Do not use fuels that are labeled at the fuel pump as containing metals.
Only refuel with lead-free gasoline without
metal additives
Do not refuel with leaded gasoline or gasoline
with metal additives, e. g., manganese or iron;
otherwise, the catalytic converter and other
components will be permanently damaged.◀

ethanol content of 85 %, or with Flex Fuel, as this
would damage the engine and fuel supply system.◀

This gasoline is highly recommended.
However, you may also use gasoline with less AKI. The minimum AKI Rating is:

This has no affect on the engine life.
