Higher Octane Usually Provides ZERO Benefit (Reply to this comment)
by thanva
According to the United States Federal Trade Commission, which regulates fair trade and deceptive advertising practices:
...in most cases, using a higher octane gasoline than your owner’s manual recommends offers absolutely no benefit. It won’t make your car perform better, go faster, get better mileage or run cleaner. Your best bet: listen to your owner’s manual.
The only time you might need to switch to a higher octane level is if your car engine knocks when you use the recommended fuel. This happens to a small percentage of cars. If it doesn’t knock when you use the recommended octane, you’re using the right grade of gasoline
As a rule, high octane gasoline does not outperform regular octane in preventing engine deposits from forming, in removing them, or in cleaning your car’s engine.
