New personal record, 847 miles on this tank of fuel!

Superceded my previous records of 775 and 801 miles per tank.

When I filled up I put in 22.319 gallons, so I had at least 30-40 more miles in there. I didn't baby the go-pedal until the reserve light came on for the last 30 miles or so to reach my normal fill-up station. Driving is about 80% highway, 20% in town.

I'd bet that I could easily make 900 miles if I really babied it and cruised at 55 instead of the normal 65-70.

I assume you're talking about your 95 E300D.

Is that a comfortable highway car?
I'm looking out for the big sedan, something like the 86 or 87 300SDL but if you're getting that kind of millage, I might just consider the E300.

What kind of repairs have been done to the car that might effect performance?

The secret is the big fuel tank. What is it, Chris, about 22 gallons? Mercedes advertised this car as having a 750 mile range. Even so, that's 38 mpg, Chris, are you sure?

It must have the 90L tank (23.75 gal); the Russian EPC shows a 70 & 90L tank used in the W124 with the 606.910.

Pretty phenomenal mileage. Stock rims and rubber? Have you checked the odometer with a GPS unit for accuracy?

I don't belive you!

If that's the case, I'm going out and finding an e300D. My 85 300D is a guzzler at 26-27 mpg on nearly all highay driving!

I believe him, W123 Diesels are not all that fuel efficient by modern standards. My 91 300D 2.5 turbo routinely delivers 35-36 MPG on the highway and I believe the 95 E300 would do about the same.

You are doing well.

My 93 300D averages 34 mpg. I have the 18.5 USG tank in mine. Taking it down to .5 gallons left would give me 612 miles per tank. I usually chicken out though and fill up around 500-550 miles.

I haven't taken it on a trip yet, maybe my MPG would be better.

Do you use any additives? I'm using 12oz DK w/ Cetane booster per tank full.

If this is accurate, your doing very well. I also drive about 80/20 highway/city. Best I can get consistently is around 620 miles before I fill er up. Even long trips to Chicago and Knoxville from Northern Virginia don't get me even close to your kind of range. I've tracked mileage for every tank for the past 5 years and throw the receipts in a bag. Next week I'll make my kid set up a spreadsheet and calculate average, best, etc, and post results. Are you doing anything special? Tire pressure? Driving downhill both ways? Believe me, I'd like to know how to bump mpg by 20%. Respectfully dubious.

I also got the "over 600 miles" tankful last tank. About 617 miles I believe. Came out to 33.37mpg in about 60/40 -70/30 city to hwy driving.
Love the OM606.910!!!!!
I can't imagine over 800 miles. Holy crap.......

It is a 90 liter tank, which is, for all intents and purposes, 24 gallons. I agree that the mileage is very good. I have tracked every tank since I've had this car more than 4 years and ~150,000 miles, and this was the best. In hot weather the mileage is definitely better than in winter. I did not use A/C during this tank, not any concious choice to get better mileage, I just didn't really need it during the week. Nothing special about my route or tires (195-65-15, ~30 psi) or anything else. Have not checked odometer accuracy with a GPS but no reason to suspect it is inaccurate.

I am usually pretty anal about filling the car to the brim, the same way every time, and I fill up at a spot where my left front is slightly down hill, which is good for about a gallon more into the tank than on level ground, and I let it burp the air out several times while topping off, the point being that I am consistent so that I try to make my mileage calculations accurate. And I drive basically the same route, commuting 110 miles per day.

I do agree that ~38 mpg is extraordinary however, and seems a bit too good to be true as the normal average is about 34-35. Not sure why, but I'll report back at the next fillup and we'll average two tanks and see how it looks in case I somehow underfilled this one.

Except... I'm developing a knock in my engine which is getting worse. Sounds like the recent GM V8's with piston slap before warmup, except mine is not that! I think, unfortunately, that some of my grenaded vacuum pump shrapnel may have blocked an oil passage somewhere and I may be developing a bad rod or main bearing. Ugh. This is one of the best car's I've ever had, and it runs like a champ, I still wind it up to 5K once a week to do the Italian tuneup. That may have to stop, however... It will be a shame if I have to give up this car due to a catastrophic engine failure. So close to 300,000. I will bite the bullet and have it checked by my indy.

I wonder if synthetic oil will help. I don't know, I'm no oil expert, just a thought.

How do you guage when it is time to stop and get fuel at the end of a tank? If it was me, I would carry a supply of diesel in the trunk just in case. I was actually doing this last year when I needed to change the vent and return lines under the tank and I wanted the least amount of fuel in the tank when I got under there. I did run out of fuel a few times before I got around to changing the lines. It is not that big a deal, but can be dangerous depending on where you drive. If you run out while making a left turn in traffic, that can be big trouble and dangerous. If you are just driving on the highway or a country road with a good shoulder, not as big a deal. When I did run out and had to get out and pour some fuel in, it took a bit of cranking to get the fuel back up to the engine.

I've gotten just over 650 in mine, but the way I got that...no air (lovely during the fall but challenging during summer in ATL)...and 60mph on the freeway (which annoyed a few I'm sure), but I was in the slow lane. I drive 150 miles RT each day for work, and the vast majority, probs 99% is freeway.

800 miles...you're smokin' crack (said respectfully and desiring some to get 800 too lol) but that is fantastic mileage! Well done
