Does the type of gas I put in my car postpone or prevent service?

The answer is no. Most modern cars are designed to run on economy grade fuel. If you pick high-octane fuel at the gas station, you’re only draining money from your wallet. In general, high-octane fuel doesn’t contain any added benefits and it’s unnecessary.

What does high-octane fuel do? Many drivers who own sports cars or luxury vehicles report that fuel with a higher octane increases their car’s performance. However, this increase in capability is attributed to the additives in high-octane fuel, not the fuel itself.

The main purpose of fuel with higher octane is to prevent the knocking or pinging sound sometimes heard in an engine. The knocking sound is a result of an occasional and sudden ignition in an automobile engine, a mishap that can damage a vehicle.
