Well you could have had
30% reduction in mpg with ethanol, but I'm glad you did not.
When MPG drop is higher than average/expected it is almost always due to improper blending of ethanol resulting in excess amounts (very high %)...
This also can also happen when E10 gas phase separates (P/S)=
When water saturation limit reached, most of ethanol drops to bottom of tank with water - Resulting in a very high concentration (60-95% ethanol) at bottom of tank- Running this would drop MPG greatly and likely damage your engine too -
P/S (water-contamination=W/C) is unusual with an auto, unless gas already W/C at time of purchase (more common than it should be) -
-This phenomenon (P/S W/C of E10 gas type) occurs most often in boats, lawn equipment, and other engine types that have a vented fuel system and/or store E10 gas for prolonged periods of time.
In response to some of the other comments here:
E10 is very controversial for so many reasons - Very limited benefits, often sold contaminated, has dramatically increased (unnecessary) gas-caused engine damage/problems over past 5-7 years, and many other negatives... Especially due to it being an unstable fuel type (short shelf life), ability to attract and absorb water rapidly (hygroscopic), and probably worst but not least, all the political controversy (scams).
It's well known that corn and grains could never be the sole source for ethanol
(especially if we used ethanol as E85 in all vehicles, which has the benefit of replacing petroleum) - We don't have enough open farm land to accomplish this.
Add to this, the pollution created by ethanol manufacturing plants and transporting ethanol, fertilizers, etc. and the negatives of ethanol as a fuel far outweigh any benefits.
For over a decade we've been promised cellulosic and other "non-farm sources"
of ethanol (highly subsidized, but still not available
in any markets) -
Conclusion= Ethanol needs to go away.
Than maybe the U.S. will refocus and finally develop a domestically produced, alternative energy source/type that is beneficial, so that we can become energy independent, while also protecting our environment (and pocketbooks/engines).
- -A huge task, but very possible...Which needs to start with getting the ethanol lobbyists out of Washington
and away from the politicians, local, state and federal.
- Only the public (voters) will be able to accomplish this.
Get involved, sign petitions (such as ours) which protect consumers/engine owners/environment etc. and especially ASAP contact your local leaders to reclaim availability of E0 fuel, for those who need, require or prefer this conventional fuel type.
