For those of us who try to use "no ethanol" gas for our small motor engines, we're being lied to and ripped off. At a visit to a small motor repair shop I was told that there is no such thing, it just has less than 10% ethanol. I researched and found that 5% or more is labeled "ethanol included" but less than 5% doesn't have to be noted. So at the next stop at a gas station with a "no ethanol" pump I asked if it was true. The manager showed me the invoice of his last gas delivery. It showed "4.97% alcohol" in the gas to the "no ethanol" tank. So the dealers interpretation of "no", and that alcohol & ethanol are different, is a total farce!


Not something I really keep track of, but I thought ethanol replaced
MTBE as an octane booster (because of water contamination by MTBE). (And
MTBE replaced tetraethyllead.) Wouldn't there need to be some percentage
of ethanol in gasoline unless another octane booster was used?
(Percentage would be a lot less than the ag producers want.)
Octane can be raised by the cracking and reformulaing of the feed
stock without using lead, MTBE or ethanol - it's just more expensive.
MMT is the current octane boosting additive of choice. There are also
some non-metallic orgonochemical compounds.
