Fuel Additives; Filling The Tank - GMC 2018 Terrain Owner's Manual

Fuel Additives

Gasoline 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 gasoline does not contain
sufficient quantities of additives to
keep fuel injectors and intake valves
clean. To make up for this lack of
detergency, consult your dealer for
the GM approved additive
treatment. Add this additive to the
fuel tank at every engine oil change
or every 15 000 km (9,000 mi),
whichever occurs first.
