Just so I understand correctly, are you using 89 on your 300 E when the manual/fuel guage states "Premium Gas Only"? or does your manual allow for 89.

ANother interesting thing is that when MB says premium, what does that really mean? In some countries 89 might be premium, I don't know.

The important question is what is the octance acceptability range for my 300 and 420???
