The engine light went out when I got back to the states and ran US gas through it. I did a little reading on the internet. Canada still uses MMT during the winter which is not recomended according to the owners manual.
While in Canada I only used ESSO and Chevron. Of course nothing on their pumps stated what additives were used.
I just got the onstar email and everything is good.
Just a thought...Any comments or problems from Canadian Hummer owners?

What's interesting is it didn't show up on the diagnostic email I recieved yesterday.

is the cylinder head issue fixed in the '07 h3s?
What good is a Hummer if you don't use it.
ah, it wasnt clear in the messages i was reading that they actually changed thr head design in the late '06's, because some of the messages were very current and those people were having head problems. it wasnt stated whether their vehicles were 06's or '07's. whew. thanks!
