regulators seeking a technical and engineering-based comparison between SFU and OEM-approved engine oils. It also outlines collective actions required to maintain quality and integrity across the lubricant value chain.
The white paper is available for download on Lubrizol’s official website.
