The article really doesn't explain the why of the first two points.
As to the third, I have a co-worker who, with hundreds of others, had expensive fuel system repairs because the refinery shipped gas with too much sulfur. The oil company covered the repairs, and they should be the ones responsible in cases where ethanol content exceeds 10%. The ethanol mandate has been in place in some states for years now, and it wasn't surprise that it was expanding. Car manufacturers are responsible for new cars not handling 10%.
I know I don't, and many others probably do the same, but you should be draining small engines of fuel at the end of the season even without the presence of ethanol. I remember lawnmowers being hard to start in the spring long before ethanol, and stale fuel was the likely culprit. With ethanol, I regularly add IPA to keep phase seperation in check.
I'm against ethanol as fuel. I can live with it as a MTBE replacement, but don't want anymore added into the supply when there are better options, like butanol and thermopolymerized biocrude.
IDC what anybody says, ethanol needs to be kicked to the curb, except for e85. E85 is good in my opinion for the newer cars, but I don't like somebody putting something into the fuel that my car originally wasn't tuned to run on. I noticed a bit of difference in mileage between e10 and regular unleaded gas. On my trip to FL, I got 28mpg on my way on the first tank, and then so happened I stumble across a station with ethanol free gas and that tank gave me 36mpg. Same foot, same engine, same car, same I-95. Go figure.
Not to mention I work on Chinese mopeds on the side and ethanol tears carbs up BAD. Corrosion gets inside the needle and pilot jets. You can run the stuff if you are an avid rider, but if your liquorcycle once a week, you are eventually going to be screwed. You have to use expensive ethanol enzyme that probably doesn't work.
i must have some inbreed crazy gas here cuz weve been using ethonal E10 in the pumps here since early 80's...
motors we've run and some still run with it:
1929 model A engine (carbed)
1952 evenrude outboard 2 cycle (carbed)
1960 VW ghia flat 4 cyl (it was recently rebuilt when we restored the car but still carbed and sits during the winter with last years gas - fires right up springtime)
1969 mongomery ward outboard 2 cycle (carbed)
1972-2003 lawnmowers both riding and push (all carbed)
1972 dodge ram van (full carb)
1977 chevy caprecee classic (full carb)
1980 chevette (full carb)
1982 ford escort (full carb i belive)
1986 plymoth reliant
1987 dodge aries K car
1992 GMC s15 jimmy
1995 dodge neon
1995 chevy s10 pickup
1996 saturn SC2
1996 ford aerostar
1997 ford tarus
1999 weed eater string trimmer 2 cycle
2002 chevy s10 blazer
2004 polun chainsaw 2 cycle
2007 ford fusion
(a few random snowblowers mixed in there but no clue how old they are)
whatevers left in each one stays in each one all year including the lawnmower gascan. no stabil either.
yes if all you've ran is reg gas and start putting ethonal in it will cause problems, especially the older the engine is due to varnish buildup and will eat the dried out seals.
yes you do get less mpg using E10 vs reg gas i'm not disputing that.
yea e85 is only meant for cars that's able to run it but E10 should be good for most cars id say the late 70's even (not sure when it first started appearing but my 1980 chevettes manual even says its OK to run E10) to present.
shag wagon about your trip to flordia; yea from what Ive personally noticed a 3-5mpg difference between reg and e10 in most of my vehicles but you also didnt account for traffic and wind differences and distances between the different stations. it seems the higher the MPG vehicles you see more of a drastic change between reg and e10 VS trucks with low mpg to start off and such where i see maybe a 1-2mpg difference...
the chineese mopeds carbs probably corrode up because of shotty materials because they are chineese mopeds... ive never had a B&S or techumseh or kohler or any car engine have a gas issue that wasnt caused by something else (literally dirt and grass clippings clogging stuff usually). thier all quality brass and aluminum or good cast alloy carb parts and fuel systems.
