BMW FUEL ADDITIVES AND ADBLUE ADDITIVE.

CARING FOR YOUR ENGINE.

BMW PETROL & DIESEL ADDITIVES

Most of us assume that all we need to put in our tanks is the fuel we buy at the pumps. But we may not be aware that fuel quality can vary significantly, and that poor quality fuel coupled with modern driving, such as short urban journeys, can cause a build-up of deposits in the fuel system. These deposits can impact performance and shorten the lifespan of the engine and fuel system components.

That is why BMW have developed Petrol & Diesel Additives to help clean away the deposits that form in fuel injectors, intake valves and combustion chambers whilst you're driving. Used regularly they work as a preventative tool, cleaning and maintaining your fuel system and prolonging the life of your engine.

POOR FUEL QUALITY CAN CAUSE:

• Loss of engine power.
• Rough idling.
• Increased fuel consumption.
• Higher exhaust emissions.
• Reduced engine lifespan. 
• Failure of the emissions element in an MOT test.

BMW FUEL ADDITIVE BENEFITS:

• Cost-effective solution to prolonging engine life.
• Cleans and maintains the fuel system of your car.
• Removes deposits on intake valves, fuel injectors and combustion chambers.
• Can improve fuel consumption* and engine performance.
• Compatible with all BMW petrol and diesel engines.

WHY SHOULD I USE BMW FUEL ADDITIVES?

These are the only Fuel Additives rigorously tested and approved by BMW. Used regularly they will clean and maintain the fuel system of your car, resulting in better fuel consumption and engine performance. 

HOW OFTEN SHOULD I USE BMW FUEL ADDITIVES?

One bottle of additive to one full tank of fuel is suggested by BMW, so there is no set frequency based on miles driven, as each owner will achieve a different mpg according to their driving style.

WILL USING BMW FUEL ADDITIVES CAUSE ANY HARM TO MY CAR?

The technology used in BMW's Fuel Additives is fully compatible with the additives already found in some fuel sold at petrol stations. Using them with fuel that already contains a detergent additive will not harm your engine. 

*mpg is also dependent on driving style and age of vehicle.

ADBLUE

AdBlue is a vital additive to certain BMW models* as part of the environmentally-friendly EU6 regulations, to significantly reduce nitrogen oxide (NOx) emissions from diesel engines.

A selection of BMW models are already fitted with a NOx Storage Catalyst that absorbs nitrogen oxide, but for the models that do not have this, an alternative system, Selective Catalytic Reduction (SCR), is used in order to reduce their NOx emissions.

AdBlue is used for those models fitted with an SCR system. AdBlue is a liquid solution of urea, and when it meets a hot exhaust system it releases ammonia, which is a catalyst to a chemical reaction that converts NOx into harmless water vapour and nitrogen.

AdBlue is poured into a small dedicated tank into the car and, when full, will last for approximately 9000 miles. You can easily fill it yourself, but we recommend having it filled by our expert BMW trained technicians to ensure it’s done accurately, while you can sit back and relax, knowing that your BMW is in safe hands.

If filling yourself, check your BMW to see where the AdBlue tank is, as some models have the tank by engine compartment, and others by the fuel tank.

BMW’s that require AdBlue will have a warning symbol appear on their dash, informing you when the AdBlue is approaching the need of a refill. It’s important to adhere to the symbol information, as letting the AdBlue tank run empty will stop your engine from starting once it has been turned off if there is no AdBlue present.

BMW AdBlue Symbol Guide:

An AdBlue refill is available from all Barons and Chandlers BMW Centres.

*The main BMW models that have SCR systems are the BMW 5 Series and BMW X5 models, however other models may have the SCR system fitted. Please check with your local BMW Centre for more information.
