Description

BP Vanellus Multi 20W-50 CF-4 is an engine oil from the Vanellus line for diesels of every aspiration type, naturally aspirated or pressure-charged, including where fuel quality varies.

It is rated API CF-4, meeting the baseline level of that category; it carries no official carmaker approvals.

Typical figures: kinematic viscosity 20 mm²/s at 100 °C and 179 mm²/s at 40 °C, viscosity index 129, base number 7.2 mg KOH/g, sulphated ash 0.94 %, pour point -32 °C.

Application

Diesel engines with or without pressure charging, including those running on fuel of varying quality.

Worth knowing

The CF-4 mark in the name corresponds to a class under which API no longer licenses new oils. For an engine designed for CF-4, API also allows the later classes CH-4, CI-4 and CJ-4, so two more 20W-50 oils in the Vanellus line suit it: Vanellus Multi 20W-50 with API CH-4 and Turbo 20W-50 with CI-4. It does not work the other way round: where the manual requires CH-4 or CI-4, this oil does not have the required class. The article on the API CF-4 class explains which API classes are accepted as replacements and why FA-4 is not suitable for such an engine.

Its kinematic viscosity at 100 °C is higher than that of the other two 20W-50 oils: 20 mm²/s, whereas Multi has 18.4 and Turbo 19.6. Its sulphated ash is lower than that of Multi 20W-50: 0.94 % against 1.17 %. For cold starting BP gives a CCS of 7200 mPa·s (-15 °C).
