Test report No. 761523 · 15.04.2024

Water accumulation was detected. This may be due to failure to observe storage, transport or sampling procedures. The other parameters are typical of the stated oil type. More accurate interpretation of the results requires comparison with the same product of guaranteed quality, or with the full requirements for the lubricant and the quality certificate for this product.
