When I had my 90 300D 2.5, I did that and then followed this procedure (i.e. the Italian tune-up) and it would always clean a lot of crud out and run better. I think it improved the mileage.

[MBZ] Troubleshooting cr*ppy fuel economy in a W123 turbodiesel wagon
I hate it when people complain that their 300D fuel economy is only in the mid 20s mpg. My daily driver 1983 300TD with a 1985 transmission gets exactly 20 mpg for mixed, mostly in-town driving. This dips to under 19 mpg in the winter. :(( There are no fuel leaks whatsoever. The car starts and runs with great power. Tires are 205 X 70 X 14s, average tread and inflation pressure. I might even consider loaning out the car to someone with the ability to diagnose the problem and do whatever it takes to improve fuel economy by at least 20 percent.

Re: [MBZ] Troubleshooting cr*ppy fuel economy in a W123 turbodiesel wagon
I have often thought that these claims are inflated, as I have owned both normally aspirated and turbocharged 123 chassis cars, and never seen the mid 20s during normal driving. During highway miles, certainly, but around town I rarely got better than the high teens or low 20s. I also kept (keep) meticulous records on my cars, so I feel pretty confident about my findings.

Re: [MBZ] Troubleshooting cr*ppy fuel economy in a W123 turbodieselwagon
hi Andrew! our '85 (Calif) 300D is routinely driven in a manner we'll call 'briskly', and averages just about or barely above 20 MPG on (almost exclusively) B99.9 in mostly Kombat Kommute traffic (which means either crawling or flying). we don't use it much for around-town. on open highway trips it's not much different, but that's not surprising since again, that's typically 80+ MPH. WRT the CD, not only are they slightly shorter presenting a smaller frontal surface area in a critical area, but didn't they also have a different rear axle ratio? cheers! e On 06/Dec/12 10:26, Andrew Strasfogel wrote: Great feedback.

Re: [MBZ] Troubleshooting cr*ppy fuel economy in a W123 turbodieselwagon
With the gearing in the 85 models they don't start getting superior mileage until you cruise at 85mph plus for a tank of fuel. We have run my friend Jon's 85 td from upstate NY to the Outer Banks of NC twice this summer. The car always gets better mpg at higher highway speed. Figured 35 on one tank that had a lot of steady, nighttime 100mph plus driving. On the first trip back Jon drafted right on the bumper of the Deuce all the way back home from NC. We averaged 40mph and he got over 40mpg for every fillup. He was following close enough to BE my tail lights as I had none until we got to Harrisburg, PA.

With the idi Ford 7.3 in my F350 putting taller tires on it and getting the rpm's under 2000@60mph gained me 3mpg on the highway.

Re: [MBZ] Troubleshooting cr*ppy fuel economy in a W123 turbodieselwagon
The reason that higher speed reduced diesel fuel economy is that higher horsepower is needed, and diesels are very output sensitive in terms of fuel consumption. They do not suffer from the charge density problems of gasoline engines (at idle, the pressure in the combustion chamber is barely above atmospheric due to the throttle closing off the air flow and producing a vacuum in the intake). Valve adjustment, timing chain check, injection timing check (if the chain is worn, replace that before checking injection timing as a worn chain produces late injection timing and a new one should restore it to where it was). Leaking valves, late timing, and late valve timing eat fuel. So does alignment or wheel bearing problems.
