9 Best Octane Boosters (To Help Your Engine Stay At Its Best)

Getting the most out of your car requires that you give it the care and attention it deserves. In some cases, this may include giving your car the best octane booster to help you motor perform at its very best.

And, there’s also the environmental impact to consider.

Using an octane booster will help you get the most out of your gasoline, meaning you won’t have to use as much gas. This is a big money saver, but it’s also an environmental saver.

Octane boosters help you get the best experience out of your car, save you money, and help to keep the environment clean!

What Is an Octane Booster?

Octane boosters raise the octane of the fuel in your tank, giving your car more power. They also generally help clean your engine as the gas processes through it, giving you an efficient ride.

Aren’t All Octane Boosters The Same?

Octane boosters use different additives to increase the octane in your tank. The four that are most common are Methylcyclopentadienyl Manganese Tricarbonyl (MMT), Ferrocene, Aromatic Alcohols, and Ethanol. Different chemical additives used in the best octane boosters have different effects on how your car runs.

Once the octane booster is added to your gasoline tank, a chemical change takes place, leaving you with fuel with a higher octane level.


This popular chemical is used in refineries around the world to help raise the octane level of fuel. It’s used because it’s an effective alternative to TEL, or tetra-ethyl lead, but it far more environmentally friendly. Lead is extremely harmful to the environment, whereas methylcyclopentadienyl manganese tricarbonyl is not, and it’s also not harmful to emission control devices. It makes the perfect active ingredient for lots of octane boosters.


This is an iron compound that is a cheaper alternative to MMT. It’s used because it’s a more environmentally friendly option than TEL, but it’s also a more affordable and economical option than MMT. While this is still used in octane boosters, it’s not used in refineries as often because most counties prohibit the use of ferrocene by refineries.

This is because the iron oxide that is formed during combustion is highly abrasive and can result in massive increases in engine wear.

Aromatic Alcohols

Aromatics like Toulon and benzine are effective in increasing the octane level of fuels, giving your engine better performance. This isn’t the most preferred active ingredient for octane levels because you generally have to use a very large amount of aromatic alcohols to produce a significant change octane levels.

It’s easier for most octane boosters to use MMT, but some still take advantage of the beneficial properties of aromatic alcohols.


Of course, ethanolis used by some race cars to help boost their octane levels. It’s a very effective method, but there are several things you should be aware of if you are using ethanol. It has a different stoichiometric ratio to petrol, which means that the car engine will run leaner than normal; using anything more than a 10% mix of ethanol requires the car be tuned for the fuel.

The car will have to run richer, which usually results in higher fuel consumption. You also have to keep in mind that ethanol absorbs water from the surrounding air. This can cause corrosion and algae in the fuel system.

Where Can I Buy the Best Octane Boosters?

You can purchase octane boosters wherever you buy auto equipment or online.
