Only concern I can imagine is that the correct air:fuel ratio for ethanol is 
about 6:1 rather than 14.7:1 as with petrol. Fuel metering would have to be 
completely remapped. Modern fuel hoses should be fine.

    Anyone aware of any studies looking into any problems that may be caused by 
using Ethanol in EFI equipped engines?

    Not govt. propaganda - real world info,
 
    Have been reading some forums - small engines mostly - like outboards and 
lawn mowers who are having problems directly related to higher Ethanol content.

    They say part of it is due to the way small engines are used Vs larger car 
engines.  Since small engine sit for longer before burning their fuel. The 
ethanol is said to break down, lose octane numbers and begine to absorb 
moisture more quickly.  Evidently there is a lawsuit of various Outboard Engine 
Manufacturers Vs the Govt who mandated the use of Ethanol.  Seems they claim a 
high amount of repairs being  caused by Ethanol - especially warranty work 
which is borne by the manufacturers.  No one is looking out for the little guy 
constantly having his OB or mower repaired at hios own cost.

    Actually, my Toro had a problem with the needle valve seat which failed to 
seal -  the shop that sold me the parts blamed ethanol saying they were seeing 
dozens of them a month lately.   Were so backed up they could get to me for 2 
weeks.  Fixed it myself - 

I'm still searching the net for info but would be interested in any info. you 
are aware of -- 

Thx -

Take Care,
Larry T
