*1. Fuel additives
Kia recommends that you use Tier 1
unleaded gasoline which has an octane
rating of RON (Research Octane Num-
ber) 95/AKI (Anti Knock Index) 91 or
higher.
For customers who do not use good
quality gasolines including fuel addi-
tives regularly, and have problems start-
ing or the engine does not run smoothly,
one bottle of additives should be added
to the fuel tank at every 8,000 miles
(13,000 km).
Additives are available from an autho-
rized Kia dealer. Do not mix with other
additives.
*2. Engine oil and engine oil filter
As it is normal for engine oil to be con-
sumed during driving, the engine oil
level should be checked on regular
basis.
The engine oil change interval for nor-
mal operating conditions is based on the
use of the recommended engine specifi-
cation. If the recommended engine oil
specification is not used, then replace
the engine oil according to the mainte-
nance schedule under severe operating
conditions.
*3. Coolant (Engine)

ized water or soft water for your vehicle
