Although this is one of the most common car myths, it has got no basis! Premium Fuel is more expensive, but that doesn’t mean it’s purer or cleaner than the regular fuel that you fill up with. Premium Fuel is used for particular cars that need low combustion fuel, but it won’t make any difference to your normal vehicle. You will get to know if your vehicle requires premium fuel by reading your owner’s manual. If your car’s engine requires a higher-octane level then you should use premium. If not, don’t waste your money!
