Liqui Moly Touring High Tech HD 30

Worth knowing

The phrase “lightly doped” in this oil’s data sheet is easily read as “almost without additives”, but the figures do not bear that out: sulphated ash of 1.2 % and a base number of 11 mg KOH/g are close to the values of the 20W-50 in the same line, and the description mentions a higher share of anti-wear components. For classic vehicles with no oil filter or with a centrifugal separator, Liqui Moly specifies another oil of this grade, Classic Motoroil SAE 30, with a very small dose of additives and ash of 0.02 %. A pour point of -33 °C does not replace a winter grade: in the SAE J300 grade table, SAE 30 has no cold limits, only viscosity at 100 and 150 °C.

Of the brand’s three single-grade HD oils (10W, 30 and 40), Volvo VDS is claimed only here, and as a Liqui Moly recommendation. In this line, Touring High Tech 15W-40 has a formal Volvo VDS approval, but it does not replace an oil prescribed as SAE 30: its viscosity grade is different, and MB 228.0 and MAN 270 are not in its list.
