Should the Lincoln MKC use 92 or 95 octane gasoline?

[DiHailey]

Lincoln MKC's manufacturer specifies the minimum fuel grade as 92 octane. The following are details about the 2019 Lincoln MKC: 1. Body dimensions: The length, width, and height of the body are 4552mm, 1864mm, and 1657mm respectively, with a wheelbase of 2690mm. 2. Powertrain: The Lincoln MKC is equipped with a 2.0T-EcoBoost engine and a 2.3T-EcoBoost engine. The 2.0T engine has a maximum power of 186kW (253PS), and the transmission system is matched with a 6-speed automatic transmission.

I've been driving the Lincoln MKC for over half a year after switching to it, mainly using 95-octane gasoline. This car has a high-compression turbocharged engine, and using 92-octane can easily cause annoying knocking sounds in the engine, which can damage the engine and increase fuel consumption in the long run. I remember the manual clearly recommends 95-octane, so don't risk it just to save a little money. Once on a long trip, the gas station only had 92-octane, and while it was okay for one-time use, the acceleration was noticeably weaker. I switched back to 95 as soon as I got back, and the throttle response improved significantly. After all, the MKC is a luxury SUV, and repair parts are extremely expensive. Rather than saving on fuel costs, it's better to prioritize safety. Even though gas prices have risen, I still insist on filling up with 95-octane at reputable gas stations to avoid poor-quality gasoline damaging the car. In daily driving, especially when overtaking on the highway, 95-octane ensures more stable power output and smoother cold starts. In short, following the manual is always the right choice.

Let's talk about refueling the Lincoln MKC. From an economic perspective, I firmly believe 95-octane gasoline is absolutely more cost-effective. Sure, 95-octane costs more per liter, but prolonged use of 92-octane significantly increases engine knocking risks. A single repair for spark plugs or pistons could cost hundreds or even thousands—wiping out any fuel savings while damaging your vehicle. Based on my experience, using 95-octane actually improves fuel efficiency, saving about half a liter on average. The manual recommends 95-octane for good reason: Lincoln engines are precision machines. While the ECU can adjust to lower-octane fuel, the risks outweigh the benefits. With current high fuel prices, I understand the urge to save, but consider MKC's premium price tag—don't penny-pinch at the cost of major damage. Plus, in major cities, 95-octane offers more reliable quality, reducing carbon buildup and extending maintenance intervals. Protecting your Lincoln with 95-octane ensures safer driving and greater peace of mind.

The Lincoln MKC's engine design is better suited for 95-octane gasoline, as the higher octane rating helps prevent knocking and avoids abnormal combustion that could damage engine components. While using 92-octane may be cheaper, it could lead to reduced power and increased fuel consumption. It is recommended to follow the manual and use 95-octane to ensure optimal performance and engine protection. In remote areas where 95-octane is unavailable, occasionally using 92-octane is acceptable, but long-term use should be avoided. Choosing gasoline from reputable gas stations ensures more stable fuel quality.
