Default Re: Getting new head

Last month I drove up to Edmonton Canada. WHile up there the check engine light came on. Onstar said it was related to changing fuel, fuel cap, ect. I don't remember the code.
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?
