Description

Liqui Moly Classic Motoroil SAE 50 is a high-viscosity mineral single-grade engine oil with a very small additive dose. It is meant for vintage cars and motorcycles without a full-flow oil filter or with only a centrifugal separator.

The oil claims no API or ACEA class and holds no carmaker approvals. Sulphated ash is 0.35 g/100 g.

Typical figures: 19.5 mm²/s at 100 °C and 220 mm²/s at 40 °C, viscosity index 100, pour point -15 °C. Available in 1 and 5 litre packs.

Application

Vintage cars and motorcycles with no oil filter or only a centrifugal (disc-type) separator, which need an unadditised or lightly additised oil.

Worth knowing

At 100 °C this oil is almost the same in viscosity as the Classic Motoroil SAE 20W-50 HD of the same line: 19.5 mm²/s against 20, both within grade 50, which, according to the SAE viscosity value table, covers 16.3 to less than 21.9 mm²/s. They diverge at lower temperatures and in what they are meant for. At 40 °C the single-grade oil is thicker, 220 mm²/s against 178, its pour point is -15 °C instead of -30 °C, and it has no W grade. The multigrade, on the other hand, carries API SC, SD, SE and CC and has sulphated ash of 0.65 % against 0.35 %, and Liqui Moly assigns it to engines with an oil filter.

Which of the line’s two single-grade oils to put in, SAE 50 or SAE 30 (11.2 mm²/s at 100 °C), the data sheet does not say: its application section refers you to the vehicle and engine manufacturer’s instructions. Among the rows missing from the product description, it also gives a coke residue increase of 1.1 g/100 g to DIN 51352 and foaming of 0/0 ml in all three sequences to ISO 6247.
