Fuel Gage
Your fuel gage shows about how much
fuel is in your tank. When the gage first
indicates “E,” you still have a little fuel
left (about one or two gallons), but you
need to get more right away.
Here are four concerns some owners have
had about the fuel gage. All these
situations are normal and do not indicate
that anything is wrong with the
fuel gage,
At the gas station, the fuel pump shuts
off before the gage reads
“F.”
It takes more (or less) fuel to fill up
than
the gage reads. For example, the
gage reads half full, but it took more
(or less) than half
of the tank’s
capacity to fill it.

The gage moves a little when you
turn, stop
or speed up.
When you turn the engine
off, the
gage doesn’t go back to “E.”

Fuel
Use regular unleaded gasoline rated at 87
octane or higher. It should meet
specifications ASTM D4814
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 87. 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 87 octane or
higher and you still hear heavy knocking, your engine needs service.
