Using two different types of gas in your vehicle typically doesn't cause immediate damage, but it can lead to engine inefficiency over time. For instance, mixing regular and premium gasoline could slightly alter the fuel's overall octane rating. Vehicles requiring premium gas might experience reduced performance and fuel efficiency when lower octane fuel is used. To maintain optimal engine health and performance, it's advisable to stick with the fuel type recommended by the vehicle's manufacturer.
