Why are additives used?

A good example is "Winterdiesel": On cold days, diesel fuel can 'coagulate' such that the fuel filter is clogged and the vehicle stops running. With a so-called Flow Guard, which can also be added in the refinery, the diesel fuel's resistance to the cold is increased.

There are enormous amounts of different active ingredients which are used as additives. The active ingredient or combination of ingredients which is/are used depends on a variety of factors. Of course, it depends first and foremost on the energy carrier. The bandwidth extends from heating oil and diesel to petrol, and also includes liquefied petroleum gas and lubricants. However, it is crucial where the fuel or lubricant is used and which effect should be achieved with the use of an additive.

The benefits at a glance

  • Extending the storage life of fuels
  • cleaning and maintaining cleanliness of fuel systems and heating oil tanks
  • suppressing the odour of heating oil
  • optimising combustion
  • ensuring better performance and lower emissions
  • improving lubricating ability
  • increasing octane and cetane number.

Additives assure functionality

Additives are necessary to produce fuels in compliance with European Norm Standard (EN). All refineries and import tankers use additives. In this case, however, it is not a matter of producing a premium product, but the ability to deliver products which satisfy requirements within an economically acceptable framework. So there are additives in every litre of diesel which is solid in Europe at petrol stations, but that does not automatically make it a premium product. Today there is essentially no fuel without additives.

Additives are recommended

Institut für Wärme und Oeltechnik [Institute for Heat and Oil Technology] (IWO) confirms: 'Additives improve product characteristics. Additives are additional components which improve specific characteristics of heating oil. They can be added in the refinery or directly on site when refuelling.' Premium heating oil is evaluated with an additional additive package, wherein specific product characteristics are improved and problem-free use is assured, even after extended storage.

Additives reduce costs

Additives optimise the fuel or heating fuels on their own or the function of fuel-carrying systems. They optimise combustion and thus contribute to compliance with emissions limits (e.g. the Euro 6 standard or those of the German Federal Emission Control Act). With additives, better fuel qualities can be produced or fuels can be improved to the quality level that is necessary to meet the requirements of today's engines or burners.

Renowned manufacturers recommend premium heating oil


'Viessmann oil heating boilers can be operated with all commercially available low-sulphur heating oils (extra light). Low-sulphur heating oil in premium quality is recommended.'



'As a leading provider of modern oil heating boilers, Buderus recommends the use of low-sulphur heating oil, preferably in automatically dosed and premixed premium quality [...]'



'WOLF recommends the use of low-sulphur heating oil for all oil heating boilers, preferably in premium quality [...]'


ERC is the expert

ERC is the expert when it comes to combining various components for various applications to create a functioning additive package. It sounds simple, but is an art, because not all active ingredients are compatible. ERC has mastered the art of chemical additives. As a result, our product range and our know-how 'Made in Germany' are also being requested increasingly on an international level - simply based on recommendations and without cost-intensive marketing campaigns.

Additional evidence of the efficiency of our additives has been demonstrated on burner test stands, in field tests with passenger and commercial vehicles, and in motor sport. Our products bear the TÜV seal, have been tested together with leading manufacturers, and are used in motor sports in order to further improve performance.
