Haval F7: Should I Use 30 or 40 Engine Oil?

[McFinn]

Haval F7 can use either 30 or 40 engine oil. The 30 oil provides stronger power at low to medium RPM but weaker performance at high RPM, with quieter engine operation and relatively lower fuel consumption. The 40 oil offers weaker power at low to medium RPM but better performance at high RPM, with slightly louder engine noise and relatively higher fuel consumption, though it provides better engine protection. Below is an introduction to the Great Wall F7: Exterior: The 2020 Haval F7 retains the space-tech-inspired aesthetic design language, with an upgraded shield-style grille and the addition of a new gold color, showcasing excellent texture and representing the most trendy design. The aggressive hexagonal grille with a matte frame and honeycomb mesh gives the front fascia a clean, sharp, and tech-savvy appearance. The floating spoiler features a novel and unique design, exuding individuality, fashion, and sportiness while enhancing the vehicle's overall sense of style, technology, and stability. It also improves recognition, reduces wind resistance, and saves fuel. Interior: The interior continues the ring-inspired smart cockpit design, now offering a new gray-black color scheme to meet diverse customer needs. The seatbacks feature a distinctive "F" logo, adding a sense of identity and exclusivity. The driver-centric wraparound design positions the infotainment screen and functional buttons toward the driver, improving ergonomics and operational convenience. This setup provides a confident and stable seating experience for drivers and passengers. [4] The T-shaped center console design follows the current trend in high-end models.
