Fuel For Diesel Engines - Vauxhall Insignia Owner's Manual

180 Driving and operating
If access to E85 is limited then fuel
with a different proportion of ethanol
or normal RON 95 can be used for
refuelling. The engine's control
management system is adjusted
automatically according to the
amount of ethanol in the fuel.
E85 fuel must fulfil the CWA 15293 or
SS 155480 standard.
When the temperature is about
-10 °C or lower a greater proportion of
petrol should be used. E85 in
combination with low temperatures
could lead to the car being more
difficult to start. A slightly higher
proportion of petrol improves the cold
start properties considerably.
During the engine's warm-up phase
(below +50 °C) engine torque is
limited when driving with a proportion
of ethanol.
Ethanol contains less energy per litre
than petrol, which is why fuel
consumption increases when driving
on E85 compared with petrol. A
consequence of this is that a tank of
E85 covers fewer miles than a tank of
petrol.
Caution
Certain additives in petrol could, in
combination with ethanol, cause
reduced driveability. For this
reason, refuel with a full tank of
petrol every 6000 miles. Use up
the majority of this before
refuelling the car again.

Fuel for diesel engines

Only use diesel fuel that complies
with EN 590.
Usage of fuel with quality, not
complying to the Technical
Regulations in effect (Decree № 118
of 27.02.2008 with amendments of
30.12.2008 № 1076) can lead to
engine damage and loss of all
warranty obligations.
In countries outside the European
Union use Euro-Diesel fuel with a
sulfur concentration below 50 ppm.
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.
Fuel for liquid gas
operation
Liquid gas is known as LPG
(Liquefied Petroleum Gas) or under
its French name GPL (Gaz de Pétrole
Liquéfié). LPG is also known as
Autogas.
LPG consists mainly of propane and
butane. The octane rating is between
105 and 115, depending on the
butane proportion. LPG is stored
liquid at around 5 - 10 bar pressure.
