The Complainant alleged that when tested the product returned the following results;
Against specification DIN 51524 Part 2:

SEB 181222
Demulsibility at 54°C, time to 40ml, minutes, max, 42/38/0: 20 minutes max.
Result: Failed
VLS procured and tested an independently sourced sample of the product and found that the product was out of specification in terms of demulsibility.
The Named Party acknowledged the out of specification test results, the batch in question was manufactured in April, since then they have changed supplier. The Named Party also confirmed that no further stock of the April batch is available in the marketplace. VLS was content to close the investigation pending a six-month review in line with its stated process.
On 20th June 2025 VLS undertook a six-month review of the case in line with its stated process.
As part of this review it procured and tested a fresh sample of the product. The test results showed that the sample was compliant for demulsibility characteristics against the performance claims made.
Consequently the case and the investigation are 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.
