Description

Liqui Moly Optimal New Generation 5W-40 is a synthetic low-SAPS oil for petrol and diesel engines with or without a particulate filter, and for cars running on CNG or LPG. The manufacturer has tested it with turbochargers and catalytic converters.

It carries ACEA C3 and API SN/SP. It holds no official approvals and meets MB 229.31 without formal approval.

Typical figures: viscosity 14.3 mm²/s at 100 °C, viscosity index 170, HTHS at least 3.5 mPa·s, NOACK 12 %, pour point -36 °C, sulphated ash no more than 0.8 %. The data sheet gives the same figures as for Leichtlauf Performance 5W-40. Pack sizes 1 and 4 litres.

Application

Passenger-car petrol and diesel engines with or without a particulate filter, with a turbocharger and catalytic converter, and cars running on CNG or LPG.

Worth knowing

A single digit at the end of the Mercedes-Benz number separates a low-SAPS oil from a full-SAPS one here. Optimal Synth 5W-40 from the same line declares MB 229.3 and is A3/B4, with a base number of 11 mg KOH/g and sulphated ash of 1.0-1.6 %, while this oil combines MB 229.31 with ACEA C3, ash of up to 0.8 % and a base number of 8. The low-SAPS number, according to the article on MB 229.31, is intended for cars and minibuses with particulate filters, so the same SAE grade and the close 14.3 and 13.9 mm²/s at 100 °C are no reason to swap one for the other.

This oil has no MB 229.31 approval: the data sheet gives the number as a Liqui Moly recommendation. Among the brand’s 5W-40 oils it is listed as official, for example, in Top Tec 4110 5W-40: the same class, ACEA C3, but by API only SN, without SP. The status of other oils can be seen on the approval page. New Generation 5W-30 matches it on base number and Noack, lacks API SN, adds a recommendation for ACEA C2 and gives 11.8 mm²/s at 100 °C.
