The type of gas that will last more miles depends on the fuel efficiency of the vehicle. Generally speaking, gasoline with a higher octane rating offers more miles per gallon (mpg) and better performance. For instance, premium gasoline (91-94 octane) typically provides better mileage than regular gasoline (87 octane). The reason is that higher-octane gasoline has a slower burn rate, allowing the engine to extract more energy from the fuel.
However, it's worth noting that the mpg advantage of higher-octane gas is often minimal and may not be significant enough to justify the higher price. Additionally, newer vehicles with modern engine technologies might not require premium gas and can run efficiently on regular gasoline. Consult your vehicle's owner's manual to determine the recommended fuel type and octane rating.
