An effective and efficient fuel additive, this is basically a race fuel concentrate booster with formulations that will make your premium fuel becomes loaded with so much octane.
With few minutes drive of your high-performance car, you will feel a great difference in terms of its overall performance.
What are Octane Boosters?
Octane boosters basically add up to octane content of the fuel. If your available fuel is rated with, say, 87 octane rating but your car requires a minimum of 91 to make it perform to its utmost performance, then you need an octane booster that promises to add 3 times the extra boost you need for your fuel.
If you want your racing car to have move power with its engine, octane boosters can maximize its horsepower by adding more octane to the fuel.
Technically speaking, octane boosters can also help by smoothing out the internal combustion process so that your engine’s pistons can have stabilized pumping actions.
It can also prevent high compression engines from knocking and can clean out carbon deposits on the engine parts.
Octane literally is a colorless hydrocarbon of the alkaline series that is highly flammable and produced during the process of refining petroleum.
But when it comes to internal combustion that occurs on engines, octane becomes the measurement of the fuel compression resistance which we call octane rating.
Gasoline today are rated by octane rating though countries follow different ratings. In the US, there are the 87 (regular), 89 (mid-grade), 91 (premium) and 93 (super premium) up to 97 octane ratings.
The higher the octane number, the more efficient the gas can burn in the compression chamber and the better for the engine to resist knocking or pinging.
On the contrary, the lower the rating of the fuel, the more prone the fuel can ignite without reaching the optimal compression ratio.
With less compression, this makes it difficult for the pistons to work smoothly and eventually without the right timing this would send shockwaves throughout the engine and cause knocking (ping) or pre-ignition and this is damaging to the engine block as a whole.
So does this mean that all cars including off-road vehicles should use high octane fuel? Not necessarily. Only cars with high-performance engines and capable of a high compression ratio can benefit from high octane fuel.
Pre-Purchase Considerations
Here are some considerations if you’ll be buying your octane boosters.
It must be safe for oxygen sensors – Almost all new vehicles are equipped with oxygen sensors to detect emission levels of the exhaust. If O2 gets damaged or covered with carbon, your warning signal on your engine may not work.
It must be catalytic converter friendly – These converters do their jobs by converting toxic gasses coming from the exhaust into less toxic substance.
If this gets damaged, clogged or contaminated, your car will be spewing out toxins in the air and will fail emission tests.
It must be turbo and supercharged engine compatible – If you need it for your sports cars or racing cars. These engines need higher octane in their fuels.
If you need boosters for off-road vehicles, there are octane boosters that are designed for these. Read labels first.
Wrapping Up
If your vehicle seems to be underperforming and emitting weird sounds inside its engine, you probably have carbon deposits on your system or you are using fuel that has low rated octane which is somewhat damaging to your engine’s internal parts.
If you’ll try one of these boosters on the list and all the symptoms disappear including black smokes from your carburetor, then good news, you have found the best octane booster which your car needs to have regularly.
