Re: IS IT POSSIBLE TO PUT E-85 FLEX-FUEL

Possible, yes. Advisable, no.

In the stock xj it can eat away a lot
of the plastic and rubber fuel system.
Plus the engine is not set up for the
correct timing and compression required
to efficiently use ethanol fuel.

To do this your looking at changing out
the fuel system, different injectors,
highly advanced timing and even increasing
compression (stroking) the engine.

Keep in mind that E85 is no good at all
in cold weather. You will need gasoline
to start and warm the engine up. That's why
some E85 vehicles have a small 1/2 gal gas
tank.

Now, think about the prior paragraph. Increased
timing and compression plus gasoline = *paff*
so the computer has to be able to detect what
the engine is running to keep from grenadeine.

There is a discussion here.

The key item is E-85 reduces your economy by about 25%
i.e. rather than getting 20mpg you will get 15mpg. So
any cost savings in $/gal are wiped out.

Long story short.
Ethanol belongs in the pub, not the pump. :)

Re: Related Question, but different
 

If it is not permissible to use E85 fuels, what is going to happen to all of
the legacy engines on the road today if E85 becomes mandated?

I remember gas stations having to stock leaded and unleaded gasoline to meet
the demand of the legacy that was already on the road, but eventually there
was a clean switch to all unleaded fuels, and the legacy engines had to have
stuff changed, or I suppose those drivers have to buy leaded additives to
use in their cars -- but this would defeat the rules that caused the
changes in the first place.

So, what is going to happen to all of the millions upon millions of vehicles
with engines that do not tolerate E85, and E85 becomes the only fuel
available?

Pretty much what happens soon when our loyal gov't servants have decreed
a cutover to high def TV coming soon to every TV set near you. In
technical terms, you are screwed, and worse you voted for them to do it.
OK, for TV there is expected to be some modest market in conversion boxes.

For autos, the makers are somewhat in conflict. They would be expected
to bear the brunt of much automobilic wrath as folks realize what their
gov't has done to them, but on the other hand, the bump in sales as
folks end up having to buy all new power plants, conversions, vehicles,
would be difficult for a capitalist to ignore.
