[T3] Ethanol in Gas


Hello Volks,
There was an interesting article in the paper today about the alternative
fuel e85 - a blend of 85% ethanol and 15% gasoline. Wanted to hear some
input on how ethanol affects/does not affect our older VW engines.  There
was also a  web site link for more info www.e85fuel.com.  With the past
discussions on higher CO2 emissions from our cars, I was curious if this was
an option?  The website states that there is only one major additional part
that is included on an Flexible Fuel Vehicle (FFV) - the fuel sensor that
detects the ethanol/gasoline ratio. A number of other parts on the FFV's
fuel delivery system are modified so that they are ethanol compatible. The
fuel tank, fuel lines, fuel injectors, anti-siphon device and dashboard
gauges have been modified slightly. Alcohols are corrosive. Therefore, any
part that comes in contact with the fuel has been upgraded to be tolerant to
alcohol. Normally, these parts include a stainless steel fuel tank and
Teflon-lined fuel hoses. Also stated was that the e85 provides a higher
octane rating than regular unleaded and that the gasoline is added to
provide good cold start and warm up performance due to ethanol's low
volatility, which results in more difficulty vaporizing at cold starts.
What do y'all think :)
