My '01's manual says it can handle E10.
IIRC, they don't call it E10, but say up to 10% ethanol belend is OK.
Still, I won't use it in anything I own unless I have no choice. I used to run it in my cars until I got a warning from a friend who is a long-time mechanic at a GM dealership and he told me of how many cars they get in with carb & FI problems from running it, so I switched. I noticed an immediate improvement in performance and economy when I went back to straight gasoline.
