We deliver to mainland France (excluding overseas territories and Corsica) and Belgium. You can choose delivery to the address of your choice (home, office, etc.) or to a relay point. Shipping costs are free for all orders of at least €45.
Overdosing an additive will not change the effectiveness of the product, we recommend that you respect the doses and instructions for use recommended for each of our products.
It is recommended that additives be used independently to maximize the effectiveness of each. Unless the additive's specific instructions for use indicate that they can be used together, it is best to apply each additive separately, with an interval between uses. This approach ensures that each additive can provide its full benefits without interference from the other.
You cannot use additives in your engine oil with the following engines: (EB) 1.2 PURETECH and (EP) 1.4 and 1.6 THP from PSA. These engines have the particularity of having the timing belt that passes through the engine oil, therefore PSA prohibits the addition of any additive in the oil of these engines mentioned above.
We cannot guarantee the full effectiveness of a product whose DLU has been exceeded, because its technical qualities may have been altered.
You should refer to your manufacturer's manual, or you can also find information about the lubricants to use for your vehicle on this page: https://www.bardahloils.com/fr
Injector Cleaner is suitable for this purpose.
There are several causes: either the air intake or the injection system are closed, or the tank is contaminated. Diesel injection cleaner improves acceleration.
Please note: without diagnosing your vehicle we cannot guarantee anything. Therefore, a visit to an Eco engine cleaning partner would be preferable to get an answer to your question.

Unfortunately, there is no solution to improve your fuel. But you can use Injection Cleaner after siphoning your tank.
No, you must use both products separately and both after refueling.
The product is, in fact, compatible with all engines. It is important to respect the recommended dosages.
This product is suitable for classic mineral oils.
This product is compatible with all types of oils.

Both products have different additive packages: - Injector cleaner (1155): will clean and reduce combustion chamber deposits. - 5 in 1 degreaser (9365): will clean and reduce combustion chamber deposits, but also help clean and regenerate the DPF by forming soot that burns at a lower temperature.
It also has a cetane improver which will help with cold starting.
The optimal use of the 5-in-1 Diesel Cleaner mainly depends on your driving habits and the distances traveled. To ensure the proper functioning and performance of your vehicle, we recommend applying the treatment twice a year or every 5,000 km if your trips are mostly short urban journeys. These conditions put more strain on the engine without allowing it to reach an optimal temperature, which can lead to the buildup of residues. For those who do longer trips, allowing the engine to run at an optimal temperature over an extended period, applying the 5-in-1 Diesel Decarbonizer twice a year or every 10,000 km is sufficient to maintain maximum efficiency and protect the engine from harmful deposit buildup. These recommendations are designed to tailor the treatment to your specific needs, ensuring optimal protection and performance of your engine in the long run.
The product must be used in 60L of fuel.

It is recommended to first use the No smoke product (ref. 1020), then the Diesel injection cleaner (ref. 1155).
The quantity to be injected depends on the number of cylinders: 4 cylinders = 250ml / 6 cylinders = 375ml / 8 cylinders = 500ml. This product must be added hot to new oil. It is advisable to drive a few km after adding the product. We also advise you to obtain a technical inspection pack, ref. 90453 (stop smoke + injector cleaner).

Yes, this treatment is compatible with all vehicles equipped with an SCR system using AdBlue.
The optimal use of the Essence 5 in 1 degreaser depends mainly on your driving habits and the distances traveled. To ensure the proper functioning and maintenance of the performance of your vehicle, we recommend applying the treatment twice a year or every 5,000 km if your journeys are mainly short trips in urban areas.
These conditions put more strain on the engine without allowing it to reach optimum temperature, which can promote the build-up of residue.
For those who undertake longer journeys, allowing the engine to operate at optimum temperature for an extended period, applying 5 in 1 Petrol Cleaner twice a year or every 10,000 km is sufficient to maintain maximum efficiency and protect the engine from the build-up of harmful deposits.
These recommendations aim to tailor the treatment to your specific needs, thus ensuring optimal protection and performance of your engine over the long term.
The product must be used in 60L of fuel.
This product is not compatible with two-stroke engines, we recommend using our 5 in 1 Petrol Cleaner (reference 1325) instead.
For a motorcycle, it is recommended to put half the bottle when going to the pump and add 10L of fuel (for a car; put the whole bottle).
It is advisable to drive until exhaustion with sharp acceleration when the engine is warm. If the carburetor is very dirty, the aerosol air circuit cleaner can be used when the carburetor is disassembled.

Yes, except for vehicles equipped with a catalytic converter and engines running on biofuel type E85.
The product contains potassium. The optimal treatment is 10L of fuel for 10ml of product. Please note that the lead alkyls previously used have been replaced by additives containing alkali metals (sodium, potassium, etc.) because the lead alkyls were polluting and harmful to the exhaust pipes of recent vehicles.
The Essence treatment, ref. 1069, manages maximum 80L of fuel and lubricates the cylinders for example. 10 ml of the other, with ref. 1149, manages 10L of fuel. This product is concentrated and reduces fuel consumption.
This product is indeed suitable for all types of engines.
No, because the two products have different characteristics: the first is intended for pollution prevention and protection of the injection system and the second for cleaning.

When to use: Oil Booster 2023 should be added to the engine oil at every oil change. It is a key element to maintain good engine lubrication over the long term, especially for vehicles running on E85.
Product Benefits: This product is specifically designed to improve the performance of engine oils that are not originally designed to withstand the effects of E85. Unburned E85 can mix with the engine oil, reducing its effectiveness. 2023 Oil Booster compensates for this risk by enhancing the properties of the oil.
Additional properties: In addition to improving the oil's resistance to E85, this product also has anti-wear properties and is hyper-lubricating. This contributes to better protection and longer engine life.
Frequency of use: It is recommended to use Superethanol 1371 treatment at each tank of fuel, or at least every other tank. This regularity is essential to maintain the benefits of the product.
Product Purpose and Benefits: Super Ethanol 1371 treatment is designed to offset the drying effect of E85 throughout the fuel system and up to the top of the engine. E85, due to its high ethanol content, can cause some dryness in the fuel system. Super Ethanol 1371 treatment acts as a lubricant for these parts, reducing the risk of damage or premature wear. In addition, this product has water dispersing properties, which helps maintain the efficiency and cleanliness of the fuel system.
After installing the E85 conversion box: E85, being more "stripping" than SP95 or SP98, can cause microparticles to detach in the tank, risking fouling the injectors. It is therefore recommended to use the injector cleaner 1301 immediately after installing the box.
It is recommended to use the cleaner once or twice a year. If your vehicle is used a lot, prefer two uses, ideally during the summer/winter E85 season change. This recommendation is due to the variation in the composition of E85, which contains approximately 85% ethanol in summer and 65% in winter (with a greater proportion of SP98 in winter to facilitate cold starting).
When using the injector cleaner, it is not necessary to add the "Superethanol treatment" to the fuel. Although there is no incompatibility, this combination is unnecessary because the injector cleaner already fulfills the role of the Superethanol treatment.
