Refuelling
WARNING
Petrol fumes are highly explosive. Bear
therefore in mind:
• Never smoke while refuelling.
• Never use petrol for any purpose
other than as fuel for your car.
• Petrol is extremely flammable and can
cause severe burns. No naked flames
near petrol.
• Do not use a mobile phone at the
same time as refuelling.
• If the car has a fuel-driven heater, this
must be turned off for refuelling.
Only use fuel grades from a well-known oil
company.
All Cadillac petrol engines can be driven
on petrol with an octane rating between
91 RON and 98 RON (RON = Research
Octane Number).
The engine management system monitors
the combustion and automatically adapts to
the fuel used.
Always use the correct grade of fuel:
unleaded 91–98 RON.
NOTICE
• Do not overfill. Fuel should not come
right up the filler pipe as room for
expansion is needed for when the
temperature rises.
• The use of fuel with too low an octane
rating can cause serious engine
damage.
Starting and driving
133
For optimum performance we recommend:
• RON 95 for 4-cyl. petrol engines.
• RON 98 for 2.8 V6.
• E85 for cars adapted to run on E85
E85 fuel must fulfil the CWA 15293 or
SS 155480 standard.
• Diesel fuel for diesel engines.
Diesel engines must be run on diesel fuel
that fulfils the EN590 European standard.
Sometimes, petrol can contain a number of
additives containing oxygen. The most
common of these are alcohol or some type
of ether. The maximum oxygen level is
restricted by national regulations.
If fuel containing a mixture of alcohol is
used, the maximum levels approved by
Cadillac are: 5% by volume of methanol;
or 10% by volume of ethanol. The most
common type of ether used is MTBE
(methyl-tertiary-butyl-ether), of which fuel
may contain a maximum of 15% by volume.
The fuel filler cap is located in the right-hand
rear wing.
