I'm currently getting low 20s for mpg. I've ordered some LM purge and I'm going to go through everything else before I swap the rear end. I've had the car about 3 weeks although this is my 4th 240 (3 115s before this). I have no service records so I have no idea of the timing chain history (200k miles on car), age of injectors, timing adjustments, etc. I do know that even when its warm outside I get alot of unburnt diesel out the tailpipe for the first minute before it warms up then no smoke in exhaust. Oil consumption is negligible. The car positively flies on the interstate from 55-75 making me think there is some room for negotiation with the rear end there.

Thanks for all of your input. I'm sure I'll find all of the information I need for making a complete assessment and all adjustments in the archives.
