This is what my family does:
Dad
S Class 5.0 Litre V8 Premium
Mom
ML Class 3.7 Litre V6 Regular
Me
SL Class 6.0 Litre V12 Premium
In the ML, regular works fine. I would have no problem advising you to use regular except after reading an earlier post about the car's computer and its inablility to adapt to a different grade of fuel. My advice would be to check with a private MB Specialist (not the dealer). My best guess would be that the 300 would work fine with regular based on my experience with the 3.7 Litre ML. But double check before you switch.
