1 Lucas Oil 10026-12 Octane Booster – Best Long Shelf Life Octane Booster

This octane booster is made by one of the most respected names in the automotive industry. If you need fluid for your car, then Lucas will make it. This is a brand with a long and established history.

Lucas Oil 10026-12 Octane Booster comes in a pack of 12, which substantially reduces the cost over a single bottle. It’s an excellent option for regular use.

Who can use it?

It can be used with any four-stroke gasoline engine. This includes cars and vehicles fitted with turbochargers and superchargers. You should note that it cannot be used with diesel engines.

The powerful formula contains enough to treat 25 gallons of fuel. This makes one bottle more than enough for most vehicles. If you have a motorbike, you can use part of the bottle and save the rest since it has a reasonably long shelf-life once opened.

What does it do?

Adding Lucas octane booster to your fuel will increase the fuel’s octane count by as much as 3.5 points. This means adding it to a 93 rated fuel will boost it to over 96.

Adding it to your fuel can help prevent knocking engine noises and increase the compression and, thereby, the performance. It can help with improving your vehicle’s economy too.

Finally, the good news is that this is a safe-to-use product that won’t damage your engine.


Lucas Oil 10026-12 Octane Booster

Our rating:4.8 out of 5 stars (4.8 / 5)

Pros

  • Good bundle deal.
  • Can be used with turbochargers and superchargers.
  • Safe for all four-stroke gasoline engines.
  • Adds up to 3.5 points to fuel rating.

Cons

  • Leaves hard to clean off residue if spilled.

2 Dyno-tab Octane Booster 12-Pack – Best Octane Booster Tablets

Not all the best octane boosters come in liquid form. Dynamo octane booster comes in tablet form. It’s not unheard of, but it’s still a little unusual. There seems something odd about putting a tablet in your gas tank. However, as strange as it might seem, the results are as impressive as any liquid-based alternative.

How to use them?

The tables come in a blister pack containing six. Each tablet can treat 16 gallons of fuel. There’s no score mark down the middle, so trying to treat tanks with smaller quantities of fuel will be difficult. If you have a motorcycle, it will be a nightmare and is therefore not a product that we’d recommend in this circumstance.

There’s no doubt that one of the more significant advantages of a tablet is that they create no mess. Additionally, they are easy to store. You’d have no problem taking these around with you, maybe in your glove compartment, and slipping one or two tablets into your gas tank after a fill-up.

They come in a twelve-pack and so contain enough to treat as much as 1,152 gallons of fuel. Now that’s a lot and makes these a highly cost-effective method of boosting your fuel.

How do the tablets work?

The tablets start to dissolve immediately but will take as long as 18 minutes before the full effect kicks in. Once they begin to work, they will reduce pinging and improve acceleration. They will increase the octane rating by ten points when a single tablet is added to five gallons of fuel.

They are safe with all engines and will not harm engines with O2 sensors and catalytic converters. Happily, they are particularly suitable if you have a vintage car or vehicle.


Dyno-tab Octane Booster 12-Pack

Our rating:4.7 out of 5 stars (4.7 / 5)

Pros

  • Mess-free.
  • Easy to store.
  • Cost-effective.
  • Safe with catalytic converters and O2 sensors.

Cons

  • Difficult to split for smaller doses.

3 Johnsen’s 4688-8-12PK Octane Booster – Best Value for the Money Octane Booster

Johnsen has been in business for close to a hundred years. They offer an extensive range of automotive fluids and have a strong reputation for innovation and an ability to adapt to changing market trends.

Like the company, Johnsen’s 4688-8-12PK Octane Booster is well proven, and even more importantly, a safe product. It can be used with all four-stroke gasoline engines without causing damage. This includes older engines and ones with turbochargers and superchargers.

Go for the 12 pack…

It comes in an easy to pour small bottle. You get a pack of twelve that offers fair value. And you get a much better deal opting for the twelve-pack rather than buying the bottles individually.

Improves and restores engine performance…

Once it’s been poured into your fuel system, it goes to work fast. It has a dual-acting formula that can help to improve and restore your engine’s performance in several ways.

You can expect to gain an improvement in horsepower and, therefore, better acceleration. Your engine will run more smoothly, with less sluggish performance and less hesitation. What’s more, the booster has a cleaning effect that can reduce engine noise and pings in older vehicles.


Johnsen’s 4688-8-12PK Octane Booster

Our rating:4.2 out of 5 stars (4.2 / 5)

Pros

  • Cleaning and fuel boosting properties.
  • Good value.
  • Works fast.
  • Promotes smoother running.

Cons

  • No exact figures on the degree of octane boost.

