Fuel Additives; Filling The Tank - Cadillac 2015 ATS Owner's Manual

vehicle until the fuel is at one-half
tank or less, then refuel with the
current seasonal fuel.
Prohibited Fuels
Petrol containing oxygenates such
as ethers and ethanol, as well as
reformulated petrol, is 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 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.
That damage would not be
covered under the vehicle
warranty.
Some petrol, mainly high octane
racing petrol, can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). Do not use petrol
and/or fuel additives 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 to the fuel tank at
every engine oil change or every
15,000 km, whichever occurs first.
It is available at your dealer.
