VLS 010223 - Mannol MN TS-23 UHPD 5W-30 & MN TS-24 UHPD 5W-20
On 5th November 2024 the case was accepted by VLS.
The case concerned the claim for a formal Scania approval against the following products; Scania LDF-4 for Mannol TS-23 UHPD 5W-30, and Scania LDF-5 for Mannol TS-24 UHPD 5W-20.
It is not possible to obtain a formal approval against a Scania specification as the manufacturer only provides letters of recognition and not letters of approval against which Lubricant Marketers can claim their product meets the requirements of, or is suitable for use.
Following detailed dialogue with the Mannol the claim for a formal approval against Scania LDF-4 for Mannol TS-23 UHPD 5W-30 was withdrawn. This
product was therefore in compliance at the end of the investigation.
The claim for a formal approval against Scania LDF-5 for Mannol TS-24 UHPD 5W20 was also withdrawn subsequently and therefore the product is in compliance at the end of the investigation.
A six-month review of the case will be undertaken in line with VLS’s stated process.
On 4th November 2025 a six-month review of the case was undertaken. VLS found that the claim for approvals against Scania LDF-4 and LDF-5 had continued to be withdrawn therefore the product was in compliance at the six-month stage and the case is closed.
