I started with 30 mL (1 oz) of 87 Shell gasoline doped with various additives, except for the control jar with no
additives. The gasoline was confirmed to contain approximately 6% ethanol (Shell pump was labeled “up to
10%”). All jars had 0.3 mL water added that mixed well with the E10 gasoline. Jars were covered by lids, but
vented several times a week to provide fresh air (oxygen). After 3 months exposure to sun and air outdoors
(September-December 2012) very thick orange semi-solid deposit was found in all jars, see below. It was hard
to see differences, except some appeared more solid and some were semi-liquid.
