Well, I just paid over $42 for 11 gallons x $3.83 to fill up 'Miss Diesel', my automatic '82 240D. Good thing I usually only fill it once a month.
According to the odometer, I got about 20 mpg on the previous tankfull. That's with nearly exclusively short-trip, stop & go local driving, and before I changed the thermostat and injector hoses. So I'm still hoping for a noticeable MPG improvement with this tankfull.
Or else 'Miss Diesel' may wind up with parked more often.
(And I may have to get my moped out of mothballs!)

Happy Motoring, Mark

Finally found some measured miles and the Odo was off about 2 tenths every 10 miles... It is possible that the snow tires are the reason... Has anyone done research or posted mileage results for over-sized tires??

When I was measuring in the summer, I was getting between 25-28 depending on the amount of Bio I was mixing in.

I haven't done a precise calculation, but I think I have been getting 23-25 in the winter, though I noticed on my way to work that I hit the 200 mile mark on my trip odo and the guage was still slightly above 1/2, so I might be getting higher than I thought (but it is also getting warmer and less stop and go due to better road conditions).
