Introduction -> Fuel requirements for Your Kia Rio 4 Door Third Generation (2017-2023)

Introduction  
FUEL REQUIREMENTS  
Your new vehicle is designed to use  
only unleaded fuel having a pump  
octane number ((R+M)/2) of 87  
(Research Octane Number 91) or  
higher. (Do not use methanol blend-  
ed fuels.)  
Pursuant to EPA regulations, ethanol  
may be used in your vehicle.  
WARNING - Refueling  
• Do not "top off" after the noz-  
zle automatically shuts off.  
Attempts to force more fuel  
into the tank can cause fuel  
overflow onto you and the  
ground, causing a risk of fire.  
Do not use gasohol containing more  
than 15% ethanol, and do not use  
gasoline or gasohol containing any  
methanol. Ethanol provides less  
energy than gasoline and it attracts  
water, and it is thus likely to reduce  
your fuel efficiency and could lower  
your MPG results.  
Your new vehicle is designed to  
obtain maximum performance with  
UNLEADED FUEL, as well as mini-  
mize exhaust emissions and spark  
plug fouling.  
• Always check that the fuel cap  
is installed securely to pre-  
vent fuel spillage, especially  
in the event of an accident.  
Methanol may cause drivability prob-  
lems and damage to the fuel system,  
engine control system and emission  
control system.  
Never add any fuel system cleaning  
agents to the fuel tank other than  
what has been specified. (Consult an  
authorized Kia dealer for details.)  
Gasoline containing alcohol and  
methanol  
Discontinue using gasohol of any  
kind if drivability problems occur.  
Gasohol, a mixture of gasoline and  
ethanol (also known as grain alco-  
hol), and gasoline or gasohol con-  
taining methanol (also known as  
wood alcohol) are being marketed  
along with or instead of leaded or  
unleaded gasoline.  
• Tighten the cap until it clicks one  
time, otherwise the Check Engine  
light will illuminate.  
Vehicle damage or drivability prob-  
lems may not be covered by the  
manufacturer’s warranty if they result  
from the use of:  
1. Gasoline or gasohol containing  
methanol.  
2. Leaded fuel or leaded gasohol.  
3. Gasohol containing more than 15  
percent ethanol

For customers who do not use TOP  
TIER Detergent Gasoline regularly,  
and have problems starting or the  
engine does not run smoothly, addi-  
tives that you can buy separately may  
be added to the gasoline.  
If TOP TIER Detergent Gasoline is not  
available, one bottle of additive should  
be added to the fuel tank at every  
7,500 miles (12,000 km) or every  
engine oil change is recommended.  
Additives are available from your  
authorized Kia dealer along with infor-  
mation on how to use them. Do not  
mix other additives.
