Description

Liqui Moly MoS2 Leichtlauf 10W-40 is a semi-synthetic engine oil with the solid lubricant molybdenum disulphide (MoS2). It is intended for petrol and diesel engines and is meant to give them extra protection during start-up and warm-up, under heavy load and in stop-and-go traffic.

It holds no official approvals; the manufacturer gives recommendations only, to ACEA A3/B4 and API SL.

Typical figures: viscosity 14.6 mm²/s at 100 °C, viscosity index 165, HTHS at least 3.5 mPa·s, NOACK 10 %, pour point -36 °C. Pack sizes from 1 to 205 litres.

With sulphated ash of 1.0-1.6 %, the oil is not intended for cars with a particulate filter.

Application

Petrol and diesel engines without a particulate filter, including frequent starts, long warm-up, heavy loads and stop-and-go traffic.

Worth knowing

The word Leichtlauf links this oil with Leichtlauf 10W-40 and Super Leichtlauf 10W-40. The ACEA A3/B4 classes and the ash of 1.0-1.6 % also match, and the viscosity at 100 °C almost does (14.6 mm²/s against 14.5). Beyond that the code lists diverge: both of those oils declare API SP and hold official MB 229.3, VW 501.01 and VW 505.00 approvals. The MoS2 variant keeps only recommendations to A3/B4 and API SL, without a single carmaker number, so it does not cover documentation that calls for such a number.

MoS2 Low-Friction 15W-40 has a close viscosity, 14.2 mm²/s, and the same set of codes; the cold side tells them apart, with the 15W grade instead of 10W and a pour point of -33 °C against -36 °C. MoS2 Leichtlauf 10W-30, at 11.9 mm²/s, adds API CF. The data sheet describes this oil’s base as a blend of “mineral and synthetic base oils” without giving the proportions; the article on semi-synthetic oils explains what ratio this type of base usually means.
