viscosity at -40°C and therefore not meeting the requirements of an SAE 75W grade as defined in the SAE J306 standard. However, VLS found that the product was in compliance against the SAE 90 Kinematic Viscosity (KV) at 100°C limits. (13.5-18.5 cSt). The Named Party was asked what steps they would be taking to bring the product into compliance.
The Named Party has changed its supplier since the product was blended in 2020 and filled in 2021. They have also changed their filling procedures and moved to automated blending which they believe has solved the issue, which they believe was due to batch contamination, as the batch VLS tested was blended and filled before automated blending was introduced. The Named Party has also checked all batches subsequently manufactured and stated that they are all compliant according to their testing.
VLS undertook a six-month review of the case as part of which a new sample was tested and found to be in continued compliance and therefore the case was closed.
VLS 010186 – Valvotech 75W-90 Semi-Synthetic Gear Oil
On 15/03/2023 the case was accepted by VLS.
The complaint concerned 75W compliance at -40°C as per ASTM D2983 - Standard Test Method for Low
Temperature Viscosity using a Rotational Viscometer (Brookfield). The complainant sourced and tested the product and claimed that it was not possible to obtain a result as the product set solid during the test. The result, they claimed, showed the product was not 75W compliant and would therefore not provide adequate circulation in gear systems.
VLS independently procured a sample of the product within the UK, and tested it for low temperature properties against ASTM D2983. The test results show that the product turned solid at low temperature and therefore was not compliant with SAE J306 for a 75W product of this type.
The Named Party immediately quarantined the product, arranged for an uplift by their supplier for further investigation and testing.
VLS believes that the actions taken by the Named Party have brought the product into compliance and therefore the investigation is closed subject to a six-month review in line with VLS’s stated process. VLS undertook a six-month review of the case in line with its’ stated process. The product was found not to be on open sale in the UK and so the case is closed.
