Maintaining a healthy motor is all about proper maintenance. If you do your part, change your oil, filters, and other fluids, your car will reciprocate through long-term reliability. However, sometimes you can do more to take care of your car beyond regular maintenance. Let’s talk about Motul additives, what they’re for and how you can use them to keep your car in the best shape possible!

What are Motul Additives?
Motul is one of the several companies that has invested serious effort into researching advanced methods of engine cleaning that go beyond what engine lubricants can achieve.
We’re talking areas around piston rings, hydraulic lifters and other hard to reach spots. However, even if engine lubricants were capable of this additional cleaning, in many instances it’s the fuel system or the transmission that needs a good scrubbing, which are a completely separate worlds of their own.
Since tearing the engine apart every time you want to clean these critical components is impractical, we’ve devised a line of additives that can be added to engine oil, fuel, or elsewhere to get the job done.
These additives are custom-tailored to provide cleaning, lubrication, and performance boost depending on which product you’re using.
How do Motul Additives Work?
We’ve designed our line of additives to be as surgical as possible in terms of their effect. Each product in this lineup has a mission of its own, whether it’s to clean your hydraulic lifters, clean your valves, or even clean your radiator.
Our additives achieve these results by adding certain compounds to your fuel, oil or coolant, and then using these fluids as a catalyst to reach deposit buildups, no matter where they are.
When you use Motul additives, you’re not adding a potentially damaging substance to your oil/fuel/coolant. On the contrary. Once our additives do their job, they will blend into the surrounding lubricant/fuel.
Are Oil/Fuel Additives Effective?
Right off the bat, the answer is yes. Our fuel and oil additives are effective when used when following the manufacturer’s instructions. The stigma surrounding additives stems from brands that overestimate their products’ abilities, which often leads to disappointment.
We don’t have to overestimate anything. Our additives are highly effective which is why we can safely say that your car will benefit from them if you decide to use them. Of course
Motul Additives — The Complete Lineup
Our additives are divided into four groups:
- Gasoline additives
- Engine oil system additives
- Diesel additives
- Transmission, cooling, and throttle body additives
Gasoline Additives

Fuel covers a lot of distance by the time it reaches your engine. It passes through one or more fuel pumps, a variety of fuel lines, and other components until it finally reaches your intake valves.
Since it travels at relatively high pressure, fuel is a good vessel for additives to use. As it turns out, your engine builds up all kinds of oxidation and other deposits inside the fuel system. Some of this buildup is a result of poor fuel quality, while some deposits are normal depending on the design of your engine.
We’ve developed our Fuel System Clean additive to give your fuel a strong cleaning power, which disperses water condensation and removes any residues from your fuel system.
On the other hand, our Valve & Injector Clean is also added to the fuel, but its job is slightly different. By cleaning valves and fuel injectors, this additive helps improve your fuel efficiency while restoring optimal fuel flow.
Engine Oil System Additives

Despite the efficiency of cutting-edge engine lubricants such as our 8100 series, you’ll sometimes find a buildup of deposits and contaminants in various parts of the engine.
Our Engine Clean is a custom-tailored formula whose main job is to get rid of these deposits and ensure that your engine is running as smoothly as possible. This additive cleans residue from piston grooves and acts to further reduce friction between the piston rings and cylinder walls. Overall, the result is more efficient combustion and hence a better running engine.
The Hydraulic Lifter Care additive thoroughly cleans valves, valve guides and is capable of reducing or eliminating valve train noise. Both of these products can be used in any type of gasoline or diesel engine. Speaking of diesel…
Diesel Additives

Our diesel-based additives come in two forms — Diesel System Clean and DPF Clean. Both of these are designed specifically to cater to the needs of modern diesel engines.
Diesel System Clean works by eliminating unwanted contaminants from your vehicle’s fuel system, but also the fuel itself. This is a great choice for diesel owners who want to extend the life of their injectors and other high-pressure fuel system components in their car or truck.
The DPF Clean works by reducing the overall amount of soot that is reaching your DPF. By doing so, it makes regeneration cycles easier on the car, while also improving the efficiency of this process.
Transmission/Cooling/Throttle Body Additives

Lastly, we have the Automatic Transmission Clean, Radiator Clean, and Throttle Body Clean, which form a little group of their own.
Automatic Transmission Clean is an additive designed to be added to AT fluid. It works in all types of automatic gearboxes, including modern CVT and DCT systems. As it circulates through the transmission, this additive removes various deposits as well as any contaminants that end up in the AT fluid.
Radiator Clean is a product designed to clean the often sensitive cooling system internals. It is a non-aggressive cleaner that will remove oxidation and scaling from both metallic and plastic parts of your cooling system.
Last but not least, we have the Throttle Body Clean. This is a standard throttle body cleaner product that we’ve tweaked to be extra effective in removing carbon buildup and other deposits from your car’s intake system.
Give Your Car a Proper Flush with Motul Additives
Running an additive through your car could potentially do wonders for your engine. This is even more likely if your car has a decent number of miles on the odometer. We highly recommend our Motul additives for any engine as we believe in our formulas and their effectiveness. Chances are you will too when you give them a try!
