Besides acting as fuel, petrol also functions as lubricating product for the mechanical components in the fuel system of cars. By fuel system we mean all components that are in contact with fuel, from tank up to injectors.
Ethanol is a very lean product that has no lubricating properties at all. As a matter of fact ethanol has corroding effects on metal surfaces and it dries out rubber hoses.
Increasing ethanol % in fuel therefore has a negative effect on the durability of fuel system components.
JLM offers fuel additives that prevent the negative effects of ethanol on metal components in the fuel system, by means of adding corrosion inhibitors to the fuel. Furthermore the JLM fuel additives contain detergents the clean carbon deposits from the intake system, injectors and inlet valves.
Less carbon deposits on the surfaces in the combustion chamber means a more efficient combustion process and more powerful engine output.
"Generally most cars are ok with fuel blends up to E10, and our additives also work in E10 fuels. With older vehicles (classic/vintage cars etc.) there can sometimes be concerns about the elastomers used in their fuel systems and ethanol. However, no additive can stop this ethanol/elastomer interaction, despite many aftermarket products, which claim such an effect.
Besides the elastomers, the main issue with E10 in classic cars is the fuel stability.
Many classics do not run for so many miles and therefore the fuel remains in the vehicle for a long time, especially over the winter. There is product available to provide some detergency and storage stability to the fuel preventing corrosion and acid formation in storage."