4 Rislone 4747-12PK Super Concentrated Octane Booster – Best Octane Booster for Capless Fuel Tank

Rislone is another company with a long and proven history in manufacturing fluids for all kinds and types of engines. If you need fluid for your car or engine, then the chances are that Rislone will make it.

Rislone 4747-12PK Super Concentrated Octane Booster comes in a small six-fluid-ounce bottle. It’s straightforward to pour, so it doesn’t create spillage or any unwanted mess. The good news is that it’s also just as easy to use on capless fuel tanks.

How far does it go?

A single bottle will treat 20 gallons of fuel. It can be added to all grades of fuel, including ethanol fuels. It’s suitable for gasoline-based fuel only, so it should not be used with diesel.

Like most octane boosters, it can be used on engines fitted with turbochargers and superchargers. Additionally, it’s safe for use if you have a catalytic converter or an O2 sensor.

The improvements you can expect include a smoother running engine together with better acceleration. Plus, it will also reduce engine noise in older or poorly maintained engines. A handy trick to have up the sleeve when taking out a vintage car or pulling out the lawnmower after its winter hibernation.

So, all good then?

Not quite. We do have a couple of moans and niggles.

The first is that there are undoubtedly less expensive alternatives. The second is that the bottle does resemble an orange drink bottle, which is not ideal if you have curious kids running around. It needs to be locked away securely along with all your other various chemicals and cleaning products.

Neither of these issues is necessarily a deal-breaker, but they are something to be aware of.


Rislone 4747-12PK Super Concentrated Octane Booster

Our rating:4.5 out of 5 stars (4.5 / 5)

Pros

  • Company reputation and history.
  • Reduces noise in older engines.
  • Increases acceleration.
  • Easy to pour and spill-free.

Cons

  • Higher price-point than alternatives.
  • Bottle strongly resembles an orange drink bottle.

5 Klotz KL-628 Octane Booster – Best Bulk Value Octane Booster

This comes in a one-gallon value pack. This means that it’s most suitable for home use. You’ll need to follow the instructions carefully to get the right concentration. Plus, you’ll also have to use a measuring container of some kind. This all makes it a little more awkward to use than a smaller bottle.

Careful…

Another issue is that it’s not the best pourer and so can be easily spilled. Given that it’s highly corrosive to paint, this could potentially be a nightmare. Even a drop of this stuff on your car could ruin the paintwork.

If you prefer smaller bottles, which most of us do, fortunately, they make those too. However, the formula is not as concentrated as a lot of other fuel boosters. Consequently, you may then find yourself having to use at least a couple of bottles.

Ok, but what happens once it’s in the fuel system…

Once it’s in your fuel, it will give an instant engine boost and improve compression. You can expect to enjoy a quieter and better performing engine. Even better, it can help to improve fuel economy too.

It can be added to all types of gasoline fuel, not diesel, and you can get as much as 10 points of octane boost from a single dose. This could potentially boost a low-grade 87 fuel to a high-performing 97 octane grade.

Clean as a whistle…

It’s safe to use on all engines and happily burns clean, and will not emit any sooty residue. Exceptions to this are that it should not be used on two-stroke engines or those that use diesel.


Klotz KL-628 Octane Booster

Our rating:4.6 out of 5 stars (4.6 / 5)

Pros

  • Helps give you a quieter running engine.
  • Improves economy and compression.
  • Large one-gallon value pack.

Cons

  • Difficult to pour container.
  • No measuring device is included.

6 Blue Magic NA30-12PK Turbo 108 Octane Boost – Best Octane Booster for Off-Road Vehicles

Blue Magic comes in an easy pour 16oz bottle. It comes in a pack of 12 . Price wise it’s one of the more expensive on our list. So, if you’re hunting for a bargain, this won’t be it.

Why buy it then?

Positives include the fact that it’s easy to pour, and you are therefore unlikely to get any on the floor or your paintwork. Just as well since it’s highly corrosive and will quickly strip paint.

Other positives are that you can use it in all gasoline engines, and it won’t damage catalytic converters or O2 sensors. Additionally, it’s safe to use if you have a turbocharger or a supercharger.

Blue Magic claims an increase of seven points in the octane of your fuel. You can also expect to experience better acceleration, smoother running, and better fuel economy. The potential gains for smoother running are likely to be more significant in older vehicles.

Sounds perfect…

Well, not really.

The biggest issue we have is that there are no instructions about how much to add to a tank full of fuel. You’re left guessing as to what is appropriate for how much fuel your tank can hold. We, therefore, conclude that their claims of improving your octane rating by seven points are meaningless.

If you need to find out the right concentration, you’ll have to contact customer services.

Just as frustratingly…

It’s a product that they only recommend for off-road and racing vehicles. There’s no indication why this is the case and why they don’t recommend it for use in cars used for normal daily driving.

The lack of information on both counts leaves it at the bottom of our list.


