loing Your Own Service Work
F YOU want to do some of your own
ervice work, you’ll want to get the
lroper Geo Service Manual.
It tells you
mch more about how to service your
;eo than this manual can. To order the
. . .I56
xoper service manual, see “Service
Publications” in the Index.
You should keep a record with all parts
receipts and list the mileage and the date
Df any service work you perform. See
“Maintenance Record” in the Index.
NOTICE:
If you try to do your own service
work without knowing enough about
it, your vehicle could be damaged.
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.
But don’t
