Should the Edge use 92 or 95 octane gasoline?

[AlinaMarie]

The Edge can use 92 octane gasoline. The engine compression ratio of the Edge is 9.7, and generally, 95 octane gasoline is recommended for engines with a compression ratio exceeding 10. The Edge is equipped with a 2.0T turbocharged engine, paired with an 8-speed automatic transmission. This engine has a maximum power of 180kW and a maximum torque of 390Nm. It also features direct fuel injection technology and uses an aluminum alloy cylinder head and block. The dimensions of the Edge are 4878mm in length, 1925mm in width, and 1734mm in height, with a wheelbase of 2850mm. The vehicle adopts front-wheel drive, with a MacPherson independent suspension at the front and a multi-link independent suspension at the rear.

As a veteran Ford owner with three models under my belt, I've studied the Edge's fuel cap that says '92 octane or above'. Ford's 2.0T engine has a 10:1 compression ratio, making 92 octane perfectly adequate. During my last dealership visit, technicians confirmed the engine was designed considering China's fuel quality - 92 octane won't trigger warning lights. But if you hear knocking when climbing hills with AC on in summer, that indicates detonation; try switching to 95 next time. I routinely use 92 for city driving and reserve 95 for highways, since the 0.8 RMB/liter premium for 95 octane adds up to a maintenance service over time.
