Modern car maintenance is no longer limited to oil changes, filter replacements and servicing Modern vehicles have complicated parts that require special attention.
In this context, additives play a strategic role: they optimise performance, reduce wear and tear, and extend the service life of the engine and its peripheral components. Used regularly, they help prevent clogging issues before they become costly to repair. They also offer a simple and accessible solution for keeping the engine in optimal condition, even between services.
Discover the five essential additives to ensure comprehensive and effective maintenance of your car.
Diesel power 7 : a comprehensive treatment for carbon build-up
By its very nature, a diesel engine generates more soot and carbon deposits than a petrol engine. Over time, these contaminants accumulate in critical components such as the injectors, combustion chamber, fuel system, turbocharger, EGR valve and particulate filter, negatively affecting performance, efficiency and emissions.
Wynn’s Diesel Power 7 is the most complete diesel additive, specifically developed to address all of these issues in just one tank of fuel. Acting in seven key ways, it delivers fast, visible and long‑lasting results.
Wynn’s Diesel Power 7 cleans and revitalises diesel engines by removing carbon and soot from the combustion chamber, EGR valve, turbocharger, and exhaust system, helping to restore power, improve fuel efficiency, and ensure smoother running. It supports both active and passive DPF regeneration to reduce backpressure, lower emissions, and cut smoke. With its combined cleaning, lubricating, and protective action, it helps return engines to optimal performance while extending the life of key engine and fuel system components in one simple treatment.
Hybrid Cleaner & Protector: a high-tech additive designed specifically for hybrid engines
Hybrid vehicles, which are often used in urban environments, are subjected to frequent start-stop cycles that can lead to the fuel system becoming clogged. In this specific context, the Hybrid Cleaner & Protector has been specially developed to maintain the performance of petrol hybrid engines whilst cleaning and protecting key components of the fuel system.
As soon as it is added to the fuel tank, the additive acts on the injection system by removing deposits that could impair spray quality. The engine thus runs more smoothly, particularly during transitions between electric and combustion power.
One of the key benefits of this treatment lies in its ability to reduce the risk of LSPI (Low Speed Pre-Ignition), a phenomenon that can cause dangerous knocking and premature damage to direct-injection engines. By limiting these pre-ignitions at low revs, the additive not only helps to protect the engine but also optimises its performance during low-speed driving, typical of urban journeys.
Thanks to its protective effect on the entire fuel system, this additive reduces internal friction and helps extend the service life of components. A solution particularly suited to the specific demands faced by modern hybrid vehicles.
Ceramic Engine Protection: long-lasting protection against wear
Over time, internal engine friction causes natural mechanical wear that can impair performance and increase fuel consumption.
Wynn's Ceramic Engine Protector provides a protective ceramic coating designed to reduce this friction over the long term. Its ceramic technology forms a durable film capable of withstanding the high temperatures and internal pressures within the engine.
This protection is particularly beneficial for critical components such as hydraulic tappets, bearings and the turbocharger. By reducing metal-to-metal contact, it minimises mechanical noise and extends the service life of internal parts. The engine also becomes more responsive and runs more smoothly, whilst consuming less fuel thanks to reduced friction losses.
This additive is particularly recommended for engines that have already clocked up a certain number of miles, but also for drivers wishing to maximise the longevity of their engine.
Ad Protect: prevents AdBlue® from crystallising and protects the SCR
Modern diesel vehicles equipped with the SCR system rely on the high quality and stability of AdBlue®.
However, this fluid can crystallise, particularly in the event of evaporation or temperature fluctuations, leading to blockages, malfunctions, and error messages. Ad Protect has been specially formulated to prevent these issues and preserve the integrity of the SCR (Selective Catalytic Reduction) system.
By stabilising the fluid and limiting the formation of deposits, it ensures correct spraying and optimal operation of the SCR catalyst. This results in a reduced risk of breakdowns, downtime and particularly costly repairs, particularly to the AdBlue® pump, the SCR injectors or the catalyst itself.
Regular use of Ad Protect therefore helps to extend the service life of components and maintain emission control performance in line with environmental standards.
Special Diesel MOT: reducing emissions before the test
Over the years, MOT standards have become significantly stricter with regard to emissions from diesel and petrol engines.
Wynn's Pre-Emission Test Treatment has been formulated to effectively prepare a vehicle for this test by acting on the entire fuel system, from the fuel tank to the exhaust.
It removes deposits from the fuel system and reduces emissions at the source. By cleaning the system, it also helps reduce fuel consumption caused by build-up. After treatment, the engine runs more smoothly, smoke emissions are reduced, and the risk of failing the MOT test is significantly lowered.
And the good news ? This product comes with a money-back guarantee and also exists for petrol engines!
Conclusion: Additives that are essential for performance and longevity
Using the right additives helps maintain a vehicle well beyond routine mechanical servicing.
Choosing these additives means investing in the vehicle's longevity, reducing maintenance costs and enjoying a healthier, more efficient and more economical engine.
