Just finished my first full tank of diesel in my new (to me, obviously!) '87 250D. I chucked in half a gallon of ATF (autobox fluid - very detergent to clean the fuel system!) along with the tankful of diesel. What a result! It idles better, runs more smoothly and quietly, and even pulls harder! (Well, as hard as 94bhp can pull in a ten-ton tank!). Excellent stuff, thoroughly reccomended to you older diesel owners (coming up on the quarter million mark here).
I think I'll throw in the other half gallon with the next fill, just for good measure.......
