Description

BP Visco 2000 20W-50 is a high-viscosity engine oil from the Visco 2000 line, intended for petrol engines of older design.

It is classified to API SG only, a category long since superseded by newer petrol categories. It therefore belongs only in engines whose maker specifies API SG or an even older class. The data sheet lists no ACEA classes and no official vehicle manufacturer approvals.

Typical figures from the data sheet: kinematic viscosity 19.3 mm²/s at 100 °C and 171 mm²/s at 40 °C, viscosity index 130, pour point -30 °C, flash point 209 °C, sulphated ash 0.77 %.

Application

Older petrol engine designs whose maker calls for API SG or an earlier category.

Worth knowing

SG, the only petrol category claimed for this oil, is classed by API as obsolete: like all classes up to and including SH, it may not give a modern engine adequate protection. Which engines SG was meant for and which earlier classes it replaces can be seen in the description of the API SG class. BP Visco 3000 20W-50 offers a newer petrol category in the same 20W-50 grade: API SL, which, according to the class description, can also be used where SJ or earlier categories are recommended. Its sulphated ash is 1.1 % against 0.77 %.

The other four oils of the Visco 2000 line claim API SP and belong to SAE 30 or 40. A kinematic viscosity of 19.3 mm²/s at 100 °C puts this oil within SAE 50, which runs from 16.3 to less than 21.9 mm²/s, and its pour point, -30 °C, is the highest in the line: the other Visco 2000 oils range from -36 to -42 °C.
