gas type OPEL ASTRA K 2018 Owner's Manual

106Instruments and controlsTachometer
Displays the engine speed.
Drive in a low engine speed range for each gear as much as possible.
Caution
If the needle is in the red warning
zone, the maximum permitted
engine speed is exceeded. Engine at risk.
Fuel gauge
Displays the fuel level or gas content
(CNG) in the tank depending on the current operation mode.
The arrow indicates the vehicle side
where the fuel filler flap is located.
For bi-fuel engines, the Driver
Information Centre displays the fuel
level for the fuel type which is
currently not in operation. The fuel
level for the fuel type which is
currently in operation is shown in the fuel gauge.
Control indicator Y illuminates if the
level in the tank is low. Refuel
immediately if it flashes.
Never run the fuel tank dry.
Because of the fuel remaining in the
tank, the top-up quantity may be less
than the specified fuel tank capacity.
Fuel selector
Natural gas operation (CNG)
Press X to switch between petrol and
natural gas operation.
The LED status shows the current
operating mode.

Driving and operating221The capacity of the natural gas tank
depends on outside temperature,
filling pressure, gas composition and type of refuelling system. Capacities
3 292.

Fuel consumption - CO 2-
Emissions
Petrol and Diesel engines
The fuel consumption (combined) of
the model Opel Astra is within a range of 6.2 to 3.3 l/100 km.
The CO 2 emission (combined) is
within a range of 142 to 88 g/km.
For the values specific for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
Natural gas enginesThe gas consumption (combined) of
the model Opel Astra is
4.5 kg/100 km.
The CO 2 emission (combined) is
123 g/km.For the values specific to your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
General information The official fuel consumption and
specific CO 2 emission figures quoted
relate to the EU base model with
standard equipment.
Fuel consumption data and CO 2
emission data are determined
according to regulation R (EC)
No. 715/2007 (in the latest applicable version), taking into consideration the
vehicle weight in running order, as specified by the regulation.
The figures are provided only for the
purpose of comparison between
different vehicle variants and must
not be taken as a guarantee for the
actual fuel consumption of a
particular vehicle. Additional
equipment may result in slightly
higher results than the stated
consumption and CO 2 figures.

278Service and maintenanceDexos is the newest engine oil quality
that provides optimum protection for
gasoline and diesel engines. If it is unavailable, engine oils of other listed qualities have to be used.
Recommendations for gasoline
engines are also valid for
Compressed Natural Gas (CNG),
Liquified Petroleum Gas (LPG) and
Ethanol (E85) fuelled engines.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 282.
Topping up engine oilCaution
In case of any spilled oil, wipe it up and dispose it properly.
Engine oils of different manufacturersand brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use of engine oils for all petrol
engines with only ACEA quality is
prohibited, since it can cause engine
damage under certain operating
conditions.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 282.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity grades
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade depending on the minimum ambient
temperature 3 282.All of the recommended viscosity
grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only organic acid type-long life
coolant (LLC) antifreeze approved for
the vehicle. Consult a workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant
provides frost protection down to
approx. -37 °C. This concentration
should be maintained all year round.
The use of additional coolant
additives that intend to give additional
corrosion protection or seal against
minor leaks can cause function
problems. Liability for consequences resulting from the use of additional
coolant additives will be rejected.
