Old Jetta Diesel and Water Separator
I had a 1986 Jetta Diesel (not turbo) that I finally sold in 2006 with around 300K miles. It came with a little plastic bag that you were supposed to use periodically to drain off the water. Sorry for lack of details because it was one thing I did not keep records on, but I do remember having water in that bag every time I did the exercise. I was never particular about where I bought diesel fuel. Over the life of the car I averaged 44.5 mpg.
