Re: [DML] What effect- Ethanol?

[<delornut@xxxxxxxxxxxx>]

One of the problems I've heard regarding gasoline today is the quality is 
not always up to par in the rush to get the product out the door. Sometimes 
there is too much sulfur in the fuel and that leaves deposits that are 
contaminating fuel level senders on many cars. We live in world that has an 
expanding population with consequently more vehicles but also with an 
expanding awarness of environmental issues. That has resulted in , among 
other things,  more need for fuel without any expansion of refinnig 
capabilities. It's going to get interesting in the coming years and there 
will be some real challenges for those of us playing with older cars.
