Refueling Fires Cellphones
The RF energy from a cellphone can cause a sparking on bare metal, much like aluminum foil in a microwave oven. The spark could ignite gasoline fumes present while refueling.
Refueling Fires Static Electricity
Static discharge from your body can ignite gasoline fumes present when you get back out of the vehicle and touch the fuel nozzle.
Risk of fire during refueling
Fuel is highly flammable, can deflagrate or explode.
Fuel vapors and skin contact with fuel
Fuel and fuel vapors are harmful to health.
To prevent damage to the emission control system and engine:
In some cases, fuels have a high sulfur content. As a result, under certain driving conditions, combustion in the engine can lead to output of unpleasant odors (known as the "odor of rotten eggs"). Porsche is not responsible for this circumstance and it does not indicate a vehicle fault.
The contents of the tank are displayed on the instrument panel when the ignition is switched on.
If an amount less than the model-dependent residual quantity remains in the fuel tank, the warning light on the multifunction display in the instrument panel lights up when the ignition is switched on or the engine is running.
Selecting suitable fuels
Unsuitable fuels may damage the engine as well as the fuel and exhaust system.
Information regarding fuel quality can normally be found on the fuel pump. Gas station employees can also provide information.
Unleaded fuels may not be available outside the continental U.S. and Canada.
The engine is designed for unleaded fuels without metallic additives.
Octane rating indicates a fuel’s ability to resist detonation. Therefore, buying the correct octane gas is important to prevent engine “damage”. The RON octane rating is based on the research method. The CLC (U.S. Cost of Living Council octane rating) or AKI (antiknock index) octane rating usually displayed on U.S. fuel pumps is calculated as research octane number plus motor octane number, divided by 2.
The CLC or AKI octane rating is usually lower than the RON rating:
For example: 95 RON equals 90 CLC or AKI. The engine has been optimally designed for unleaded fuel without metallic additives and with octane levels of 98 RON/88 MON (93 CLC or AKI).
The engine is suited to operation with fuel containing up to 15% ethanol. The use of fuels containing ethanol may lead to an increase in fuel consumption.
