IMPORTANT
Experience indicates that alcohol blended fuels
(called gasohol or using ethanol or methanol)
can attract moisture which leads to separation
and formation of acids during storage. Acidic
gas can damage the fuel system of an engine
while in storage. To avoid engine problems,
empty the fuel system before storage for 30
days or longer . Drain the gas tank, start the en-
gineandlet itrununtilthefuellines andcarbure-
