2018 VAUXHALL INSIGNIA engine

230Driving and operatingFuel
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 3 291. A
country-specific label at the fuel filler
flap can supersede the requirement.
Fuel additives outside Europe
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.
Some fuel does not contain sufficient
quantities of additive to keep fuel
injectors and intake valves clean.
To make up for this lack of
detergency, add Fuel System
Treatment PLUS to the fuel tank at
every engine oil change or every
10,000 miles, whichever occurs first. It is available at your workshop.
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
(85% ethanol) and other fuels
containing more than 15% ethanol
must be used only in FlexFuel
vehicles.Caution
Do not use fuel containing
methanol. It can corrode metal
parts in the fuel system and also
damage plastic and rubber parts.
This damage would not be
covered by the vehicle warranty.

Driving and operating231Some fuels, mainly high octane
racing fuels, can contain an octane
enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). Do not use fuels or
fuel additives with MMT as they can
reduce spark plug life and affect
emission control system
performance. The malfunction
indicator light Z may turn on 3 107.
If this occurs, seek the assistance of
a workshop.
Fuel for diesel enginesOnly use diesel fuel that complies
with EN 590 and which has a sulphur
concentration of max. 10 ppm.
Fuels with a biodiesel (compliant with
EN 14214) content of max. 7% by
volume may be used (e.g. named
B7).
If travelling in countries outside the
European Union occasional use of Euro-Diesel fuel with a sulphur
concentration below 50 ppm is
possible.Caution
Frequent usage of diesel fuel containing more than 15 ppm
sulphur will cause severe engine
damage.
Caution
Use of fuel that does not comply to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and may affect
your warranty.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
Low temperature operation At temperatures below 0° C, some
diesel products with biodiesel blends may clog, freeze or gel, which mayaffect the fuel supply system. Starting
and engine operation may not work
properly. Make sure to fill winter
grade diesel fuel at ambient
temperatures below 0°C.
Arctic grade diesel fuel can be used
in extreme cold temperatures below
-20° C. Using this fuel grade in warm
or hot climates is not recommended
and may cause engine stalling, poor starting or damage on the fuel
injection system.
Refuelling

234Driving and operatingDriving characteristics andtowing tips
Before attaching a trailer, lubricate the coupling ball. However, do not do
so if a stabiliser, which acts on the coupling ball, is being used to reduce snaking movements.
During trailer towing do not exceed a
speed of 50 mph. A maximum speed
of 60 mph is only appropriate if an
oscillation damper is used and the
permissible gross trailer weight does
not exceed the vehicle's kerb weight.
For trailers with low driving stability
and caravan trailers, the use of an
oscillation damper is strongly
recommended.
If the trailer starts snaking, drive more slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 300.Trailer towing
Trailer loads The permissible trailer loads are
vehicle and engine-dependent
maximum values which must not be
exceeded. The actual trailer load is the difference between the actual
gross weight of the trailer and the
actual coupling socket load with the
trailer coupled.
The permissible trailer loads are
specified in the vehicle documents. In general, they are valid for gradients
up to 12%.
The permissible trailer load applies
up to the specified incline and at sea
level. Since engine power decreases
as altitude increases due to the air
becoming thinner, therefore reducing
climbing ability, the permissible gross
train weight also decreases by 10%
for every 1000 metres of altitude. The gross train weight does not have to be
reduced when driving on roads with
slight inclines (less than 8%, e.g.
motorways).The permissible gross train weight
must not be exceeded. This weight is specified on the identification plate
3 286.
Vertical coupling load
The vertical coupling load is the load
exerted by the trailer on the coupling
ball. It can be varied by changing the
weight distribution when loading the
trailer.
The maximum permissible vertical
coupling load of 60 kg
(engines B20DTH / B20NFT: 90 kg) is
specified on the towing equipment
identification plate and in the vehicle
documents. Always aim for the
maximum load, especially in the case
of heavy trailers. The vertical coupling load should never fall below 25 kg.

Driving and operating235Rear axle loadWhen the trailer is coupled and the
towing vehicle fully loaded, the
permissible rear axle load (see
identification plate or vehicle
documents) may be exceeded by
70 kg (engines B20DTH: 80 kg), the
gross vehicle weight rating must not
be exceeded. If the permissible rear
axle load is exceeded, a maximum
speed of 60 mph applies.
Towing equipmentCaution
The folding coupling ball bar
cannot be removed from the
vehicle. When driving without a
trailer, fold in the coupling ball bar.
9 Warning
Make sure that no one is in the
pivot zone of the coupling ball bar. Risk of body injury.
When releasing the stowed
coupling ball bar, make sure to
stand left of the grip.
Release stowed coupling ball bar
Pull the grip located left to the number
plate under the rear bumper fascia at an angle of approx. 45° to the ground.
A buzzing tone sounds as a warning
when the release handle is pulled out and the ball neck is disengaged.
Take the released coupling ball bar
and raise it up until it engages.
Ensure the coupling ball bar is
correctly engaged and the released
handle is guided back to its hidden
initial position, otherwise the buzzing tone will not stop.

236Driving and operatingStow/hide coupling ball bar
Pull the grip located left of the number
plate under the rear bumper fascia at an angle of approx. 45° to the ground.
A buzzing tone sounds as a warning
when the release handle is pulled out and the ball neck is disengaged.
With the flat of the hand, swivel the
released coupling ball bar to the right
until it engages under the floor. Make sure that the release handle is back inits hidden initial position, otherwise
the buzzing tone will not stop.
9 Warning
Towing a trailer is permitted only
when the coupling ball bar is fitted correctly. If the coupling ball bar
does not engage correctly or if the
release handle is impossible to guide to its hidden initial position in the housing or if the buzzing tone
sounds after engaging the
coupling ball bar, seek the
assistance of a workshop.
Eye for break-away stopping cable
Attach break-away stopping cable to
eye.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle/trailer combination is
selectively braked until the snaking ceases. While the system is working
keep steering wheel as still as
possible.
Trailer stability assistant is a function
of the Electronic Stability Control
3 182.
