Lubrizol Warns of Performance Gaps in Self-Declared Engine Oils — The Lubrizol Corporation

Event summary

Lubrizol released a whitepaper on March 30, 2026, highlighting performance gaps between 'Suitable for Use' (SFU) engine oils and OEM-approved oils.
The paper cites UK’s VLS scheme investigations of over 120 lubricant cases since 2013, with non-compliance being the most common issue.
Lubrizol argues that SFU claims often lack validated performance compared to formally approved engine oils.
The whitepaper provides guidance for marketers, blenders, distributors, and end users on understanding risks associated with lubricant specification claims.

Lubrizol’s whitepaper underscores a growing tension in the lubricants market between self-declared performance claims and formally approved specifications. The push for verified testing aligns with broader industry trends toward transparency and regulatory compliance, particularly as automakers and consumers demand higher standards for engine protection and warranty coverage.
