This is really one question related to us living in Canada. I am curious about those who are taking their gaz at Petro-Canada. I have few questions:
1-I heard that its not good for Mercedes-Benz cars because of the fuel additives they include in it. Yes or no long term usage can bring issues.
2-I saw that they have a premium of 94 octane (other's premium is 91 octane). This is the highest I saw on the market. Is it better for our Mercedes (BTW, mine is a 1997 E320)?
3-Any other gaz station than Petro-Canada that offer higher than 91 octane?

I've never heard that Petro Canada gas is bad for MB based on the additive package. As far as high octane is concerned, you can get 93 octane from Sunoco stations. However, as your car is designed to run on 91 octane fuel you wont achieve any benefit unless you are able to advance the spark timing to take advantage of the higher resistance to detonation that a higher octane fuel has. As your computer controls the spark timing there is no way to do this (on old carbureted cars you could do this easily).

Save your money and stick with the 91 octane.
Hi Jlomon,
FYI we don't have Sunoco's here in Quebec Province. Are you using Petro-Canada and also in the winter? I also heard that they change their mixture for winter time. May be this is at that period of the year that it isn't good for M-Bs.
First, identify the source of the information that advised Petrocan gas is somehow 'bad' for MBs, then we can determine their credibility.
Second, it is my understanding that ALL gasoline companies in Canada alter the forumulations of their fuels depending upon the season. 'Winter' gas has a different forumulation to help cars start more easily when it's -35 C. At least that's my understanding, and it seems logical to me.

Hello T-88,
Thanks for your comments. I heard/or read Petro-Canada's story a while ago (around 3 years ago).
I don't remember exactly when and where I heard/read it but it brought my attention and since, I have this in my mind. But is it a true or false assumption?
This is why I post this thread to have the exact information about yes or not long term usage of Petro-Canada fuel may cause issues for M-B?
