Against my better judgement
Agreed that these things are basically just cars but .... The manufacturer's stated fuel grade requirement is there because of the engine design. There are some Benz that are happy to drink regular fuel but yours is not one. You may, of course do as you please with your own car but I see little advantage to go through all sorts of calisthenics to avoid using premium fuel. I'm sure it is not a cost issue, you are just interested in exploring your options. I have filled a half tank of regular in my 560SL when asleep at the pump and no disaster occured but I itched until it burned down enough to refill with the proper grade.
I think, despite the dire predictions of many, few can definitely tell us the long term result of using low octane fuel. However, the proper grade of fuel will simply eliminate one point of concern in the future.
I often disagree with lkchris but as much as it pains me to agree with him, he is right on this point.
If you do as you say, please post the results so we may add to the data base.
