Fuel; Fuel For Petrol Engines - Opel Adam 1.0 2019 Owner's Manual

Fuel

Fuel for petrol engines

Only use unleaded fuel that complies
with European standard EN 228 or
equivalent.
The engine is capable of running with
fuel that contains up to 10% ethanol
(e.g. named E10).
Use fuel with the recommended
octane rating. A lower octane rating
can reduce engine power and torque
and slightly increases fuel
consumption.
Caution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.
Caution
Use of fuel that does not comply to
EN 228 or equivalent can lead to
deposits or engine damage.
Caution
Use of fuel with a lower octane
rating than the lowest possible
rating could lead to uncontrolled
combustion and engine damage.
The engine-specific requirements
regarding octane rating are given in
the engine data overview 3 206. A
country-specific label at the fuel filler
flap can supersede the requirement.
Driving and operating
Fuel additive
Fuel should contain detergent
additives that help prevent engine
and fuel system deposits from
forming. Clean fuel injectors and
intake valves will allow the emission
control system to work properly. In
certain countries fuel does not
contain sufficient quantities of
additive to keep fuel injectors and
intake valves clean. In these
countries a fuel additive is required for
some engines to make up for this lack
of detergency. Only use fuel additive
approved for the vehicle.
Adding fuel additive to the filled fuel
tank is required at least every 15,000
km or after one year, whichever
occurs first. For further information,
contact your workshop.
Prohibited fuels
Fuels containing oxygenates such as
ethers and ethanol, as well as
reformulated fuel, are available in
some cities. If these fuels comply with
the previously described
specification, then they are
acceptable to use. However, E85
