RE: The Official Fuel Economy report thread
Been driving 2 weeks now..averaging 22-26 mpg depending on my driving style...using Diesel Kleen/Acetone. She runs like hell. Will post more lengthy/detailed account in future.

RE: The Official Fuel Economy report thread
Filled her up again for a run back and forth across Alligator Alley with city driving throughout the weekend. Full tank plus acetone and Diesel Kleen made 23 mpg average...and that's w/ 75-80 mph on the highway w/ some bursts of 90. LOL. She's running hard and purrs at idle as usual.
AVG MPG for 10/25/05-12/16/05 which included half a dozen fillups w/o additives: 22.6 MPG
AVG MPG for 9/2/05-12/16/05 which included 12 fillups w/o additives: 21.7 MPG
During the next 12 tankfuls, I will add 4 oz. of PowerService DieselKleen to the tank. I will calculate the average MPGs with the additives, then for the 12 tankfuls after that, I'll calculate the average MPGs without fuel additives to see if there really is any benefit mileage per gallon wise to using additives. Keep your eyes peeled.

I now consistently get 24-26MPG (sorry no mile #'s) because:
1. At night I don't want to floor it as much unless somebody is tailgating me (smoke) so I gently tap the pedal.
2. Pouring in bottles of veggie oil (unused) does make the engine run quieter and produces less smoke. No noticeable drop in power, however (it's only a bottle of veggie oil).
After the valve adjustment I hope to get high 20's. Am I expecting too much? By the way, the above figures (24-26MPG) are mixed city/highway. The throttle linkage adjustment saved me 2MPG! Calculating cost per mile came down to $0.10/mi with $2.53/gal with 25MPG as an example.
Here's some recent "Christmas trip" fuel economy numbers on our 1979 240D M/T with 319600 odometer miles:
Fresh fuel fliters and anti-freeze.
Recent oil change and valve adjustment.
K&N air filter and studded tires (195/75 R14) at correct pressure (35psi.)
800lbs of passengers and gear in the car pulling a 800lb trailer;
75% over the highway with 2 snowy mountain passes at 60mph (4th gear),
25% stop & go, town and under 40mph hilly (3rd or lower.)
We used the 'top off tank' method with 333 miles on the trip meter, 11.846 gallons of fuel for 28.11mpg.
Normally when using biodiesel, the car runs quieter and has a touch more pep but the economy is the same; our biodiesel station doesn't have 'precision' pump numbers and at 70 cents a gallon, we don't really care.
