The reason for this is the bio-content prescribed by law and the EU in all current fuels, i.e. there is currently no fuel without bio-content!

Even the so-called premium fuels contain an organic component, albeit to a lesser extent.

 

What does biofuel or fuel with bio content mean?

Gasoline is referred to as E5, which means that the national average of ethanol (bio proportion) in gasoline is 5%. Spot checks at filling stations have even revealed concentrations of up to 10%.

Diesel is referred to as B7, which means that the national average of biodiesel (organic content) in diesel is 7 %. Here, too, concentrations of over 10% have been found in random samples at filling stations.

Why does the organic content in fuels cause such problems for our engines?

Small amounts of the bio-component from the fuels enter the engine oil via the combustion process in the cylinder and accumulate there over time.

During the injection process through the injection nozzles, some of the fuel condenses on the cylinder walls and passes from there past the piston rings into the engine oil.

The normal operating temperature of the engine and therefore also the normal oil temperature is not sufficient to remove (evaporate) these bio-inputs from the engine oil.

Gasoline vehicles

The ethanol from the gasoline leads to an accumulation of water in the engine oil. This accumulation of water leads to increased corrosion in the engine. The result of this corrosion is increased wear and the formation of deposits throughout the engine. Other components of ethanol further support the formation of deposits.

In addition, the ethanol in the petrol also causes water to accumulate in the fuel, which also leads to corresponding corrosion and deposits in the entire fuel system. This results in poorer combustion and an inefficient fuel yield, which unnecessarily increases fuel consumption.

Diesel vehicles

The biodiesel (organic content) in diesel also enters the engine oil during the combustion process in the cylinder and accumulates there over time. The main problem with biodiesel is not the accumulation of water, but the dilution of the engine oil.

The biodiesel forms a compound with the engine oil, which negatively changes the viscosity (flowability); the engine oil increasingly loses its lubricity! This also results in an increased ageing process of the engine oil.

In the fuel system, the biodiesel content in the diesel forms more deposits, which leads, for example, to a negative change in the spray pattern of the injection nozzles. Poorer combustion and inefficient fuel yield (increased consumption, more emissions) are the inevitable result.

In addition, the sulphur content in diesel has been reduced more and more in recent years in order to reduce exhaust emissions. For the sensitive fuel systems (e.g. CDI and TDI), this results in poorer lubrication and therefore increased wear.
