Repairman and small-business owner Rich Herder doesn't mince words about
the damage ethanol in gasoline is doing to the small engines in outdoor
power equipment. "It's the biggest disaster to hit gasoline in my
lifetime," Herder says. He owns McIntyre's Locksmith & Lawnmower, a
service business in Westfield, N.J. Founded in 1898 to refurbish
saddles, the business today repairs more than 5000 machines a
year—mostly pieces of outdoor power equipment, and many of them,
according to Herder, damaged by the alcohol in today's gasoline, known
as E10 for the 10 percent of alcohol it contains.


It did in my snow thrower a few years ago. Older equipment has seals
that are attacked by the higher solvent power of E10.

I remember when it was mandated in all gas stations around here and they
had to close to clean out their tanks to put in E10. Similarly they
cannot pipeline it because any deposits in tanks or pipes will have any
insoluble crud contaminate the E10.
