Should the Kia KX5 use 92 or 95 octane gasoline?

Turbine-powered vehicles are best suited for 95 octane gasoline, but the actual choice should be based on the engine's recommended gasoline rating, which is indicated in the user manual and on the fuel tank cap. Below is an introduction to gasoline: 1. Gasoline: Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled and cracked from petroleum, used as fuel. 2. Physical and chemical properties: At room temperature, gasoline is a mobile liquid ranging from colorless to light yellow, difficult to dissolve in water, flammable, with a distillation range of 30°C to 205°C. It explodes upon contact with fire when the air concentration is between 74 to 123 grams per cubic meter. The calorific value of gasoline is approximately 44,000 kJ/kg (the calorific value of fuel refers to the amount of heat produced after 1kg of fuel is completely burned).
My Kia KX5 manual clearly states that 92-octane gasoline can be used, but I always fill up with 95-octane because the higher octane rating prevents engine knocking and protects internal components. The 95-octane fuel provides quicker throttle response during acceleration and smoother power delivery, which suits the KX5's turbocharged engine design. Although 92-octane is cheaper, 95-octane offers slightly better fuel efficiency and helps reduce carbon buildup over time. I always choose reputable gas stations to avoid substandard fuel. If you're unsure, consulting the manual is the most reliable approach. Remember, high-octane fuel is safer under heavy load conditions. Considering the cost, 95-octane is more expensive but worth the investment for your car's long-term health.
