Description

Mobil Delvac 1320 (SAE 20) is a monograde oil for hard-working diesel engines, both naturally aspirated and turbocharged with intercooling. It is intended for light and heavy trucks and for construction, mining, quarrying and agricultural machinery whose maker specifies a single-grade oil.

ExxonMobil recommends it where API CF or API SF is required; the data sheet lists no equipment maker approvals.

Typical figures: 8.4 mm²/s at 100 °C, viscosity index 108, pour point -21 °C, base number 10.1 mg KOH/g, sulphated ash 1.3 %.

Application

Naturally aspirated and turbocharged intercooled diesels in light and heavy trucks and in construction, mining, quarrying and agricultural equipment where a monograde oil is specified.

Worth knowing

Among the oils in the catalogue, only this one has the designation SAE 20 with no winter index. The neighbouring oils of the Mobil Delvac 1300 series have the same set of classes, API CF and SF, but different viscosity grades. The data-sheet figure of 8.4 mm²/s at 100 °C lies within SAE 20, from 6.9 to under 9.3 mm²/s, whereas in Delvac 1330 the same figure is 11.8 mm²/s, which is already SAE 30. At 40 °C the gap is even more marked: 61 mm²/s against 106.

According to the data sheet, the thinner grade gives no lower pour point: -21 °C is the same for SAE 20, SAE 30 and SAE 40 of this series, and only the SAE 50 differs, at -18 °C. What differs is the viscosity index, 108 against 99 in the other oils of the series. The table of SAE J300 viscosity values sets out the limits of every engine-oil SAE grade, winter and summer alike.
