Description

Liqui Moly Touring High Tech Special 20W-50 is a mineral oil for high-mileage vehicles, primarily those with petrol engines. It is not intended for vehicles with a particulate filter.

Classes: API SN, ACEA A3 and B4. It holds no official approvals; according to the manufacturer, it meets the requirements of MB 229.1.

Typical figures: 19.2 mm²/s at 100 °C, viscosity index 130, HTHS at least 3.7 mPa·s, base number 10.5, NOACK volatility 3.5 %, pour point -30 °C, sulphated ash 1.3 %. Pack sizes from 1 to 5 litres.

Application

High-mileage vehicles, mainly with petrol engines, without a particulate filter.

Worth knowing

The petrol bias already shows in the codes: API is only SN, with no diesel category, ACEA is only A3 and B4, with no commercial-vehicle class E, and the data sheet singles out petrol engines. Among Liqui Moly 20W-50 oils, API SN and a claim for MB 229.1 are found only here. If your documentation requires ACEA E2 or API CG-4, those codes are in Touring High Tech 20W-50, though API SN and MB 229.1 are absent there.

MB 229.1 rests on a Liqui Moly recommendation, not a Mercedes-Benz approval. The range of vehicles for this number is narrow: the article on the MB 229.1 approval ties it to Mercedes-Benz passenger cars of 1998-2002 and lists later engines, M271 and OM646 among them, for which such oils are not recommended. Among the data sheet figures, volatility stands out: Noack 3.5 % against 5.5-7.2 % in the brand’s other 20W-50 oils, although the viscosity of 19.2 mm²/s at 100 °C lies within their range (18.5-20 mm²/s).
