Fuel Recommendations - Honda GX270 Owner's Manual

FUEL RECOMMENDATIONS

Use LPG with a propane content of 95% or higher.
This engine is certified to operate on LPG only.
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 LPG. If spark knock or pinging persists,
see an authorized Honda 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.
