How many types of Shell fully synthetic engine oil are there?

[DelNevaeh]

Shell fully synthetic engine oil is divided into two types: Shell Helix Ultra and Helix HX8. The performance characteristics of the engine oil are as follows: 1. Lubricity: The ability of engine oil to reduce friction, minimize wear, and prevent metal sintering under various conditions is called the lubricity of engine oil. 2. Low-temperature operability: The performance of engine oil to ensure easy starting and reliable oil supply in low-temperature conditions is called the low-temperature operability of engine oil. 3. Anti-foaming property: The ability of engine oil to eliminate foam is called the anti-foaming property of engine oil. When engine oil is vigorously agitated and air is mixed into the oil, foam will be generated. If the foam is not eliminated in time, it may cause problems such as air lock and insufficient oil supply.