Blue Magic NA30-12PK Turbo 108 Octane Boost

Our rating:4.6 out of 5 stars (4.6 / 5)

Pros

  • Easy pour bottles.
  • Improves acceleration.
  • Smoother running engine.
  • Safe for all gasoline engines.

Cons

  • Only recommended for off-road and race vehicles.
  • No directions for the quantity required.

7 STP 78574 5.25 Oz Octane Booster Pack of 12 – Best Child Proof Octane Booster Bottle

STP is another giant in the world of fluids that are destined for your car. They have a long association with motorsport and a solid reputation for manufacturing reliable and strong performing products.

STP 78574 5.25 Oz Octane Booster comes in a tiny 5.25oz bottle, which makes it one of the most concentrated formulas on the market. The main advantage of this is that it makes storing a larger quantity just that little bit easier.

Once again, take care…

Like a lot of octane boosters, the bottle does have a resemblance to a soft drink bottle. To make sure it can’t get into the hands of an inquisitive child, it has a childproof locking cap. This is effective in preventing young children from opening the cap. However, it’s a little too effective and can leave adults struggling at the pumps too.

Ultimately, we’re sure you’ll agree it’s better to err on the side of caution with these things, but never the less it can be a little frustrating.

However…

Once you finally get the cap off and pour it into your tank, it will boost the octane count by approximately three to four points when added to 15 gallons of fuel.

Who is this for?

It can be used with all gasoline engines though it should not be mixed with diesel. It’s safe to use on old and new engines alike. It’s also safe to use on race engines with turbochargers or superchargers.

Along with boosting octane values, it will improve compression and subsequently reduce pinging and knocking. This all means a quieter and smoother running engine. You will also get to enjoy better performance and fuel economy.


STP 78574 5.25 Oz Octane Booster Pack of 12

Our rating:4.6 out of 5 stars (4.6 / 5)

Pros

  • Small bottles.
  • Childproof caps.
  • Reduces engine noise.
  • Improves performance.

Cons

  • Can be difficult to open the bottles.

Best Octane Boosters Buying Guide

Best Octane Boosters Buying Guide

Octane Boost Level

All octane boosters will increase the octane content of your fuel. The number of points that will actually be added varies quite considerably between various products. One thing to also be aware of is that all of the octane boosters come in different concentrations.

This is why we want to reiterate…

Whatever octane booster you use, you should pay very close attention to the instructions to ensure you add the right amount. Also, make sure that the booster has clear instructions in the first place.

Most octane boosters will advertise levels of a boost of around three to four points. However, by simply adding more, you can quickly increase this figure.

Engine Compatibility

Octane boosters should only be used with gasoline engines. They should never be used with diesel-powered vehicles. Other than that, most octane boosters are compatible with just about every type of gasoline engine you can think of.

You can use octane boosters in gasoline engines of SUVs, RVs, trucks, ATVs, and even your boats or lawnmowers. For those of you with performance vehicles, you’re covered here also. They are generally safe to use with turbochargers and superchargers. The best news is that they are also acceptable to use with an engine that has a catalytic converter and oxygen sensor.

Like anything you put into your vehicle, it’s always prudent to check before you buy.

Performance Benefits

The octane boost increases compression and increases your engine’s horsepower. This, in turn, improves and smooths your acceleration. The higher octane concentration also increases the efficiency of your engine and can improve its economy.

Other benefits include reducing engine noise and knocking. This is caused by the wrong fuel and air mix at pre-ignition. Using a booster helps your car run more smoothly and limit engine noise and limit the damage that can be a consequence.

Last but definitely not least…

One final benefit is the ability to eliminate some of the carbon deposits that build-up, over time, in your engine. Eliminating these deposits will reduce emissions, which is good for you, come test time, and good for the environment too.

All cars can benefit from using an octane booster. However, older and poorly maintained vehicles have the most to gain. Also, cars that have been standing for a long time can particularly benefit.

Packaging

The most important consideration for us is if it can be safely added to your fuel tank with zero chance of spillage. In liquid form, this stuff is highly corrosive, and even a small amount will damage your paintwork. You should always look for a booster with an easy pour bottle, like the Blue Magic NA30-12PK Turbo 108 Octane Boost or the Rislone 4747-12PK Super Concentrated Octane Booster.

The best option for zero mess?

To guarantee no chance of spillage, the Dyno-tab Octane Booster Tablets win hands down. They are the easiest to add to your tank, and since they are in tablet form, they can never damage your paintwork.

A lot of octane boosters look strikingly similar to energy or soft drinks. High levels of caution should therefore be used when storing them if there are children in the house. In this instance, STP 78574 5.25 Oz Octane Booster has the best childproof cap though it can be a little tricky for us adults to open too!
