CAUTION
Use of automotive gasoline containing alcohol (e.g.: methanol or

permitted.
NOTE
Petroleum suppliers provide automotive gasoline of varying volatilities, depending on the
season and climatic zone. Fuels with higher volatility (“cold weather” grade fuels) are
more susceptible to fuel vapour formation than fuels with lower volatility (“hot weather”
grade fuels), at equal temperatures. Use of fuels dispensed in winter or in colder climatic
zones, under high ambient temperature conditions, increases the risk of vapor formation
and subsequent possible engine malfunction.
