Fuel; Recommended Fuel; Fuel Additives - Cadillac 2014 Escalade ESV Owner's Manual

Fuel

Use the recommended fuel for
proper vehicle maintenance.

Recommended Fuel

Use premium unleaded petrol with a
stated octane rating of 97 RON or
higher. Regular unleaded petrol
rated 95 RON or higher can be
used, but acceleration could be
reduced, and an audible knocking
noise may be heard. If the octane is
less than 97 RON, a heavy
knocking noise may be heard. If this
occurs, use a petrol rated at 97
RON or higher as soon as possible.
Otherwise, the engine could be
damaged. If heavy knocking is
heard when using petrol rated at 97
RON or higher, the engine needs
service.
Use of Seasonal Fuels
Use summer and winter fuels in the
appropriate season. Driving or
starting could be affected if the
incorrect fuel is used. Drive the
vehicle with the engine running until
the fuel is a half tank or less, then
refuel with the current seasonal fuel.
Prohibited Fuels
Petrols containing oxygenates, such
as ethers and ethanol, as well as
reformulated petrols are available in
some cities. If these petrols 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 flex fuel
vehicles.
Notice: Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under the
vehicle warranty.
Some petrols that are not
reformulated for low emissions can
contain an octane-enhancing
additive called
methylcyclopentadienyl manganese
Driving and Operating
tricarbonyl (MMT). Do not use
petrols with MMT as they can
reduce spark plug life and affect
emission control system
performance. The malfunction
indicator lamp may turn on. If this
occurs, see your dealer for service.

Fuel Additives

Petrol 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 petrol 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, part number
88861013 to the fuel tank at every
engine oil change or every
15 000 km, whichever occurs first.
