Are you one of those car owners who are so careful with your car that you do everything to protect it from possible (sometimes imaginary) damage? Are you one of those car owners who are very strict on oil change interval that you’d rather change oil earlier than later? Are you one of those individuals who opt to go for premium fuel even if it’s not required in your vehicle just to protect your engine from possible damage caused by pre-ignition?
I have news for you: you might be going over the top, especially with the use of premium fuel. The fact is, premium fuel isn’t a must. In fact, even those cars that are said to require premium fuel can still use the regular kind. All you really have to watch out for when using regular fuel is the possible occurrence of pre-ignition or knocking. This incident can be best described as “self-explosion”, meaning the explosion of the mixture inside the engine even before it is ignited by the spark plugs. This can happen with the use of regular fuel—in some cases.
However, that’s easy now because most cars already have a knock sensor, which can adjust the engine when it detects knocking. Also, the first occurrence of pre-ignition does not automatically spell engine damage. And, when knocking occurs upon your use of a particular grade of fuel, you can easily climb to the next grade and see if the knocking disappears.
There’s also this misconception about premium fuel having the ability to clean the engine, but that’s not really true. Yes, they may have a little amount of cleaner, but it won’t actually make any difference.
So, if you have the tendency to choose premium fuel over the regular kind, even if it’s not even required for your vehicle, you must know that you’re only wasting money.
