20W50

20W-50 is a heavy-duty multigrade engine oil primarily used in high temperature settings. The numbers 20W-50 follow the Society of Automotive Engineers (SAE) format for multigrade engine oil, with the ‘W’ meaning ‘Winter.’

Compared to single grade oils, multigrade oils like 20W-50 offer a better operating temperature range.

Global Lubricate SAE 20W-50 is a thicker oil with high viscosity at hot temperatures and is highly resistant to oil thinning. Despite being one of the less popular oil viscosity grades, it’s still recommended for a lot of automobile vehicles.
