Those "that did not require oil and gas mixture" to me means 4-cycle
engines. There have been 4-cycle small engines around "since
forever" so they definitely were around well before ethanol became
widespread. I was thinking specifically of the first relatively
short-lived ethanol boom during the Carter-era shortages that
affected passenger vehicles but not, to the best of my recollection,
small engines so much...

was that Ethanol,or Methanol? Methanol is really bad news.
ethanol(E10) really didn't come into use (as fuel additive) until lately.

What I was TRYING to say is that earlier in my life, all of my
mowers required the 4-cycle oil. My last few have run on regular gas
without the need for including the oil in the gas. Would THOSE (the
ones running on regular only) be more likely than the 4-cycle engines
to be more ethanol tolerant as they (seemed to me anyway) to come on
to the scene after ethanol was in wider use.


Some small 2 cycle motors use oil injection,not a gas/oil mix.
current emissions regs forced a switch to non oil-burning motors.

I don't see why ethanol is affecting small motors,unless they used really
cheap seals.AFAIK,ethanol would not affect neoprene.I couldn't find
anything on the Dupont website about it's alcohol resistance,without
registering/logging on.
