2011 KIA Optima engine

Introduction
Your new KIA vehicle is designed to use
only unleaded fuel having a pump octane
number ((R+M)/2) of 87 (Research
Octane Number 91) or higher.
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust emis-
sions and spark plug fouling.Gasoline containing alcohol andmethanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alcohol),
and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or instead
of leaded or unleaded gasoline.
Do not use gasohol containing more than
10% ethanol, and do not use gasoline or
gasohol containing any methanol. Either
of these fuels may cause drivability prob-
lems and damage to the fuel system.
Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or drivability problems
may not be covered by the manufactur-
er’s warranty if they result from the use
of:
1. Gasohol containing more than 10% ethanol.
2. Gasoline or gasohol containing methanol.
3. Leaded fuel or leaded gasohol. "E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15 per-
cent gasoline, and is manufactured
exclusively for use in Flexible Fuel
Vehicles. “E85” is not compatible with
your vehicle. Use of “E85” may result in
poor engine performance and damage to
your vehicle's engine and fuel system.
KIA recommends that customers do not
use fuel with an ethanol content exceed-
ing 10 percent.
FUEL REQUIREMENTS
CAUTION
Never add any fuel system cleaning
agents to the fuel tank other than what has been specified. (Consultan authorized KIA dealer fordetails.)
WARNING
• Do not "top off" after the nozzle automatically shuts off when
refueling.
Tighten the cap until it clicks one time, otherwise the Check Engine light will illuminate.
Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci-
dent.CAUTION
Never use gasohol which containsmethanol. Discontinue use of anygasohol product which impairs dri-vability.
CAUTION
Your New Vehicle Limited Warrantydoes not cover damage to the fuel system or any performance prob-lems caused by the use of “E85” fuel.

Introduction

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
quality gasolines treated with detergent
additives 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 Warrantymay not cover damage to the fuelsystem and any performance prob- lems that are caused by the use offuels containing methanol or fuelscontaining MTBE (Methyl TertiaryButyl Ether) over 15.0% vol.(Oxygen Content 2.7% weight.)
