What are the types of Shell fully synthetic lubricants?

[LaDeclan]

Shell fully synthetic lubricants include Ultra and HX8. Shell has a classification of five different colored packaging barrels, each representing different uses and grades, and is designed for vehicles of varying levels. These are: Gray Shell, Blue Shell, Yellow Shell, Red Shell, and White Shell. More details are as follows: 1. Gray Shell is divided into Ultra and HX8, both of which are fully synthetic oils; Blue Shell is a semi-synthetic oil, Yellow Shell is divided into HX6 and HX5, where HX6 is a semi-synthetic oil and HX5 is a mineral oil; Red Shell HX3 and White Shell HX2 are mineral oils. 2. HX is the series code for Shell lubricants, and the number following HX indicates the higher the grade of the series. Common HX5 and HX6 are Yellow Helix, also known as Yellow Shell. HX5 is the highest grade of Shell mineral oil, while HX6 is a semi-synthetic oil, albeit the lowest grade among semi-synthetics. 3. HX7 is Blue Shell, commonly used for passenger cars, and is the highest grade among Shell's semi-synthetic oils. A step above is Ultra, also known as Gray Shell or Gray Helix, which is Shell's highest-grade fully synthetic oil, belonging to the hydrogen cracking + hydrogen isomerization-based Group III synthetic category.
