156 Fuel and Refueling It is best not to alternate repeatedly between gasoline and E85. If you do switch fuels, it is recommended that you add as much fuel as possible-at least half a tank. Do not add less than five gallons (18.9 liters) when refueling. You should drive the vehicle immediately after refueling for at least 5 miles (8 kilometers) to allow the vehicle to adapt to the change in ethanol concentration. If you exclusively use E85 fuel, it is recommended to fill the fuel tank with regular unleaded gasoline at each scheduled oil change. Octane Recommendations 3.7L V6 engine and 3.5L V6 EcoBoost® engine "Regular" unleaded gasoline with a (R+M)/2 METHOD pump (R+M)/2 octane rating of 87 is recommended. Some stations offer fuels posted as "Regular" with an octane rating below 87, particularly in high altitude areas. Fuels with octane levels below 87 are not recommended. Premium fuel will provide improved performance and is recommended for severe duty usage such as trailer tow. 87 Do not be concerned if your engine sometimes knocks lightly. However, if it knocks heavily while you are using fuel with the recommended octane rating, see your authorized dealer to prevent any engine damage. RUNNING OUT OF FUEL Avoid running out of fuel because this situation may have an adverse effect on powertrain components. If you have run out of fuel: • You may need to cycle the ignition from off to on several times after refueling to allow the fuel system to pump the fuel from the tank to the engine. On restarting, crank time will be a few seconds longer than normal. With keyless ignition, just start the engine. Crank time will be longer than usual. • Normally, adding 1 gallon (3.8 liters) of fuel is enough to restart the engine. If the vehicle is out of fuel and on a steep grade, more than 1 gallon (3.8 liters) may be required. • The service engine soon indicator may come on. For more information on the service engine soon indicator, see Warning Lamps and Indicators in the Instrument Cluster chapter. 2014 MKS (mks) Owners Guide gf, 1st Printing, April 2013 USA (fus)

It is best not to alternate repeatedly between gasoline and E85. If you do
switch fuels, it is recommended that you add as much fuel as
possible—at least half a tank. Do not add less than five gallons
(18.9 liters) when refueling. You should drive the vehicle immediately
after refueling for at least 5 miles (8 kilometers) to allow the vehicle to
adapt to the change in ethanol concentration. If you exclusively use E85
fuel, it is recommended to fill the fuel tank with regular unleaded
gasoline at each scheduled oil change.
Octane Recommendations
3.7L V6 engine and 3.5L V6
EcoBoost® engine
“Regular” unleaded gasoline with a
pump (R+M)/2 octane rating of 87
is recommended. Some stations
offer fuels posted as “Regular” with an octane rating below 87,
particularly in high altitude areas. Fuels with octane levels below 87 are
not recommended. Premium fuel will provide improved performance and
is recommended for severe duty usage such as trailer tow.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily while you are using fuel with the recommended octane
rating, see your authorized dealer to prevent any engine damage.
RUNNING OUT OF FUEL
Avoid running out of fuel because this situation may have an adverse
effect on powertrain components.
If you have run out of fuel:
You may need to cycle the ignition from off to on several times after
refueling to allow the fuel system to pump the fuel from the tank to
the engine. On restarting, crank time will be a few seconds longer
than normal. With keyless ignition, just start the engine. Crank time
will be longer than usual.
Normally, adding 1 gallon (3.8 liters) of fuel is enough to restart the
engine. If the vehicle is out of fuel and on a steep grade, more than
1 gallon (3.8 liters) may be required.
The service engine soon indicator may come on. For more information
on the service engine soon indicator, see

Indicators
