A CAUTION:
You can be injured if you try to do service work on a vehicle
without knowing enough about it.
Be sure you have sufficient knowledge, experience, and the
proper replacement parts and tools before you attempt any
vehicle maintenance task.
Be sure to use the proper nuts, bolts and other fasteners.
“English” and “metric” fasteners can be easily confused.
If
you use the wrong fasteners, parts can later break or fall off.
You could be hurt.
FUEL
Use premium unleaded gasoline rated at 91 octane or higher. It should
meet specifications ASTM
D4814 in the US. 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.
If the octane is less than 91, you
may get a heavy knocking noise when you drive.
(In an emergency, you
may be able
to use lower octane -- as low as 87 -- if heavy knocking does
not occur.)
If you’re using 91 or higher octane unleaded gas and you still
get heavy knocking, your engine needs service.
