Downloaded from www.Manualslib.com manuals search engine Here are things some owners  ask  about.  None of these indicate  a  problem 
with  your  fuel gage: 
0 At  the  gas  station,  the  gas  pump  shuts  off  before  the  gage  r\
eads  full. 
The fuel tank  will  take  either a little more  or a little  less fuel  to fill  up 
than  the  gage  shows. 
The  gage  moves  a  little  when you turn  a  corner  or  speed  up. 
The gage  doesn’t  go back  to  empty  when  you  turn  off  the  ignition. 
For  your  fuel tank  capacity,  see  the  Index  under  “Fluid  Capacities.” 
Oil Pressure Gage 
Standard Cluster Digital Cluster 
The oil  pressure  gage  shows  the  engine  oil  pressure  in  psi  (pounds  pe\
r 
square  inch)  when  the  engine  is running.  Canadian  vehicles  indicate 
pressure  in 
kPa (kilopascals).  Oil  pressure  may  vary  with  engine  speed, 
outside  temperature  and  oil viscosity,  but  readings  above  the  low  pressure 
zone  indicate  the  normal  operating  range. 
A reading  in  the  low  pressure  zone  may  be  caused  by  a  dangerous\
ly  low  oil 
level  or other  problems  causing  low  oil  pressure. 
On  the  digital  cluster,  a  box  around  the  oil  pressure  symbol  \
will  begin  to 
flash  when  the  oil pressure 
is low.

Downloaded from www.Manualslib.com manuals search engine NOTICE: 
If you  try to do your  own  service  work  without  knowing  enough 
about  it, your  vehicle  could  be  damaged. 
The  8th digit of your  Vehicle  Identification  Number (VTN) shows  the  code 
letter for  your  engine.  You will  find  the  VIN  at  the  top  left 
of your 
instrument  panel. (See  “Vehicle  Identification  Number” 
in the  Index.) 
Use  regular  unleaded  gasoline  rated  at 
87 octane or higher.  With  the 
4.3L  (Code 
W) engine, use premium  unleaded  gasoline  rated  at 9 1 octane  or 
higher  for high  power  performance,  when  towing  a trailer or with  a  high 
payload  requirement.  But  when  operating  with  a  light load as a normal 
condition,  you  may 
use middle  grade or  regular  unleaded  gasolines. 
The  gasoline 
you use  should  meet  specifications ASTM  D48 14 in the U.S. 
and  CGSB  3.5-92  in  Canada.  These fuels should  have  the  proper  additives, 
so you should  not  have to add  anything to the fuel. 
In  the  U.S.  and  Canada, it’s  easy to be  sure 
you get  the  right  kind of 
gasoline  (unleaded).  You’ll  see  “UNLEADED”  right on the pump.  And  only 
unleaded  nozzles  will  fit into  your  vehicle’s  filler  neck. 
Be  sure  the  posted  octane  is  at least 
91 for premium, 89 for  middle  grade 
and 
87 for  regular.  If the  octane  is less  than 87, you  may  get a heavy 
knocking  noise  when  you  drive. If  it’s  bad  enough,  it  can  damage your 
engine. 
If you’re  using fuel rated  at 91  octane  or higher  and you still  hear  heavy 
knocking,  your  engine needs  service.  But  don’t  worry  if 
you hear  a  little 
pinging  noise  when  you’re  accelerating  or driving  up  a  hill. That’s  normal, 
and  you  don’t  have 
to buy  a  higher octane fuel  to get rid of it. It’s the heavy, 
constant  knock  that  means 
you have  a  problem. 
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.
