Classic Focus: Should I Use 92 or 95 Octane?

[DiElias]

Classic Focus uses 92 octane. The only criterion for selecting gasoline grade is the compression ratio of the car's engine. Generally, the higher the compression ratio of the engine, the smaller the volume of the combustible mixture compressed, resulting in more power and lower fuel consumption. The commonly referred 92 and 95 octane numbers represent the gasoline grade, which is the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the grade, the stronger the anti-knock performance. The dimensions of the Focus are 4647mm in length, 1810mm in width, and 1468mm in height. The new Focus is equipped with 1.0T and 1.5T engines, with the 1.0T engine having a maximum power of 94kw and the 1.5T engine a maximum power of 135kw. In terms of the transmission system, the engine is matched with an 8-speed automatic transmission and offers three driving modes.
