Liqui Moly Optimal 10W-40

Description

Liqui Moly Optimal 10W-40 is a semi-synthetic all-season engine oil for petrol car engines, including high-revving and turbocharged ones.

It carries API SL and CF and ACEA A3 and B3. It holds no official approvals; the manufacturer states that it meets the requirements of MB 229.1 and recommends it for AVTOVAZ (Lada) vehicles.

Typical data-sheet figures: viscosity 14.5 mm²/s at 100 °C, viscosity index 160, HTHS at least 3.5 mPa·s, pour point -36 °C, sulphated ash 0.9-1.5 %, base number 10.3. Pack sizes from 1 to 205 litres.

Application

All-season use in petrol car engines, including high-revving, multi-valve and turbocharged units.

Worth knowing

The diesel codes B3 and CF appear in this oil’s list of classes, yet the application section of its data sheet names only petrol engines. The CF class, as the article on API CF explains, describes oils for indirect-injection diesels, and API now classes it as obsolete. The data sheet draws no separate diesel recommendation from these marks and leaves the choice to the carmaker’s instructions.

Among the Optimal oils in the catalogue only this one is semi-synthetic, and only this one has API SL, while the rest have API SP. All the typical figures, from 14.5 mm²/s at 100 °C to a base number of 10.3 mg KOH/g and Noack of 10 %, match Leichtlauf Performance 10W-40; the only code that one lacks is API CF, although its data sheet names both petrol and diesel engines. MB 229.3 and VW 505.00 are not in the Optimal 10W-40 data sheet: they are recorded as official approvals, for example, for Leichtlauf 10W-40 of the same viscosity, which has ACEA A3/B4 and API SP and also declares MB 229.1.
