Multigrade oils: suitable for a
wide range of temperatures
These oils comply with two SAE grades and can be used ata wide range of both high and low temperatures. Therefore, on this lubricant you'll See two numbers separated by a hyphen. One letter will be followed by a W, indicating the oil's viscosity in cold temperatures. These oils don't need changing according to the seasons, just whenever it's time for
an oil change, as they are not affected by
temperature in the same way as monograde oils. The number before the W shows the oil's viscosity at cold temperatures and the other number its viscosity at higher temperatures.
As a general rule, it is very important to follow the instructions given by the engine manufacturer determine the most appropriate oil viscosity graae for lubricating the engine. The choice depends on the engine design, external temperatures, and what
the vehicle is used for.
