Only fuel that does not contain tetraethyl lead should be used to refuel your vehicle. The fuel tank filler neck has a special tube into which only the thinner barrel of a gun designed for filling with tetraethyl lead-free gasoline can be inserted.
Warning: If you fill your vehicle with fuel containing tetraethyl lead, it may damage the catalytic converter. In this case, it will not be subject to warranty repair.
Fuel additives
Many gasoline manufacturers add special fuel additives to their gasoline to help reduce the formation of deposits on the intake manifold and injectors. It is recommended to use gasoline with fuel additives for refueling the car. They help maintain good engine and emission control system performance.
Fuel octane requirements
For all vehicles other than those with a double overhead camshaft engine, tetraethyl lead-free petrol with a minimum octane rating of 87 [(R+M)] must be used./2] or 91.
All vehicles equipped with a DOHC engine must use unleaded gasoline with a minimum octane rating of 91 [(R+M)/2] or 95. If you cannot obtain gasoline with such a high octane rating, gasoline with an octane rating of 87 [(R+M)/2] or 91 can be used. However, in this case, engine power will be reduced.
Oxidized gasoline
Some gas stations sell gasoline based on ethyl alcohol, methyl alcohol, or trimethylbutyl ether, although they may be called differently.

Using this type of fuel is not recommended unless you are sure that its composition is suitable for your vehicle.
Ethanol
Mixture of 10% ethanol (ethyl alcohol) and 90% of tetraethyl lead-free gasoline can be used to fill a vehicle if its octane rating is not lower than the recommended one.
Methanol
Do not use gasoline containing methanol (methyl alcohol), for refueling a car. Using such gasoline can cause problems with engine operation and lead to failure of some important components of the fuel system.
Trimethylbutyric ether
A mixture of 15% or less trimethyl butyl ether and tetraethyl lead-free gasoline may be used to fill a vehicle if its octane rating is not lower than the recommended octane rating.
Caution: If you are experiencing engine performance problems and believe that the type of fuel you are using is the cause, try switching to a different fuel.
