Best Octane Boosters and Additives of 2021


If you own an automobile that runs on the standard spark-ignition internal combustion engine, you might have come across the term ‘knocking’ at some point. Knocking is the explosion caused by the premature burning of fuel in the combustion chamber. Your fuel’s octane number determines its combustion quality. Higher the octane number, higher is its resistance to premature combustion and ‘knocking’.

Octane boosters are additives that can be added to fuel to kick up its octane number. A good quality octane booster can significantly enhance your vehicle’s performance. In this article, let us take a look at the benefits of 7 high-quality octane boosters available in the market today.
