With regular use, combustion engines tend to accumulate residues and deposits due to the impurities present in the fuels. This condition compromises the regular atomisation of the fuel, causing the engine to lose performance and increase fuel consumption.Bardahl fuel additives restore 100% the flow of the injectors reducing fuel consumption by 5%, generating performance and economic benefits.

Which fuel additive to use?

Petrol Engines

• Top Gasoline, designed for indirect fuel systems.
• Top Gasoline Evo, designed for direct injection systems.
• Top Gasoline Repower, one-shot energetic treatment for all fuel systems.

Diesel Engines

• Top Diesel, suitable for all diesel engines.
• Diesel Injector Cleaner, shock treatment for all diesel engines.

LPG Engines

• Lpg Additive, cleaning the fuel system of LPG vehicles.

Bardahl DPF Cleaner allows the regeneration of the particulate filter and the maintenance of the correct differential pressure value inside the device. Regular use avoids clogging of the filter even in urban contexts and forced regeneration interventions by lowering the regeneration temperature and slowing the natural degradation.

METHOD OF USE
Add a 250ml bottle to a diesel tank (about 60lt).
For better mixing with diesel, it is recommended to pour the additive into the tank before filling.
Repeat every 3000 km for continuous treatment.

In some cases, the viscosity class is not set by the manufacturer or indicated in the owner’s manual. In this case, the user can choose the viscosity best suited to their engine based on the external temperature and their driving style.

The SAE viscosity class of a multi-grade oil is defined by two numbers separated by the letter “W” (stands for ‘winter’). The initial number relates to the viscosity class measurement at low temperature and the second at high temperature or 100° C. The higher the number, the greater the viscosity of the lubricant for a given class. Lubricants with a low initial number (meaning more viscosity at lower temperatures) are a better choice when vehicles are used mainly in colder climates. On the other hand, lubricants with a high second number (meaning more viscosity at higher temperatures) are a better choice when vehicles are used for sports driving or where temperatures are higher. In latest generation cars, low viscosities are also indicated to improve fuel economy.

By correctly reviewing the product specifications, you can get information on and understand the basic quality levels a lubricant meets or exceeds. However, this indication does not specifically tell you by how much a lubricant may exceed the minimum standard. Lubricants that meet the same minimum level are thus often incorrectly considered as qualitatively identical when, in fact, they are not. Some exceed standards more than others.

The oil change interval is determined by the manufacturer and is indicated by the vehicles’ on-board computer or in the owner’s manual. However, the manufacturer also generally indicates a time interval for replacing lubricants. Driving style, type and intensity of use and external environmental conditions can all affect the length of this interval. 

Absolutely yes, you can use Bardahl motor oil in any case. Make sure that the lubricant complies with the specifications and SAE viscosity classes required by the motorcycle manufacturers (shown in the use and maintenance booklet). Even with lubricants of a different brand than the recommended one, the guarantee remains valid.

No. Generally, motorcycles that have an integrated gearbox and oil-immersed clutch need specific lubricants that can lubricate the engine and transmission. This assures the efficient transfer of driving force from the engine to the gearbox without excessive slippage between the clutch discs. Regardless of this, bear in mind that motorcycle engines operate at higher speeds and temperatures than automobiles. For this reason, they require a special kind of oil which can work under and support these more stringent conditions.

On the other hand, motorcycle oil may not be suitable to or meet the specific needs of the latest generation automobiles such as those designed for long journeys, fuel economy, vehicles with low saps, etc..

Although the lubrication requirements of diesel and petrol engines are different, the latest generation of lubricants generally meet many of the requirements for both diesel and petrol engine lubrication.

Yes, in emergency situations. Lubricants with similar properties and formulated for the same application can be mixed together, even when it comes to adding a mineral oil to a synthetic oil or vice versa. It must however be considered that the final performance of the mixture obtained could be very different and lower than the starting lubricants and therefore not suitable.

However, it is not recommended to use oils and products older than 5 years or if the package has not been properly stored.

Synthetic lubricants are formulated with base oils that are not directly derived from petroleum refining. Rather, they are made through an industrial chemical process. Synthetic bases give lubricants superior characteristics in terms of higher fluidity at low temperatures, better resistance to oxidation degradation at higher temperatures and less evaporability (lower oil consumption).

A synthetic product may sometimes, but not necessarily, be better than a mineral product. Its actual “value” may be judged based on final performance or referring to various technical assessments.

Brakes, oil or tires are the elements to which we certainly devote more attention, just as much care should be reserved for the shock absorbers. These, together with brakes and tires, are defined as the “safety triangle” of each vehicle, the maintenance of forks and shock absorbers is therefore essential in both the racing and road sectors.

Inside a shock absorber there is a gas tank: a small chamber separated from the oil by a piston or a membrane, which constantly holds the oil under pressure. When the gas pressure is lost with use, the shock absorber is said to be “exhausted”. The loss of pressure inside the shock absorber can lead to the formation of foam in the oil and consequently an apparent strong loss of viscosity. This compromises the performance of the shock absorber resulting “too soft” and generating an uncontrolled stroke.
To prevent this phenomenon, it is important to proceed with constant maintenance of the shock absorbers through the replacement of components and oil. Bardahl lubricants are equipped with the best anti-foam and anti-friction additives to ensure maximum driving comfort and safety.

The reports made by consumers regarding damage caused by poor quality fuels are increasingly frequent. This is a problem that should not be underestimated as it can cause significant damage and consequences to your vehicle.
The problems can be many and depend on various factors inherent to the fuel such as: the refining process, incorrect cleaning of the residues in the tanks in which it is stored or alterations dictated by the presence of water or other elements.
The engine components that are most susceptible to damage are those that affect the injection system. In most cases the problem can be solved with the correct prevention, while in the worst case the risk is that of having to replace the fuel pump or the injectors.

Bardahl has developed specific fuel additives for the prevention and care of the fuel system which, if used continuously, make it possible to drastically reduce the risks associated with the degradation of the systems.

1. Check the oil level and replace it if necessary.
This is an operation of primary importance: the engine oil level must be between the two minimum and maximum notches of the window on the engine block and it is always better not to blindly trust the electronic warning lights. If the oil levels are below the minimum, it is necessary to top up. The replacement including the filter (using the Bardahl type of oil which fulfills the specifications indicated by the manufacturer) must be performed within the intervals suggested by the manufacturer.

2. Check the coolant
The coolant protects the entire cooling system not only from overheating but also from corrosion and scale. For this reason, Bardahl has developed two practical and very valid solutions: prediluted and ready to use, the Coolant HOA Tech coolants, to be used in the cooling circuits of high-performance engines of motorcycles, scooters and quads, and Coolant OA Tech, for motorcycles that require premium “long life” OAT (Organic Acid Technology) fluids, these are the ideal products to protect radiators, cylinders, cylinder heads and water pumps even in the hottest months.

3. Check for proper operation of the brakes
Do not forget to check the level of the fluid for the hydraulic circuits of the braking system and the wear of the pads and discs: if the brake fluid level is low or deteriorated, it is necessary to proceed promptly with the change.
Bardahl products are excellent allies, first of all Brake Fluid Dot 4 brake oil, which can also be used in the event of particularly high temperatures, without the likelihood of the formation of dangerous vapor bubbles within the fluid (phenomenon of Vapor Lock). The product is suitable for the hydraulic circuits of disc brakes, drum brakes and clutches, of motorcycles and cars.
