So in my 82 300D im only getting 20mpg, at most. I adjusted the valves, but have not got around to IP Timing. Not sure what gears i have, but i run around 3000 rpm at 70mph.
Any help is much appreciated,
Eric

No I wouldn't expect them to once its in the tank, just getting caught filling. Unless you work construction or something and get it that way, the place by us where we get it has a big UNLAWFUL blah blah blah sign on the pump.
I don't know of anyone truthfully getting that kind of mpg unless its pure highway. I have to see what kind of gains I'm getting from the vnt, the tank does seem to be lasting longer though. Before the turbo swap I was getting 24 with mixed driving on summer diesel.

It's working out great so far, really pulls hard off the line now. I plan on creating a "how to" thread soon instead of just adding to my car profile. I'm still not completely done with the oil drain and a couple other things, I want it to be definitely a check in the win column before I go showing off

Does your pump have enough fuel to support it throughout the rpms?
