190e 2.6 gas grade/oil changes
Just bought a 91 with 80K. 1st MB for me.
Owners manual calls for premium gas and
7500/1year oil changes. Does the car need
premium? 7500mi/1yr is longer than the 3000 miles
I am used to. When should I change the oil?
Is the oil/filter a easy DIY job? Should a MB
filter be used or after market?
