What is the difference between Shell HX7 and HX7 Plus?

[StJocelyn]

Here are the differences between Shell HX7 and HX7 Plus: 1. Price: HX7 Plus is a fully synthetic oil, while HX7 is a semi-synthetic oil. From the perspective of raw materials, fully synthetic oil is made from the better components of crude oil, so its price is naturally higher than that of semi-synthetic oil. 2. Performance: Engine oil is made from base oil and additives, with the base oil determining the basic properties of the lubricant, and the additives compensating for and improving the shortcomings of the base oil. Therefore, as a fully synthetic oil, HX7 Plus outperforms the semi-synthetic HX7 oil in terms of performance. 3. Replacement cycle: Generally, the replacement cycle for fully synthetic oil is 10,000 kilometers or one year, while for semi-synthetic oil, it is 7,000 kilometers or 7-8 months. However, HX7 Plus is somewhat lacking in the replacement cycle, which is similar to that of the semi-synthetic oil HX7.
