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
only unleaded nozzles will fit into your vehicle’s filler neck.
T- gasoline (unleaded). You’ll see “UNLEADED” right on the pump. And
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.
