RE: W114 and a 250D engine??

If I remember correctly, my W114 twin Zenith 2.8L M130-powered 250 always got around 18 MPG on the road (It's not ON the road that much anymore). Even before a rebuild at 150K miles...

At 6.6MPG, you have a serious problem that needs to be fixed. Slipping transmisson, maybe ?? I can't imagine any fuel-mileage related problem (except the transmisison) that would cost near as much as a complete diesel swap !

edit..

Oh, you said replacement clutch - so you have a gearbox...
