Newbie here not very "post" experienced and I suck at typing, having that out the way, drive a 98 Saturn SOHC/5 speed, box stock best 39mpg@65-70 and I just picked up a 96 300E diesel, trip from Lubbock to Pittsburgh got 41.3@75-80,32.2@80, and 33.5@70-75. Am an A/P mechanic, former Ford driveability tech/ASE Tech. Anyone out there done a WVO mod on one of these Benz? I'm gonna begin my research on the injection system on the car whilst looking for a good set of factory manuals or alternatives..........any suggestions to prevent "re-inventing the wheel would be appreciated.
