Purchased my 97 E300D on 11/20/07 with 162k on the odometer. Rolled 171k two days ago. This makes 9000 miles on a 90%WVO/10%RUG blend. I filter the WVO to 5 micron.

I have been changing the spin-on fuel filter about every 800-1500 miles when I witness a little stumble at highway speeds. I figured I'd be through the filter-changing phase by now. I'll chock that up to possibly not-fully-dewatered WVO, but I'm not sure.

Love the car. The 83 sits in the garage ready to go, but the 97 is so much more comfortable and nicer to drive that I seldom choose the 83.

No operational issues except for one bad glowplug (I got lucky it was #4, which is changeable without removing the manifold), and a burned out license plate bulb.

I get 26mpg consistently, which is a drop from the 29 or so on the first tank of diesel when I first bought it (but I did put slightly larger tires on it soon after I bought it).

Combining the cost of vehicle filters, WVO-filtering filters, and the RUG, it costs me about $.02 per mile to operate.

As another poster put it..."all hail the mighty 606!"
