[VanBrynlee]

Shell HX7 is not a fully synthetic oil. Shell Helix HX7: It is a semi-synthetic oil that focuses on cleaning performance, adopting Shell's advanced Dynamic Clean and Dispersant Technology, which provides stronger engine cleaning performance compared to ordinary mineral oils, with enhanced sludge cleaning capability. HX is the series code for Shell's oil products, and the number following HX indicates the grade of the series—the higher the number, the higher the grade. HX7 is the Blue Shell, commonly used for passenger cars, and it is the highest-grade semi-synthetic oil in Shell's product line. Shell Helix HX7 engine: It is suitable for electronically fuel-injected gasoline engines equipped with crankcase ventilation devices and catalytic converters, as well as turbocharged intercooled direct-injection diesel engines with crankcase ventilation devices. These engines typically operate under extreme temperatures and may have extended oil change intervals, which can put significant stress on the engine, leading to reduced engine sensitivity.
