| Subject: | Re: Auto fuel in the Lightning. |
This past Spring I had the students in my Chemistry Department's Instrumental Analysis
class analyze some "ethanol-free" premium auto gas to see if it really
was "ethanol-free." I only had them check the gas from one gas station so I
cannot comment on all the brands - although I understand that different brands
go through the same pipelines.
They found that there was some alcohol present. It may not have been ethanol,
but ethanol is only one member of the big alcohol family. It may have been methanol
(Indy car type fuel) or t-butyl alcohol (an octane booster), but there
was an alcohol present.
Of more concern was the presence of acetone (think fingernail polish remover).
This is a great solvent for a lot of organic compounds and plastics. I would
not want even a trace of acetone in my fuel.
The strong recommendation to use only 100 LL is well founded.
