BJ3 i watched your videos and there is one that shows a 4cyl diesel in an astro van, what motor was used in that one? 4bt? the 4bt is not a cheap motor however finding a old Merc motor is not so tough even in you have to part out the donor car....

That's got a 1980 240D 616 in it, turbocharged just like bio240D's car. Though I have not modified the IP yet, so its not putting out the power it should.

I get around 28 Mpg in my 240D with the autotragic. I think the best was 31 the the worst was 22 back when I first got the car with a lot of deferred maintenance needed.

I'm jealous of BIO240D
I know he says that is dead simple, but I would F that up in heartbeat.
I keep my hands out of stuff like that.
Bolt on parts are as far as I go.
Although I wouldn't have a problem getting a part fabricated as I know some machinist who spend all day doing boring stuff and would enjoy making something interesting for a change.

Bio240D,
I also have a buddy who is a diesel mechanic who claims you can add a little pigtail to the turbo which will gain you 3 pounds of boost. Would you need to adjust the IP for that little increase or would it compensate.

Yeah, that's undefined! So Stretch's mileage is "undefined"! That's almost as cool as "unauthorized".

Please note I didn't quite say that - I got my less than one figure by starting out with one of the zeros and thinking => "well that's a suitable engineering approximation'!

That sounds terrible - like it'll never get better

82 300D, auto. Usually got around 22mpg, saw 28mpg once but that was a rarety going 50-55 the whole way

chasinthesun 01-07-2014 11:40 AM

Im glad to say I get around 20 mpg ,I do alot of stop and go ,I would imagine 25mpg would be doable if I stayed in the slow lane but thats not practical,down here every lane seems to be the fastlane.

boneheaddoctor 01-07-2014 12:47 PM

83 300d Turbo....automatic..I average 26-27 on a local 50/50 city highway circuit between home and office....on 100% highway (say on a trip from Washington, DC to North Dakota averaging between 70 and 80 mph) I averaged 31 mpg once I got past the Allegany mountains. (mountains do a job on mpg)

ROFL
 
At the moment MPG is horrible.
Weather and road conditions are forcing most driving in second with rare moments in third gear.
Eighteen miles in second gear really sucks LEMONS.
The sub-zero (-16) temperature is below road salt effective temperature range = ice covered roads..

High (crazy) expressway speed has been 45 MPH for several days, 20 - 30 MPH is average.

Haha.

I can beat that. My 83 300TD gets less than 0 as well, except it has been running several times, but hasn't moved under it's own power. I've moved it about 4 feet forward. So that's...

4 ft = .00076 miles. And since I was pushing it backward... that's -.00076 miles :D

Probably has gone through a little over a gallon in fuel.

So -.00076/1 = -.00076 mpg!:cool:

Where's the like button - oh yeah that's the new thing on BW...

My 1982 240D stock avg 22-23 driving city and some 65 mph highway on good diesel. The 240D speedometer is about 10% off high on these vehicles so reality may be lower 20's.

Any idea how many rpms at 60 with stock rear end? By noise it sounds like +4000 rpm.
