KIA Optima 2012 - Manual (Page 16)

Introduction
4 1
Use of MTBE
Kia recommends avoiding fuels contain-
ing MTBE (Methyl Tertiary Butyl Ether)
over 15.0% vol. (Oxygen Content 2.7%
weight) in your vehicle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may
reduce vehicle performance and produce
vapor lock or hard starting.
Do not use methanol
Fuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components of
the fuel system.
Fuel Additives
Kia recommends that you use good qual-
ity gasolines treated with detergent addi-
tives such as TOP TIER Detergent
Gasoline, which help prevent deposit for-
mation in the engine. These gasolines
will help the engine run cleaner and
enhance performance of the Emission
Control System. For more information on
TOP TIER Detergent Gasoline, please
go to the website (www.toptiergas.com).
For customers who do not use TOP Tier
Detergent Gasoline regularly, and have
problems starting or the engine does not
run smoothly, additives that you can buy
separately may be added to the gasoline.
If TOP TIER Detergent Gasoline is not
available, one bottle of additive added to
the fuel tank at every 12,000 km or every
engine oil change is recommended.
Additives are available from your author-
ized Kia dealer along with information on
how to use them. Do not mix other addi-
tives.
Operation in foreign countries
If you are going to drive your vehicle in
another country, be sure to:
• Observe all regulations regarding reg-
istration and insurance.
• Determine that acceptable fuel is avail-
able.
No special break-in period is needed. By
following a few simple precautions for the
first 1,000 km (600 miles) you may add to
the performance, economy and life of
your vehicle.
• Do not race the engine.
• While driving, keep your engine speed
(rpm, or revolutions per minute)
between 2,000 rpm and 4,000 rpm.
• Do not maintain a single speed for long
periods of time, either fast or slow.
Varying engine speed is needed to
properly break-in the engine.
• Avoid hard stops, except in emergen-
cies, to allow the brakes to seat prop-
erly.
• Don't let the engine idle longer than 3
minutes at one time.
• Don't tow a trailer during the first 2,000
km (1,200 miles) of operation.
CAUTION
Your New Vehicle Limited Warranty
may not cover damage to the fuel
system and any performance prob-
lems that are caused by the use of
fuels containing methanol or fuels
containing MTBE (Methyl Tertiary
Butyl Ether) over 15.0% vol.
(Oxygen Content 2.7% weight.)
