Octane Boosters simply raise the RON (Research Octane Number) of the fuel.


A conventional petrol engine relies on its ability to compress an air/fuel mixture inside the combustion chamber, to be ignited by the spark plugs at a very precise moment. Basic physics will tell you that the compression of the air/fuel mixture creates heat as the molecules speed up and kinetic energy becomes heat energy. The problem with this is if enough heat is created, it can cause the mixture to self-ignite. This is referred to as Pre-Ignition or “Pinging” in reference to the sound it makes. This is incredibly detrimental to an engine and is one of the quickest ways to shorten your engines life.


A cars potential for power output boils down simply to how much air it can compress into the smallest space possible. The measurement of this is referred to as a “compression ratio”. As the mixture is compressed more and more, the heat energy produced will increase exponentially, as does the potential for Pre-ignition.


The RON rating is a measurement of a fuels resistance to ignition. A 98RON fuel is less volatile than a 95RON fuel, and is harder to ignite. This makes it more ideal for performance focused or turbocharged engines that have high compression ratios or use a turbocharger to operate above 100% volumetric efficiency.


On the other hand, using a high RON fuel in a car that does not require it, means it wont burn the less Volatile fuel as completely and you will suffer poor economy and power.


An Octane Booster when added to a fuel, increases its RON. If you can hear a light inconsistent rapping or knocking from your engine when accelerating or under load, it may be due to the incorrect fuel being used and we would recommend Octane Booster as a quick remedy.


Will Octane Booster make my Car Faster?


A common misconception is that using an Octane Booster will make your car quicker. The simple answer is no, it will not. The only circumstance in which it will help your car go faster is if fuel with an inadequate RON was used in the first place.

What is a Manual Transmission and Differential?

Manual Transmissions and Differentials are deceptively simple devices. A Manual Transmission in its simplest of forms, drives the reciprocating motion created by engine through a pair of gears. You change these gears to different sized gears to effect the speed at which the output spins. A Differential transfers the motion from one axis to another through a series of meshed gears. An exaggerated example of this is shown below:


Transmission and Differential


The above gears are often referred to as an under-drive. The small pulley is turning the large pulley, this is akin to a vehicles first gear, where the engine rpm increases quickly but the cars speed does not. This allows for mechanical advantage, giving higher drive force at the expense of speed. If both gears were the same size, the effort and drive speed would be identical, allowing for a higher vehicle spee, as the engine is going to reach its maximum rpm at a slower rate. This is similar to a third or fourth gear.


If the driver gear was larger than the driven gear, it allows the engine to turn slowly, with a comparable road speed (similar to a fifth or sixth gear). This is also the reason your final gear is typically referred to as “overdrive”.


How Additives assist your Transmission and Differential


As you can imagine, there is a lot of force placed on the teeth of your vehicles gears and manufacturers recommend particular gear oils to lubricate them. This will also help reduce wear, noise and help in obtaining a smooth shift. A gearbox with no oil in it will only last a matter of hours if you’re lucky.


Gear additives are available to add additional protection, and make for a smoother shift. The way they do this is simple on the surface…

Take for example Nulon’s G70 additive, one of the most popular additives on the market. It contains polytetrafluoroethylene (PTFE) which on a molecular level is very very small. When placed under pressure it actually penetrates the metal surfaces. While the metal components may appear smooth at first, when viewed up close the flat machined surfaces actually appear like the surface of the moon, with rises and undulations. The additive embeds itself in the metal, providing an additional layer of protection, and smoothing the inconsistencies in this surface. This makes for a smooth shift, quiet operation and additional protection.
