The MG engines will run fine with the ethanol. It has high anti-knock
qualities, though there is less energy in a pound of the stuff than there
is in real gasoline. So you trade off cooler-burning and improved
exhaust valve life for greater fuel consumption. It's OK overall.
I've read in a number of places that the alcohol that's such a good
solvent for inks and other things is also a solvent for some of the
gaskets and hoses we have in the old cars. I know it does a good job of
hardening & cracking the diaphrams that Tecumseh used on its lawn
equipment motors, having replaced three of them in the past six months.
Alcohol has been in USA fuel for a decade but I believe the % in the
mix has been increased recently as it is used to replace or supplement
the MBTE (MTBE?) that has been withdrawn. About all one can do is to
keep a watch on the fuel lines, carb and fuel pump. If the rubber is
old, it's a good time to fit new hoses before prime driving season
anyway. While it may be a problem, it's not a bad one, nor
insurmountable, so don't worry much about it.
