611 *Technical data
Service products and capacities

Fuel requirementsOnly use premium unleaded fuel:\4
The octane number (posted at the
pump) must be 91 min. It is an aver-
age of both the Research (R) octane
number and the Motor (M) octane
number: (R+M) / 2). This is also
known as the ANTI-KNOCK INDEX.
Unleaded gasoline containing oxygen-
ates such as ethanol, IPA, IBA and TBA
can be used provided the ratio of any
one of these oxygenates to gasoline
does not exceed 10%; MTBE not to
exceed 15%.The ratio of methanol to gasoline must
not exceed 3% plus additional cosol-
vents.
Using mixtures of ethanol and methanol
is not allowed. Gasohol, which contains
10% ethanol and 90% unleaded gasoline,
can be used.
These blends must also meet all other
fuel requirements, such as resistance to
spark knock, boiling range, vapor pres-
sure, etc. Do not exceed an engine speed
of 3000 rpm if the vehicle is loaded
with a light load, such as two persons
and no cargo.
Do not exceed
2/3 of maximum ac-
celerator pedal position if the vehicle
is fully loaded or operating in moun-
tainous terrain.
