Downloaded from www.Manualslib.com manuals search engine What about gasoline  with blending materials that 
contain oxygen (oxygenates), such  as 
MTBE or alcohol? 
MTBE is “methyl tertiary-butyl ether.”  Fuel  that  is no 
more  than 
15% MTBE is fine  for  your vehicle. 
Ethanol is ethyl or grain alcohol. Properly-blended  fuel 
that  is no more than 
10% ethanol is  fine  for  your 
vehicle. 
Methanol is methyl or wood alcohol. 
NOTICE: 
Fuel  that  is  more  than 5% methanol is bad  for 
your  vehicle.  Don’t  use  it. It can  corrode  metal 
parts 
in your  fuel  system  and  also  damage  plastic 
and  rubber  parts.  That  damage  wouldn’t  be 
covered  under  your  warranty.  And  even  at 
5% or 
less,  there  must  be  “cosolvents”  and  corrosion 
preventers  in  this  fuel  to  help  avoid  these 
problems. 
Fuels in  Foreign Countries 
If  you  plan on  driving  in another country  outside  the 
U.S. or Canada, unleaded  fuel may  be hard to  find. Do 
not use  leaded  gasoline.  If  you use even  one  tankful, 
your  emission  controls  won’t work well or  at  all. With 
continuous  use, spark plugs can get  fouled, the exhaust 
system can  corrode, and your  engine  oil  can deteriorate 
quickly.  Your vehicle’s oxygen sensor  will  be damaged. 
All  of that means costly repairs that wouldn’t  be covered 
by  your warranty. 
To check  on  fuel  availability,  ask  an auto  club,  or 
contact  a major  oil company that  does  business  in  the 
country where you’ll  be driving. 
You  can also  write  us at the following  address  for 
advice.  Just tell 
us where you’re going and  give  your 
Vehicle  Identification Number  (VIN).
