ethanol mix, engine life, new gas engines ?
does any one have objective information on ethanol mixes as it pertains to the honda fit gasoline motors.
I had a discustion with vendor of small outboard engins. He said the rings are made differently to accomodate the ethanol,which doesnt lubricate well. In fact he said for new fleet vehicals it shortens the life of the engine.
How does this fit in with honda motors? My first honda is still on the road past 250,000 miles. thats exceptional but what about getting to the mid 100,000 miles.
I appreciate any comments from technicians and or engineers that know about this

Honda allows up to 10 percent ethanol. Now the E15 waiver has been posted, its Ok to use in 2007 and newer cars. I prefer premium which I believe has lower ethanol or uses different oxygen barring alcohols like butanol, or eithers. If motor is maintained it should last 250000 miles or more with E10. The question is what E15 will do. Ethanol is corrosive and put out toxic Formaldehyde,Acetaldehyde while reducing Co2 a natural forming element, and Nox. http://www.iom.edu/~/media/Files/Act...ineexhaust.pdf

Depending on the PTW clearances concentrated ethanol, like E85, can contaminate the oil through blow-by and speed up wear on contact surfaces.
That is in addition to the other inherent problems caused by excess crankcase pressure, like pumping losses etc.
Basically ethanol burns cooler than a gasoline toleranced engine is set up for, and the gaps stay bigger than intended. Like .0035-.0040" PTWs vs. .0025-.0030". Some types of rubber and plastic in fuel systems can be damaged over time and eventually leak on majority ethanol blends.
Though it will keep your combustion chambers nice and clean!
Check your oil often, and smell the dipstick, if you smell E85 or the oil looks contaminated your should probably switch back to gasoline.
I like ethanol for performance forced induction applications more than economical or practical reasons.

Is your gas additive safe with E10 fuel?
Gasoline Octane and E10 Ethanol Blend Fuels
now new fuel E15 is out http://www.epa.gov/otaq/regs/fuels/additive/e15/

its my understanding that new cars are engineered to burn 10% ethonol so if you burn no ethonal gasoline does it make a difference.
Lets say a person has an new honda fit and always burns premium gasoline not containing ethonol? what would be the good choice and what would be the difference. I am courious if the days of going 200,000 miles problem free are over or has Honda engineered out of this problem?

Ethanol blends have been here in Chicago since the late 70s, They do have problems if the additive package is not right. Phase separation, rusty tanks and worn fuel pumps and carbs, injectors to list a few problems. Phase separation can be an issue especially if the car sits for long periods of time. Polyisobutene and polyisobutene derivatives for use in lubricant compositions - Patent 7071275 ,Butyl rubber - Wikipedia, the free encyclopedia This additive helps in better lubrication and use with ethanol to help resist phase separation and better oil control.
10 percent ethanol blends will produce more power than non ethanol blends. There is some sort of oxygen added to gasoline to help lower emissions. Oxygenate - Wikipedia, the free encyclopedia
Honda motors should last 200000 miles, but will require more maintenance. Short trips and lot of engine starting causes most of the wear in a motor. Knock,and over heating is the other problem. Higher octane(premium) will made your engine run more efficient and help control engine temps as long as your cooling system works fine. Lower mpg is the other problem with ethanol but not with other oxygenates because BTU's is higher than ethanol.

ethanol 10% . short thread excellent links and comments

excellent comments and links. thank you. some people I have talked to are selling gas moter equipment sooner because of ethanal. An example is my coworker sold his stihl chain saw. A boating business man told me the fuel shortens life of outbourd engines. Again thank great thread

sea faom, fuel stabilzer
Sea foam is great to fog a outboard motor after every use. It comes in a spray too. I use premium in all my small motors and even my 2 stroke snow blower with no problems even if I leave it in till next season without adding anything to it too stabilize the fuel. Right now I am waiting for E15 to start showing up so I can avoid it if I can. Outboard motors should not use ethanol fuels because of phase separation caused by temperature variations and because of operating on water. Ethanol is hygroscopic and can absorb water through the tankand lines from the air.
More good news is that stabilize is available now to help the ethonel gas mixture.

anybody got thought on the E85 gasoline, I'm thinking of purchasing the computer that will advance the timing of the fit, I'm asking around at an E85 site that converts cars so they are Flexfuel acceptable. anyone done this?
What device?
GE or GD Fit?
Timing is far from the only thing that needs t be changed. What are you looking to accomplish?
Fuel economy will nose dive on E85, so unless this is a performance oriented mod you are literally throwing money away.
