300d vs. 300sd fuel economy

I am going to be alot of road driving over the next 2 years and was wondering if their is much difference in fuel economy between the 300d and 300sd-81'-85'? I have had an sd and it averaged 27 highway

I don't think the difference would be that great. Though the highway ride of the SD would be better than the D.

I got a carefully measured 31.1 MPG in my 81 SD on a recent trip ,never drove over 60,was on two lane highways with lot of grades....

I think the 300SD is the W126 (81-85) ?

There won't be much difference in fuel consumption - but there would be in terms of comfort - if both vehicles are well looked after ...

Probably not more than 1-2mpg between the two.....At one time I owned a 85 SD but I have never owned a 123 diesel.....but the SD is more comfortable and if you get a later model you get ABS and possibly an airbag on certain cars....so just with the added safety may may the mpg difference meaningless
