I must've missed that part, could you point it out to me, please ?
"The
emissions of toxic carbonyls such as formaldehyde, acetaldehyde and acrolein
are increased slightly on all vehicles, ..."
"It should be noted that because oxygenates contain oxygen that can
not provide energy, they will have significantly lower energy contents."
And he carefully ducked the question of what happens when burning RFG in
cars not designed for it...

"These highly aromatic gasolines can result in
in damage to elastomers and increased levels of toxic aromatic emissions
if used without exhaust catalysts."
- Elastomers being a fancy name for carb gaskets, soft fuel lines, fuel pump
diaphragms, etc...
