Description

Mobil Delvac 1350 (SAE 50) is a heavy monograde oil for hard-working diesels, both naturally aspirated and turbocharged with intercooling. It is intended for light and heavy trucks and for construction, mining, quarrying and agricultural equipment where the maker specifies an SAE 50 oil.

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

Typical figures: 19.9 mm²/s at 100 °C, viscosity index 99, pour point -18 °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

All three Mobil SAE 50 oils in the catalogue, this one, Mobil Delvac 1650 and Mobil Delvac Legend 1350, have the same set of codes: API CF and API SF, with no equipment-maker approvals. Only the data-sheet figures tell them apart.

Viscosity at 100 °C is close in all of them: 19.9 mm²/s here and 19.5 mm²/s in the other two. The base number is 10.1 mg KOH/g in Delvac 1350, 12 in Delvac 1650 and 10 in Legend 1350, with sulphated ash of 1.3, 1.4 and 1.1 % respectively. The pour point is -18 °C in both Delvac oils and -15 °C in the Legend, and the flash point of Delvac 1650 is 290 °C against 260 °C for this oil. The article on the API CF class sets out the requirements of this diesel class, shared by all three, and the current classes that replaced it.
