What gasoline do you use in your S550/S500?

I was wondering what do you guys use in your cars, the manual says ron 95 (min 91), but if use 98 or 99 octane fuel might I do something harm in the long run? In my past cars recommandation has been MIN 95 octane, so what I should use? I know it doens't probably matter what I use, but still wanted to ask I have once tried 98 but didnt really notice the difference, some people say they can feel the difference in acceleration between 95 and 98 Here in Finland fuel is high quality stuff if that makes any difference.

You will not harm the car by using higher octane, and you will probably only notice a difference when you are driving at very high speed / load, where the extra knock protection will matter. 95 is the minimum, which means it is okay, and of course, so is higher.

rajwanys550,

if you dont mind me being nosey, where do you own your property/properties?

I too am in the gas business. As you may know, its an inconsistent business as far as profits go. I can talk all day about our business and how us(dealers) ruin the market for ourselves.

Thanks! Take care
