FUEL RECOMMENDATIONS
Use unleaded gasoline with a pump octane rating of 90 or higher.
These engines are certified to operate on unleaded gasoline. Unleaded gasoline produces
fewer engine and spark plug deposits and extends exhaust system life.
Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid getting dirt or
water in the fuel tank.
Occasionally you may hear a light ‘‘spark knock’’ or ‘‘pinging’’ (metallic rapping noise) while
operating under heavy loads. This is no cause for concern.
If spark knock or pinging occurs at a steady engine speed, under normal load, change
brands of gasoline. If spark knock or pinging persists, see an authorized servicing dealer.
Running the engine with persistent spark knock or pinging can
cause engine damage.
Running the engine with persistent spark knock or pinging is misuse, and the
Distributor’s Limited Warranty does not cover parts damaged by misuse.
