What grade of gasoline should a Focus use?

[Frodo]

The Focus uses 92-grade gasoline. 92-grade gasoline has an octane rating of 92 and a heptane rating of 8, making it suitable for vehicles with relatively low compression ratios. The dimensions of the Focus are 4647mm in length, 1810mm in width, and 1468mm in height, with a wheelbase of 2705mm. It has a maximum horsepower of 122ps, a maximum torque of 153nm, and a maximum power output of 90kw. The front brakes are ventilated disc type, while the rear brakes are disc type. The parking brake is a handbrake, the steering assistance is electric power-assisted, the drive system is front-wheel drive, and the body structure is of a unibody design.

I've been driving a Focus for several years and noticed the manual recommends using 92 octane or higher gasoline. I've always used 92 octane, and it runs smoothly. Never use lower octane fuel, such as below 90 octane, as it may cause engine knocking, leading to severe wear over time and expensive repairs. Once I tried 95 octane, and the power felt a bit better, but the price was higher, so I usually stick with 92 octane to save money. Also, when refueling, go to major brand stations to ensure fuel quality and avoid clogging the fuel injectors with impurities. Overall, the Focus engine is designed for regular use, and 92 octane is perfectly adequate.

As someone who frequently repairs Focus models, I recommend owners always use 92 octane unleaded gasoline. This car's engine has a moderate compression ratio - lower octane fuel may cause incomplete combustion, potentially leading to carbon buildup or knocking issues. The manual also states this clearly: 92 octane is the minimum requirement, while 95 octane is optional but not mandatory. Remember to regularly inspect the fuel system and never compromise by using substandard fuel. If engine failure occurs due to poor fuel quality, the repair costs will far exceed any savings from cheaper gasoline.

The Focus runs smoothly on 92-octane gasoline. While 95-octane is also acceptable, it's unnecessary to waste money. The key is to avoid mixing different octane ratings as it affects performance. The manual recommends 92-octane, so following this guidance is the right approach. Always refuel at reputable stations to minimize engine wear and ensure worry-free driving.
