city mpg e300 low or not?
My GFs 98 e300 is running low mpg city. About 21mpg city and she drives very, very conservative. The car doesn't shift over 2500rpm when she drives. The car is supposed to do at least 25 city I thought. it has 260k, no fuel leaks good filters. I maintain the car well. My 99 does 24-25 city..
any ideas?

Tires? Alignment? Brakes dragging? 4mpg difference is a small enough gap that it could simply be down to driving habits. Constant throttle vs a hunting throttle can net you 3-4mpg right there. So even though she's driving slow, if she's feathering the throttle, out goes your mpg right there. Torque converter locking up properly? FWIW, I average 23-24mpg in my SDL, I'd expect the W210 to do better.

23 isn't too bad depends on your throttle.. I remember hearing your car run, it had that little clack to it for a few seconds on startup.. usually when the injectors start leaking and the nozzles are old, they get more clack. might be why you're running little bit lower than my car. my car has had 3 sets of injectors .. how's that gold e320 running?

worn out injectors? conventional wisdom says they're due for a rebuild every 100k miles or so.
clogged intake manifold? 260k miles of ccv and egr can make for a constricted sludged up intake. dry wheel bearings? the front bearings in particular seem to need replacing on these cars about every 150k miles. brand new w210 front bearings/hubs come with a tiny blob of grease in them, i always repack them before installing, using only the neon snot colored genuine mb bearing grease, it's excellent.

Use Kreen 500 miles before your next oil change, I did that both in my tank and engine on my OM606. I just can't brag enough about Kreen, the injector knock were gone and the oil (drained) came out like gooey tar.

that's awful. What did you spend like multiple hours idling in traffic?

keen? that stuff worries me putting in your oil. I'd be afraid it washes stuff away it isn't supposed to. if your car came out gooey and tarry that tells me your car has missed a lot of oil changes

Nope all oil change done around 7.5k usually Rotella Synthetic but the car had almost 300k miles. Your gas mileage would increase too.

hmmm interesting. I'll have to give it a shot but it scares me. if it's such a strong detergent, Id worry it would wash away bearing surfaces etc. Mobil 1 synthetic cured my noisy lifters on my daily driver.. I had a nice tick when I got the car and 0w40 fixed it after 4k

OP mileages sounds about right for a diesel. Very high if your car is a gasser.

FWIW our average mpg on the 98 E300 is 26.5. Best tankful I every got (all highway) was 30.6. And everything is in perfect working order. So there's nothing unusual about low 20's for all city driving.
Not sure where you got the impression of at least 25 city. There some people who boast of 35-38 highway on these cars...I just don't believe it.
