What is octane?

Octane is simply a measure of how much heat and compression the fuel in your vehicle can withstand. At high pressures, fuel can pre-ignite, meaning burn, or explode causing engine damage. This reduces your engine’s efficiency and performance, and can lead to increased emissions from your exhaust system.

When air and fuel are ignited by your spark plugs, in any internal combustion engine, a portion of that compressed air-fuel powers your vehicle and the rest is filtered through the exhaust system. Octane determines how well the fuel in your vehicle will respond to this process. You need to have the right octane level to give your engine maximum power with minimum emissions.

What else should you know about the 87, 89, and 93 octane rating

Buy in higher octane fuel is not guaranteed to improve your vehicle’s performance and may not increase your overall fuel economy. Higher octane fuels contain additives that make it more costly to produce, therefore you pay more for it at the pump. Since there’s no labeling on the pump to tell you what gas additives are being used, you really don’t know if you’re putting the right stuff in your car to get the results you need.

One way to control the results is to use a commercial octane booster. 

What is an octane booster?

Check out this  video that shows how octane works in the fuel tank.

Octane booster is a fuel additive that’s designed to help your engine run better and last longer. Added directly to your gas tank, it helps to mitigate problems caused by low quality, low octane gasoline.

How do octane boosters work to enhance your car’s performance?

Octane boosters give fuel more stability under compression by ensuring that fuel in your cylinders ignites at the exact moment it should.

When should you use an octane booster?

If your engine is knocking, try adding an octane booster to your gas tank right away. Generally, you’ll add octane booster with every fill-up to maintain performance. Some people only use octane booster during winter, while others use it year-round. How can you find the best fuel octane booster for your fuel tank?
