VLS Bulletin – May 2025 – Case 010205
VLS 010205 – Aztec Oils Hydratec HVI 46
On 18th June 2024 the case was accepted by VLS.
The case complaint concerned the product’s compliance with a number of specifications including DIN 51524 Part III HVLP, Dension HF-0, HF-1, HF-2 and ISO 6743-4 Type HV regarding its demulsibility and foaming characteristics.
VLS sourced and tested a sample of the product and found that its foaming characteristics were in compliance with the specifications claimed, but its demulsibility characteristics were not in compliance.
VLS wrote to Aztec Oils who responded that they believed the product formulation, both base oils and additives were correct and the non-compliance stemmed from a contamination issue.
In response Aztec Oils implemented a number of improvements planned as part of their continuous improvement plan to reduce the likelihood of cross contamination in future. They also checked their stock and distributors stock, and stated that if a customer wished to exchange their current product then they would be happy to do so, however no recall had been issued at that point.
VLS requested copies of documents sent to their distributors advising them of the non-compliance issue and their remedial action taken, and this was refused by Aztec Oils on confidentiality grounds.
A six-month review of the case will be undertaken by VLS in line with its stated process.
On 30th May 2025 VLS undertook a six-month review of the case.
As part of this review it procured and tested a new sample of the product. The test results showed that the product was compliant for foaming and demulsibility characteristics and therefore the case can be closed.
David Wright, Company Secretary of VLS said “We want to ensure we have the highest standards in Europe for lubricant manufacture, blending and marketing, and we want a ‘level playing field’ for all participants, so that we protect the interests of the consumer and other end users.
In the Verification of Lubricant Specifications (UK) Ltd, we have set our course for stronger industry self-regulation by working positively towards more open and transparent competition that benefits all lubricant organisations.”
