Hyundai vehicles equipped with Fuel Injection (petrol) manufactured after 31st October 2003 are equipped with fuel systems compatible with alcohol (Ethanol).
These vehicles can operate on a maximum of 10% Ethanol / 90% unleaded petrol, however if drive ability is affected, the use of 100% unleaded fuel is recommended. Ethanol blended fuel mixed at 10% is generally referred to as E10.
Hyundai vehicles equipped with Fuel Injection (petrol) manufactured before October 2003 do not have fuel systems compatible with alcohol (Ethanol). If Ethanol is to be used in these vehicles, then a maximum of 10% Ethanol / 90% unleaded fuel (E10) can be used in conjunction with periodic use of a fuel corrosion inhibitor. (The Hyundai recommended inhibitor is available under part number AL009M0002). This can be purchased at any authorised Hyundai Dealership. To find your nearest dealer please visit Find-a-Dealer.
Hyundai vehicles equipped with carburettor fuel supply systems should not be run on Ethanol blended fuel of any ratio. This is due to both the incompatibility of the fuel lines with the moisture holding characteristics of Ethanol, and to the negative effect on vehicle performance due to the variation of vapour pressures between petrol and Ethanol.
